Aluminum profile titanium gold plating process, 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 the activation of the plated parts are placed in an aqueous solution of salt and hydrochloric acid for chemical treatment; plating process of the plating solution components include nickel sulfate, nickel chloride, boric acid, sodium dodecyl sulfate, saccharin, brightener, the process has a simple, practical and effective, etc., the advantages of the process This process has the advantages of simplicity, practicability and good effect, etc. The titanium aluminum profiles produced by this process have a film hardness of HV ≈ 1500, which is 150 times more wear-resistant than 22K gold-plating under the same conditions, and can be processed into a variety of forms of gold, color, and black and other bright series of aluminum profile products.

a, pre-plating process, the process is activated and rinsed with water titanium gold aluminum profiles placed in a liquid consisting of table salt, hydrochloric acid and water for chemical treatment, the treatment temperature is room temperature, the treatment time until the liquid undergoes an intense chemical reaction;

b, plating process, the process of plating solution composition including nickel sulfate, nickel chloride, boric acid, sodium dodecyl sulfate, saccharin, brightener, process conditions: current 3-4A / dm2 cathode movement, 5-7A / dm2 air agitation, plating temperature 50-60 degree , PH value 3.9 -4.2, plating time 15 minutes.
