Titanium aluminum production technology

Aluminum titanium gold craft belonging coating technology, it is to increase pre-plating and electroplating process steps in the conventional process based on titanium, pre-plating process is placed plating solution and hydrochloric acid salt is chemically treated activated after; Plating bath composition include nickel sulfate, nickel chloride, boric acid, sodium lauryl sulfate, saccharin, brightener, the process is simple, practical, good effect, etc., the process obtained its titanium foil aluminum film hardness HV≈1500, under the same conditions than wear and 22K gold-plated 150 times, can be processed into various forms of gold, color, black and other bright variety series aluminum products.

Aluminum titanium gold process, including selection, polishing, chemical degreasing, rinse, activation, titanium vacuum process steps, characterized in that it comprises:

a, pre-plating process which is activated after the rinse by the titanium grade 2 sheet and aluminum to liquid by the salt, hydrochloric acid and water in the chemical treatment, the treatment temperature is room temperature, the processing time to a heated liquid chemical reaction so far;

b, plating process, the process bath composition comprising nickel sulfate, nickel chloride, boric acid, sodium lauryl sulfate, saccharin, brighteners, process conditions: current 3-4A / dm2 cathode move, 5-7A / dm2 air mixing, bath temperature 50-60 ℃, PH value of 3.9-4.2, plating time of 15 minutes.
