Gold plating is a method of depositing a thin layer of gold onto the surface of another metal, most often copper or silver (to make silver-gilt), by chemical or electrochemical plating. Plating refers to modern coating methods, such as the ones used in the electronics industry , whereas gilding is the decorative covering of an object with gold ...
The abbreviation EPBM on such items denotes "electroplated Britannia metal". Britannia metal was generally used as a cheaper alternative to electroplated nickel silver (EPNS) which is more durable. Until 2016, britannium was used to make the solid core of the Oscar statuettes. The 8½ lb (4 kg) statuettes were Britannia metal plated with gold. [6]
Electroplating, also known as electrochemical deposition or electrodeposition, is a process for producing a metal coating on a solid substrate through the reduction of cations of that metal by means of a direct electric current. The part to be coated acts as the cathode (negative electrode) of an electrolytic cell; the electrolyte is a solution ...

If the gold layer is 12 kt or higher, the minimum layer of karat gold in an item stamped gold-filled marks must equal at least 1 ⁄ 20th the total weight of the item. The most common stamps found on gold-filled jewelry are 1 ⁄ 20th 12kt GF and 1 ⁄ 20th 14kt GF. Also common is 1 ⁄ 10th 10kt. These standards are for modern gold-filled items.

Electroless nickel immersion gold. Electroless nickel immersion gold ( ENIG or ENi/IAu ), also known as immersion gold (Au), chemical Ni/Au or soft gold, is a metal plating process used in the manufacture of printed circuit boards (PCBs), to avoid oxidation and improve the solderability of copper contacts and plated through-holes.
