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 workpiece by using the action of electrolysis so as to prevent the metal from being oxidized (such as corrosion), improve the wear resistance, conductivity, light reflection property, corrosion resistance (such as copper sulfate and the like) and enhance the appearance, and the like. 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.
