Galvanic plating
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 of a salt of the metal to be coated; and the anode (positive electrode) is … WebAug 17, 2024 · Galvanic plating also called electroplating or galvanization, means coating some base metals with other metals.In our case, it is coating silver with gold, rhodium and platinum.This process is mainly intended to protect the silver items against blackening, but also to add them decorative values.
