WebElectroplating is a process by which a metal is deposited on any other metal by passing current in the electrolyte. The basic principle is the electrolysis, i.e. the decomposition of the electrolyte used. The material to be deposited is made as anode and where deposited as cathode. For electroplating the d.c. low voltage is used upto 25 V or so. WebThe plating tanks typically are equipped with some type of heat exchanger. Mechanical agitators or compressed air supplied through pipes on the tank bottom provide uniformity …
