Plating Information

What is Plating?

Plating refers to covering a surface with a metal. 

Our technology is based on electroplating.  Electroplating is a specific plating process in which positively charged metal ions in a solution are deposited onto an electrically conductive, negatively charged surface. 

Common Materials That Can Be Plated

Copper

Copper Alloys (including brass)

Nickel

Steel (stainless steel requires special activation)

Silver

Pewter

How Does Plating Change the Properties of the Surface

Plating has been a critical element in the advancement of modern technology. Plating is used for corrosion resistance, to improve solderability of a surface, hardening, to improve wear-ability, reduce friction, to improve paint adhesion, alter conductivity, for decorative and other purposes.

  Plating-An in Depth Look

Plating usually describes a process of metal finishing   that deposits a metallic coating onto some form of substrate.  Plating is done to protect, beautify, increase corrosion or wear resistance, affect conductivity of heat or electricity and or solderability of an item.  For our purposes, plating can be generally described by two different processes, electroplating and electroless deposition.   Electroless plating involves the use of an aqueous solution containing metallic ions that is designed to deposit the metal onto a substrate through autocatalytic reduction of the metallic ions in the solution.  Electroplating is a process where a metal in solution is deposited onto an electrode that is negatively charged relative to the solution. The item being plated can be referred to as the cathode.  The solution is charged through the use of an anode.   Since the metal in solution is in ionic form and contains a positive charge, it migrates toward the negatively charged cathode.  Once the metallic ion has reached the cathode it picks up the electrons and is deposited onto the cathode (item being plated).  The metallic coating accumulates one atom at at time.  Faraday's law states that for each  Faraday of  electricity (96,5000 Coulombs of electrons), one gram of metal will be deposited on the cathode.  The plating industry uses amperes as the measure of current flowing through the system.  One Ampere = 1 Coulomb of electrons for 1 second therefore it is possible to determine the amount of metal deposited onto the cathode by factoring the amperes by the amount of time the current is flowing. 

 It is important to note that the actual amount of metal deposited by the system is a product of time, the total current flowing through the solution, and bath efficiency; also called the cathode efficiency.  Since bath efficiency can range from less than 10% to more than 90%, it is important to understand the chemistry of the bath to monitor it's efficiency.  For example the metallic content affects the cathode efficiency of our 24K Bright Gold Solution near the range of the stock solution we provide.  Due to cost factors we typically offer this solution with approximately one-third Troy oz fine gold per gallon, (~ 2.8g/qt.).  The depletion table for this solution indicates that increasing the gold content above this level has diminishing effect on the bath efficiency.  However, as gold is depleted from this solution the bath efficiency can fall off significantly. 

There are many factors that affect the properties of the deposit.  A few of the main factors are;  Current density, which is the ratio of the system amperage over the unit area of the anode or cathode.  The temperature of the solution.   The pH of the solution.  The concentration of metallic ions.  Relative movement of the solution and cathode. 
In the future we will be building on the information base on this subject.  We plan to have hyperlinks from various key-words in this section to other sections for more detail.  Please Check Back Again Soon!

Plating With Gold

General Physical Properties of Gold

Atomic Number: 79
Atomic Weight: 196.97
Density: 19.3 grams per cubic centimeter
Melting Point: 1063 C
Boiling Point: 2970 C
Thermal Conductivity: 0.71 cgs units(20 C
Chemically Resistant to: Sulfuric acid (100 C), fuming sulfuric acid, persulfuric acid, fuming nitric acid, 30% hydrochloric acid, perchloric acid, hydriodic acid, phosphoric acid, acetic acid, tartaric acid, citric acid, selenic acid
Chemically Attacked by: Sodium and potassium cyanide plus oxygen, aqua regia, chlorine, chlorine water, bromine and iodine in alcohol, selenic acid (+230C)

Because of its unique physical properties and lasting beautiful color gold has always been one of mans favorite elements. Since the beginning of recorded history gold has served as an art medium and a symbol for wealth, eternity, the Sun, life, love and many other desirable parts of the human experience. Aside from the psychological, metaphysical, and religious appeal of gold it has certain physical properties that make it a desired medium. From the ancient goldsmith to todays scientist, gold is unique in is use.

The process of electroplating gold onto properly prepared conductive surfaces electrochemically deposits a very thin1 layer of metallic gold over the surface of the item to be plated.  This process can impart some of the desired properties of the gold to the entire piece being plated at a fraction of the cost of solid gold.  In many cases you can maintain the important mechanical properties of the substrate and obtain the desirable benefit of an exposed gold surface.  An example of this is gold plating stainless steel or copper electrodes for the fuel cell industry.  In this case you can have the strength or conductive properties of the substrate and the corrosion resistance and/or catalytic, conductive or chemical effect of the gold surface.

1 For a hardened gold plate, (Type I & II - Grade B, C or D),  the gold layer typically ranges in thickness from 5 micro-inches, (0.125m), to 100 micro-inches, (2.55m).  Hard gold plate deposit thicknesses greater than 100 micro-inches can result in deposit stresses that may be detrimental to the value of the gold plating.  Pure soft gold, (Type III, Grade A), Can be plated much thicker.  We commonly plate Type III gold to a thicknesses greater than 500 micro-inches, (12.55m).  The trade off is that the grain structure is more course which allows greater diffusion and generally makes the surface more "matt" in appearance.

The density of 24K gold plating is ~ 12.45mg/in2/5m, (~0.00004 inches) thickness.  Therefore, if evenly distributed, 1 gram of 24K gold will plate approximately 160 square inches of area to a thickness of 1/2 5m, (0.00002" or 20 micro-inches).  This thickness is the minimum thickness of gold plating for jewelry items to be sold as "gold plated" in the United States under the US Federal Trade Commission standards. Note: The density of gold plating can range from 11.3mg/in2/5m through 12.45mg/in2/5m the upper end of the range is for a very fine grain gold plate.

Units for the thickness of gold plate are normally stated in English terms of  "micro-inches", (millionths of an inch,  i.e. 1 micro-inch = 0.000001")  or when Metric terms are preferred then  "microns", (also know as "5m" - "micro-meters" i.e. 15m = 0.000001 meter ), are used.  In discussing the thickness of gold plate the term "micron" is frequently used when  "micro-inch" is the intended unit of measure.  This can create a discrepancy since a micron is about 40 times greater than a micro-inch. 

micron to microinches
provided by www.metric-conversions.org

Less frequently the term "mil" is used when "micro-inch" is intended, this can be a much bigger problem since there are 1000 micro-inches in a mil.  One example of such a problem was recently noticed when a seller at a popular on-line auction was offering 20 gold plated pennies for $4.95.  This is a good deal but then they went on to say "Each coin is specially layered with 7 mils of Genuine Pure 24 Karat Gold".  Using the density information above and a little arithmetic* shows that this seller is offering 1.25 troy ounces of gold for $4.95.  This is not likely since as of this writing the London bullion market was at $1,875.00/troy oz. 

 

*A one mil thickness of 24K gold plate will weight 0.316 grams per square inch.  The surface area of a US penny is ~0.88 square inches.  Therefore - 20pennies * 0.88 in2/penny * 0.316 grams 24K gold/in2/mil thickness * 7mil thickness = 38.93 grams 24K gold.

What is MIL spec Plating?  At Gold Plating Services we provide metal finishing and gold plating for many different customers for many different reasons.  Many of our customers want decorative gold plating and rely on our expertise to provide them with a type and thickness of gold plating that will best fit their purposes and budgets.  We have the experience and expertise to advise them on their options.  Other clients use standard specifications that define many important aspects of the plating process.  For those who aren't sure of exactly what will work best for them we may suggest a specification process that will define the results they need.  We specialize in plating a 24Karat gold to a specific MIL-Spec. (MIL-G-45204-C - recently superseded by MIL-DTL-45204D see below).  Plating gold to these specifications insure that the final product will meet strict purity, thickness, and hardness standards. These specifications also mandate other factors such as undercoating, adhesion and solderability. The specifications also references other MIL and ASTM standards and verification tests. Testing available upon request (additional pricing applied). We apply Mil-Spec plating to items for the aircraft, medical instrumentation industry, and electronics industry. In some cases we are applying a 24K gold plate to various grades of stainless steel and in others, we are plating onto copper, aluminum or brass alloys.  

New MIL-DTL-45204D Gold Plating Specification.  The U.S. Army Research Laboratory has developed a new specification that supersedes the MIL-G-45204C, (dated 7 June 1983), specification referenced above.  The new specification is MIL-DTL-45204D, (dated 29 June 2007), is 24 years more current and addresses questions not adequately covered by the old specification.  The classifications by Type, Grade, Purity vs. hardness, and Class are similar to the old spec, however the new specification includes standardization references to non-governmental and international, (ISO), agreements.  The new specification also has expanded quality control, testing and packaging procedures.  We have this document available as a PDF file for $25.00.  Payment can be made by PayPal or major credit card by e-mail or phone.  We will e-mail the document immediately upon receipt of payment.  For more details click this link - Purchase MIL-DTL-45204D include payment in formation in the e-mail.  We will e-mail a receipt and attach the specification.  Or you can call (801) 546-6200.

Plating Onto Common Metals

We will be continuously adding to this information base on methods of metal finishing and plating onto different types of substrate.  In our gold plating business we plate onto many different types of metal surfaces.  One of our clients has us gold plate coins struck in different substrates. A good example of the type of gold plated coins is the 2000 Presidential Election Coin.  These coins are struck in a bronze copper alloy.  When plating gold onto any copper alloy, such as bronze, we normally plate with a bright nickel prior to   gold plating the coin.  There are two reasons for this nickel plate.  One reason is to provide a diffusion barrier between the copper alloy and the gold plated coin.  This is important because over time, copper can corrode and diffuse through the gold, changing the appearance of the gold.  The second reason for the nickel plate is to enhance the brightness of the finish.  A mirror bright nickel plate will give a high level of luster to the gold plated finish.  We also do selective gold plating onto coins.  When doing selective gold plating onto coins, (or anything else for that matter), we usually mask the area that we don't want to gold plate and then gold plate the coin normally.  The trick in doing selective gold plating coins is to apply the mask in a manner that provides as much detail as possible. An example of selective gold plating on a coin is shown on our Golden Gifts Trading Post.  Selective gold plating onto coins has been very popular with the U.S. Mint's State Quarters program.  We are working with a major mint who has developed an oversized States Quarters.  We are offering these gold plated, State Quarter replicas on our Golden Gifts Trading Post.  They are available in two grades.  A bright un-circulated-circulated, 24K gold plated or German silver (nickel) or LE Proof.  Limited Edition Proof.  The "LE Proofs" are double struck in 1 oz .999 silver and are also available in a 24K gold plate.

Scientific, Technical and Special Purpose Gold Plating

Is gold plating right for your project?

We get a large number of inquires relating to the applicability of gold plating for many different purposes.  The gold plating services we provide fall into three general categories.  The type of plating process we use depends on the customer's specific requirements.  Many times the customer requirements are a combination of the following types of plating.

If you are wondering if gold plating may be right for your needs you may want to refer to the information that follows chronicling clients we serve that have special needs.  If you need more information on the properties of different types of gold plate please feel free to e-mail our technical department with your questions.  terry@goldplating.com

1.     Decorative

A large number of inquires for gold plating we receive are for decorative purposes.  While there are other metals that have the same general appearance as gold, they usually dont offer the same corrosion resistance and combination of physical properties as gold plating.  Gold plating is also very economical as a decorative finish when compared to the other options.  This is especially true when you consider that much of the cost of providing a decorative electroplated finish is incurred in the preparation of the surface prior to the final finish.  An excellent example of this is in jewelry restoration.  The antique copper bracelet we restored, ( http://www.goldplating.com/Bracelet.htm ),  required hours of tedious labor to prepare the bracelet for plating, this is where most of the cost was incurred.  The actual value of the gold we applied was just a few dollars.  However, as far as the owner was concerned it turned a piece of useless jewelry into a valuable heirloom that will be passed on for generations.  Generally speaking, the cost of decorative gold plating is ranges from $2.00 - $3.00 per square inch (.25m to .55m thick).  This would not include any unusual finishing, restoration, special handling or pretreatment.  Of course the price also is dependant on other factors such as quantity, size and special tooling that may be required.

Many people are rightly concerned about the softness of 24K gold for decorative applications.  We recognize the limitations of all electrodeposited finishes and strive to give the customer the best information possible for making a choice that is the most suitable for their purposes.  There have been many times when we have indicated that gold plating is not appropriate for a particular purpose and have helped the customer decide on a different choice.  For decorative gold applications, we normally recommend a cobalt hardened 24 karat gold.  This gold is a 99.7% pure gold, is extremely corrosion resistant, and is about three times as hard as the pure gold we use for medical, electronic and other applications where hardness isnt required and purity of deposit is.

2.     Corrosion resistance

Because of the relative low cost and high resistance to many corrosive environments, we provide a great deal of gold plating that has the primary purpose of providing corrosion resistance to a substrate that otherwise would quickly corrode, such as copper.  This need arises quite often because the desirable electrical properties of copper is quickly diminished by the reactive nature of the copper surface.  While gold is not as conductive as most copper  or silver, gold does provide much better resistance to corrosion than either metal.  Hence, we often provide a gold plate over a copper or silver substrate.  An excellent example of using gold plating as a corrosion resistant barrier for a copper substrate is found on our home page.  The RF load coil shown is a key component of an inductively coupled plasma mass spectrometer, (ICP-MS).  These coils operate in an extremely harsh environment under high temperatures, and have to withstand high frequency electrical current without significant degradation of the surface.  The scientist who developed, and patented these high performance, corrosion resistant coils had tried different combinations of transition elements before settling on this particular process which involves   the application of an extremely heavy pure gold electroplate over a copper substrate with a transition element diffusion barrier. 

Even a bright, hard gold plate is somewhat porous; therefore when the gold is applied over a substrate that poses the possibility of diffusing through the gold, such as silver or a copper alloy, we normally suggest a transition element diffusion barrier such as nickel, rhodium or palladium.  This will help insure that the substrate is protected against the environment.  We provide gold plating services for some high-energy research laboratories that specify the deposit must not be magnetic.  Since most nickel deposits are magnetic to varying degrees this precludes the use of nickel as a diffusion barrier.  In this case we usually recommend increasing the thickness of the gold plate to a level that prevents significant diffusion under most conditions, (25m is generally sufficient), or using a platinum group element such as rhodium or palladium.  The new MIL-DTL-45204D references gold plating as a chemical agent resistant coating, (CARC).

3.     To provide physical properties unique to gold such as reflectivity or conductivity.

We have many research and development labs contact us about gold plating for their projects because of some of the other known properties of gold plating.  One such contact was a company developing a medical laser.  The gold plating they required was for excellent reflection throughout the electromagnetic spectrum from visible through near-IR (e.g. up to 820nm and specifically 808nm, the most important wavelength for Nd:YAG lasers).  They indicated measurements on our plating in excess of 97% reflection throughout this spectrum.  Since they were looking for a reflector that works in the 808nm range, gold was the perfect choice for their project.  The reflectors were a 316 stainless steel, we provided 15m of hardened gold applied directly to the polished stainless steel surface.

We have another client that produces equipment that utilizes a component that operates in such a harsh environment that nothing they had tried would prevent the item from literally burning up in just a few hours.  Our technical staff worked with their development engineers to find a solution that utilized a pure nickel substrate followed by a heavy (25m+) pure rhodium plate with 55m of a 999+% gold deposit.  The components produced utilizing this very specialized process have preformed for months of extreme, continuous testing.

4.  Gold Plating Stainless Steel items with or without a nickel underplate?  We specialize in gold plating onto stainless steel items for a variety of technical and decorative purposes.  The question of using a nickel underplate when plating gold onto stainless steel frequently comes up.  Here is an opinion letter regarding nickel underplate for stainless steel that was written by one of our technical advisors.  Nickel Underplate When Gold Plating Stainless Steel

 

Because of its inert chemical properties, versatility of application and relatively low cost, electroplating of gold has proven to be the answer to many engineering and technical problems.

 

 

 

 











Frequently Asked Questions

(Q) .. Is it really possible to make money with a portable gold plating business?
(A) .. Absolutely, we have many customers that started their portable gold plating business on a part time basis with little more than a cell phone and the components that initially came in their original electroplating kit.  With a service oriented attitude and some persistent work, they have grown it into an excellent income.  Others have kept is as a part time "extra income" business only plating a few cars a month.  Because there is virtually no fixed overhead, it works perfectly as a part time business.  Follow this link for more information on making money with a gold plating business.

(Q) .. I work in an auto auction & am in a parking lot every day & inspecting emblems. I honestly don't know a gold plated emblem from a gold colored plastic yet. I've seen several that are darkened and others that look as if they have black bubbles through out. Would these be simply plastic or poorly applied gold?  

(A) .. Probably both.  Most automotive emblems are plastic and most of the emblems that look gold, (in good or bad condition), are plastic emblems that have been gold plated.  The reason that the bad looking gold looks bad is most likely the result of being plated with a "short cut" method of gold plating or they were plated by someone that wasn't concerned about the quality of their work.  We are trying to head off this image in our industry by promoting high quality workmanship, not just going for the fast buck now.  We do this by only promoting the most durable process of automotive gold plating, i.e. chrome removal and applying the gold heavy enough to insure corrosion protection to the underlying nickel.  Any gold plated layer is relatively thin and somewhat porous.  If the gold layer isn't thick enough to seal off the underlying nickel plate then corrosive environmental conditions can corrode the nickel plate.  When the nickel plate corrodes, it first forms tiny black pits.  The black pits develop into small mounds that look something like a miniature volcano when magnified.  These mounds are caused by the corroded nickel expanding under the surface.  From a distance this nickel corrosion can appear  as a general darkening of the emblem.  When the nickel gets to this point, the emblem most likely needs to be re-plated with nickel and is probably not worth saving.  At Gold Plating Services, we have always offered a lifetime warranty on our automotive gold plating.  We guarantee that the gold we apply plate won't peel, flake, or corrode for the life of the car.  We promote a process that allows this type of warranty.  By the way, there are a few vinyl automotive "emblems" (I call them decals) that are suppose to look like gold, they are soft and will indent if you push on them with your thumbnail.

(Q) .. I've heard that the thickener used to convert liquid brush plating gold to a gel reduces the amount of actual gold solution I receive by up to 1/3. Does your gold thickener add to the volume of gold?
(A) .. NO, the thickener we use is a very fine powder. The amount required to thicken an 8oz jar of gold actually increases the total volume of the solution by less than 2%. We compensate for the added volume by slightly overfilling the jar. When you buy the solution you are actually buying the pre-thickened volume. We do, however have some customers that prefer to buy the solution as a liquid and the thickener on the side. They then add the thickener to suit their personal preference.

(Q) .. Why is aluminum so difficult to plate?
(A) .. Aluminum is a very reactive metal.    After being polished or cleaned the surface oxidizes within seconds of coming into contact with the air. The resulting thin layer of aluminum oxide is very inert, coherent, and protective and cannot be reduced (returned to the pre-oxidized state) electrolytically. The oxide layer cannot be plated onto. One typical method used to plate onto aluminum involves removing the oxide layer using a strong alkaline solution which simultaneously replaces the oxide film with a layer of zinc (known as zincating). The zincated part can then be plated with an electroless nickel or alkaline copper solution. The part can then be plated normally. The use of the extremely caustic zincate solution and hot dip electroless nickel solution makes plating onto aluminum impractical for most portable platers using standard electroplating kits. Many larger chrome shops can economically plate a heavy coat of hot-dip decorative nickel onto aluminum. This will produce a very hard mirror bright surface that then easily be gold plated. While it is possible to plate onto aluminum using a portable system, the process is not cost effective and the durability of the resulting finish is generally not sufficient for long term service. When we have a customer that wants an aluminum part gold plated we always recommend a procedure that involves a hot-dip nickel layer.

(Q) .. Would your machines work to repair chrome for hotrod/muscle car enthusiasts? Would the pieces need to be completely stripped down or could  chrome be applied in these scratched/"injured" areas? 

(A) .. Our system will repair chrome as well or better than any portable system on the market.  However, I like to give people an honest answer to the chrome repair question.  You need to understand that chrome is normally plated over a heavy, hot dip immersion nickel that produces a lot of thickness relative to the chrome plate.  The heavy nickel plate is plated over a heavy copper plate.  Therefore, offering a "chrome plate repair" without being able to also repair the underlying copper and nickel is a little like trying to fix a dent in a fender by simply applying a thin layer of paint.  While it is possible to sand out the ding, plate with copper, polish, plate with nickel, polish and then plate with chrome this repair would require a lot of time and a high level of craftsmanship, and almost never would be worth the effort.  This is especially true in light of the fact that a large chrome shop will straighten, strip and completely re-plate an entire bumper for a couple of hundred dollars.  There are well established, large chrome plating businesses that have invested millions of dollars in chrome plating equipment.  These companies such as Ogden Chrome Plating, provide an extremely high level of service for a relatively low price.  It is our opinion that it is not smart for a person with a portable plating system or a home based (bucket) chrome plating system to compete with these well established companies.  This is epically true when the environmental regulations and procedures for disposal of rinse water and spent solutions is taken into account.   There are far more profitable ways to utilize a portable gold plating system.  In fact, I have never heard of anyone that has made a profit offering portable automotive chrome repair.


(Q) .. How can I tell if a conductive surface is chrome, aluminum, or stainless steel?
(A) .. Most silver colored, metallic (conductive), surfaces encountered in everyday use are either chrome, stainless steel, aluminum, nickel, zinc or silver.
If you are faced with a surface and don't know what it is. By using our portable plating system, you can determine which of the above four it is by grounding the part and touching the surface with your chrome stripping wand. If it is chrome plated there will be a distinct yellowing of the chrome stripping solution. Careful analysis of the surface after you have worked on it with the chrome wand will reveal a slightly darker, bright metallic surface, (the nickel) as opposed to the chrome that has more of a blue tint. If the item is stainless steel, you should be able to detect some light, bubbling action where the wand is in contact with the surface. The stripping process won't have any affect on the appearance of the surface, however the solution may develop a light purple tint. An aluminum part may initially react like stainless steel. The chrome stripping solution will lightly attack the surface of the aluminum, when you have moved the wand away from the surface there may still be some light bubbling where the solution was left on the part. After rinsing, the area that you tried to strip may be slightly milky white and with less luster. Normal polishing with metal polish will return the surface to its previous condition. Since polishing may be required on aluminum items, it is recommended that you try a very small area on items that could be aluminum. Silver surfaces will immediately turn black when you try to strip them with the chrome stripper. Don't worry, the nickel activator will remove the smut. Zinc parts won't have any reaction to the stripper, but the nickel activator will attack the zinc surface even without having the common applied. If you then try to gold plate a zinc part using our normal gold solution, the part will turn black.

(Q) .. Why do I need to use a nickel strike on stainless steel?
(A) .. Stainless steel, is a family of steel alloys that contain, among other things, 15% to 20% chromium.  The chromium is a little like aluminum in that it forms a thin, self-healing layer of chromium oxide. The chromium oxide is inert and therefore highly corrosion resistant and difficult to plate onto. Fortunately, unlike aluminum oxide, the chromium oxide can be chemically reduced using an acid solution. If the acid solution contains nickel, such as the Woods Nickel Strike that comes in our electroplating kits, the reduced chrome can then be simultaneously plated with the nickel in the strike. The part can then be activated and plated normally. Remember that a key step in our stainless procedure is to abrasively remove the all of the oxide layer possible prior to the nickel strike step. Since we have had so many questions on the stainless procedure, I have revisited our published stainless procedure and amended it. I have taken out the nickel prep step, which is only necessary under extremely oily conditions. Click here for the stainless steel procedure

(Q) .. Does an automobile emblem have to be removed before it can be gold plated.
(A) .. Not usually, our electroplating kit utilizes a unique process has been developed to allow the technician to leave the emblem on the car in almost every case. The plating solutions will not affect most new car finishes. Our training will teach you how you can tell if there could be a risk of having a problem with leaving an emblem on the vehicle. Being able to leave the emblems on the vehicle provides a great advantage for the on-site plater. Imagine the cost of removing the emblems, sending them to a plating company and then having to re-install the plated emblems, and then having to re-install the plated emblems.

(Q) .. How long will the gold last ?
(A) .. 24 Karat gold will never corrode under normal conditions.  The plating that is applied with our system is the same as any other 24 karat gold electroplate, no more or less. While 24 Karat gold will never corrode under normal conditions and if applied correctly should never peel, flake or fade it is very soft and needs to have proper care to insure maximum life.
