The aluminum plating process, which belongs to the coating technology, is to increase the process of pre plating and electroplating on the basis of conventional titanium plating. The process of aluminum profiles is treated by chemical treatment of the activated plating in the water solution of salt and hydrochloric acid.
The plating bath consists of nickel sulfate, nickel chloride, boric acid, twelve alkyl sulfate, saccharin and brightener. This process has the advantages of simple, practical and good effect. The coating hardness of the titanium and aluminum profile made by this process is HV 1500, and under the same condition, the wear resistance is 150 times more than the 22 K gold plating. It can be processed into various forms of gold, color, black and other bright series of aluminum products.
