Method for non-cyanide copper electroplating of steel parts

The invention discloses a method for non-cyanide copper electroplating of steel parts, which relates to a method for copper electroplating of the steel parts. The method solves the problems that cyanide is easy to pollute air and water sources, can be naturally oxidized in plating baths, is oxidized on electrodes and has quick consumption and high cost. The method for the non-cyanide copper electroplating of the steel parts is realized according to the following steps of oil removal, non-cyanide copper leaching and copper electroplating, and thus the steel parts with electroplated copper are obtained. The steel parts with the electroplated copper prepared by the method have unpeeled plating layers, do not blister, and have good bonding force after high-temperature treatment. The method has simple process and convenient operation.
