Gold plated sometimes called electroplated items are made with a layer of gold on the surface over another type of metal underneath. Gold Plating / Electroplating is the process of coating one metal or metal object with a very thin layer of another metal, typically by applying a direct electric current. This partially dissolves the metals and creates a chemical bond between them. The coating applied by electroplating is usually around 0.0002 inches thick.
Modern gold plating, called gold electroplating, relies on a chemical process to combine various layers of metal into a solid piece with a layer of gold resting on the surface. Gold Plating Services have been in use commercially since the 1840s and was heavily refined during the two World Wars.
In all gold plating, the part is polished and cleaned as thoroughly as possible before the electroplating process starts. Gold plating will look uneven and smudged if the surface is dirty, oily, scratched or otherwise damaged.
Gold Plating can be added to almost any metal, including brass, copper or nickel. Silver items can also be gold-plated. Some pieces will actually be plated with a wide range of metals even if you can only see the gold plating. If you have a silver component, for example, it will first be plated with copper because copper will make the plating tarnish slower. Then a plate of nickel will be added to improve the bond and strengthen the barrier.
