ABSTRACT:
A method of plating aluminum parts is disclosed, which provides improved adhesion of the plated system with decreased restraints on transfer time between steps. The aluminum part must contain 1-8% alloyed zinc and be cleaned to be free of grease and organic contaminants, such as by the use of alkaline and etching cleaners. The part is then cathodically cleaned employing sulfuric acid, to be free of any oxide film. While in the latter condition, cyanide and borate salts are cathodically deposited (Ph 7.5-10.5) permitting increased transfer time, up to 1 hour, before metal plating. The salt coated part is immersed in an electrolytic cell to displace the salt coating with a bronze strike containing 58-88% tin. Finally a lustrous decorative coating system is plated thereover.
