Electroplating process
Electroplating is a process in which a metal film is attached to the surface of metal or other materials by electrolysis. Can play a role in preventing corrosion, improving wear resistance, electrical conductivity, reflective and improve the appearance. Electroplating with conductive surface of the plated parts as the cathode, plating metal or insoluble materials as the anode, the immersion containing coated metal ions in the electrolyte, through direct current, the plating parts on the deposition of coated metal process known as electroplating, the principle is in the Yang, cathode on the electrochemical oxidation and reduction reaction. The coating metal or other insoluble material is the anode, the workpiece to be plated is the cathode, and the cation of the coating metal is restored on the surface of the workpiece to be plated to form the coating. In order to eliminate the disturbance of other cations, and make the coating uniform, strong, need to use a solution containing metal cations electroplating solution.
