Titanium aluminum profile production technology

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.

Aluminum profile titanium plating process, including material selection, polishing, chemical degreasing, water rinsing, activation, vacuum titanium plating process steps, characterized by it also includes:

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 ℃, PH value 3.9 -4.2, plating time 15 minutes.
