[China Aluminum Network] aluminum titanium plating process, which belongs to the coating technology, it is based on the conventional titanium plating process to increase the pre-plating and plating process steps, pre-plating process is to put the activated plating parts in salt and hydrochloric acid The chemical treatment is performed in an aqueous solution; the plating solution of the electroplating process includes nickel sulfate, nickel chloride, boric acid, sodium lauryl sulfate, saccharin, brightener, and the process is simple, practical, and has good effects, and is obtained by this process. Titanium aluminum profiles have a film hardness of HV ≈ 1500 and a wear resistance of 150 times that of 22K gold plated under the same conditions. They can be processed into gold, color, black and other bright aluminum products in various forms.
Titanium-plated aluminum process, including material selection, polishing, chemical deoiling, water rinse, activation, vacuum titanium plating process steps, is characterized in that it also includes:
a. Pre-plating process. The process consists of placing titanium aluminum profiles activated and rinsed with clean water in a liquid consisting of salt, hydrochloric acid and water for chemical treatment. The processing temperature is room temperature, and the processing time is violent to the liquid. Up to; b, electroplating process, the bath composition includes nickel sulfate, nickel chloride, boric acid, sodium lauryl sulfate, saccharin, brightener, process conditions: current 3-4A/dm2 cathode movement, 5-7A /dm2 air stirring, bath temperature 50-60°C, PH value 3.9-4.2, plating time 15 minutes.
