Background

The electroplating process is a method for laying a layer of metal on a conductor by utilizing the principle of electrolysis. Electroplating is a surface processing method in which cations of a pre-plated metal in a plating solution are deposited on the surface of a base metal by electrolysis using the base metal to be plated as a cathode in a salt solution containing the pre-plated metal to form a plating layer. The plating performance is different from that of the base metal, and has new characteristics. The coating can be divided into protective coating, decorative coating and other functional coatings according to the functions of the coatings. 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.
