ã€China Aluminum Industry Network】Aluminum titanium alloy plating process belongs to the coating technology, which is based on the conventional titanium plating process to increase the pre-plating and plating process steps. The pre-plating process is to place the activated plating member in an aqueous solution of salt and hydrochloric acid for chemical treatment; the electroplating process includes nickel sulfate, nickel chloride, boric acid, sodium lauryl sulfate, saccharine, brightener, etc. The process has the advantages of simplicity, practicality, and good effect. The titanium aluminum film produced by this process has a film hardness of HV ≈ 1500 and is wear-resistant 150 times higher than the 22K gold plated under the same conditions and can be processed into various forms of gold. Color, black and Other bright variety of aluminum products.
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:
First, the pre-plating process, the process is activated and washed with water after the titanium aluminum profiles placed in salt, hydrochloric acid and water in a liquid chemical treatment, the processing temperature is room temperature, processing time to the liquid chemical reaction until;
Second, the electroplating process, the plating bath components include 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.
