What is Gold Plating? The 12 Key Things to Know
Brief Explanation of what gold plating is
Gold plating applies a layer of gold onto a base metal or substrate. This technique commonly produces gold-plated jewelry, such as necklaces, earrings, and bracelets. It is possible to apply the layer of gold in different ways. One standard method is electroplating, which involves using an electric current to deposit the gold onto the surface.
The thickness of the layer is measurable in microns, with a higher number indicating a thicker layer of gold. Gold plating improves the appearance and durability of plated jewelry, protecting it from Tarnish and wear. Sterling silver is a popular base metal for gold-plated jewelry, and 18k gold is a standard plating layer.
The 12 Key Things to Know about Gold Plating
The following are a few things that need consideration when considering gold plating.
Explanation of how the gold plating works
The gold plating process involves a series of steps that ensure a clean and smooth surface for the metallic coating. Firstly, the character must clear any impurities or unwanted materials through sandblasting or any other appropriate method.
Next, the surface requires cleaning using a degreasing solution. Then rinsed thoroughly to ensure the surface is free from dirt and residues. Later, a strike solution applied to the cover helps improve the gold adhesion to the surface. After that, the covering rinses again to remove any excess chemicals.
A base coat comes in contact with the surface, acting as a final coating primer. Finally, the character gets a coating of a thin layer of actual gold. Then it gets a rinse one last time to ensure that the plating evenly applies and no residue is left behind. The gold makes the plating process result in a striking and durable finish that resists rust and tarnish. The execution of these series of technical steps brings precision to ensure a flawless result.
Most importantly, the electrical current passing through the solution causes the gold to adhere to the object's surface, called electrodeposition. Finally, the thing needs polishing to achieve a high gloss finish so it last much longer. The gold-plating process requires expert knowledge and precise execution to achieve a high-quality result.

What Metals Does Gold Plating Work With?
The process of gold plating works with various metals, such as stainless steel, copper, brass, and even nickel. However, the effectiveness of the coating depends on the composition of the substrate surface. For example, copper is a good candidate for gold Plating because it is highly conductive and has a uniform consistency.
On the other hand, nickel is more challenging to the plate. It tends to oxidize and form a passivating layer, which hinders the adhesion of gold. Therefore, unique pre-treatment processes, such as etching, activation, or de-passivation, may be necessary to achieve a durable and aesthetically pleasing result.
How Much Gold Is Part of the Plating?
The amount of gold used in plating varies depending on the desired thickness and overall purpose. In addition, different plating methods, such as electroplating and electroless plating, use different gold amounts.

Quality of gold used in plating
A plating thickness of 2.5 microns is a significant part of the jewelry industry. This thickness deems sufficient for most jewelry, making it a popular choice among manufacturers. Gold ions help in plating. The coating quality reflects through the number of ions added to the plating solution. With a 2.5-micron thickness, jewelry protects from wear and tear while maintaining its appearance.
Even with everyday use, this thickness quality is durable enough to keep jewelry looking beautiful for a long time. As a result, this provides the ideal balance of durability, quality, and beauty in the products.
The colour of the plating
The colour of the plating serves an aesthetic purpose and indicates the type of material used for this process. The plating thickness of the metal can alters the colour depiction. The thicker the chrome plating layer, the darker and more mirror-like finish it will have. Conversely, the thinner the plating, the brighter the metallic appearance the surface will have.
Some gold coating processes use a colouration treatment. It is to achieve hues like gold or black, which add a specific design element to the product. Hence, choosing the right colour for plating can significantly enhance product functionality, durability, and marketability.
Types of Processes used in Gold Plating
There are five classes of gold plating chemistry, each with unique methods and applications. The first is immersion coating or electroless plating, where a chemical reaction deposits gold onto a substrate. The second is electroplating, which involves passing an electric current through a metal solution to the plate onto the substrate.
Moreover, the third is pulse electroplating. This plating uses high-current pulses to the metal solution to deposit the metal rapidly. The fourth is vacuum deposition, which involves vaporizing the gold and depositing it onto the substrate in a vacuum chamber.
The final class is brush plating. It involves using a specialized brush to deposit a thin layer of gold onto a specific substrate area. The process of the gold plating has its benefits and limitations. The selection of which depends on the particular application requirements.
