Background

Electroplating is a process of plating a thin layer of other metals or alloys on the surface of some metals by using the principle of electrolysis, and is a process of attaching a layer of metal film on the surface of a metal or other material product by using the action of electrolysis so as to play roles of preventing metal oxidation, improving wear resistance, conductivity, light reflection, corrosion resistance, enhancing appearance and the like. The outer layer of many coins is also plated. During electroplating, plating metal or other insoluble materials are used as an anode, a workpiece to be plated is used as a cathode, and cations of the plating metal are reduced on the surface of the workpiece to be plated to form a plating layer. In order to eliminate the interference of other cations and make the coating uniform and firm, a solution containing the metal cations of the coating is used as an electroplating solution to keep the concentration of the metal cations of the coating constant. The purpose of electroplating is to plate a metal coating on a substrate, altering the surface properties or dimensions of the substrate.
