Titanium gold plating process for aluminum profiles belongs to the coating technology. It adds pre-plating and electroplating process steps on the basis of the conventional titanium plating process. The pre-plating process is to place the activated plated parts in an aqueous solution of common salt and hydrochloric acid for chemical treatment; The plating solution components of the electroplating process include nickel sulfate, nickel chloride, boric acid, sodium lauryl sulfate, saccharin, and brightener. This process has the advantages of simplicity, practicality, and good effects. The titanium gold aluminum profile produced by this process has The film hardness is HV≈1500, and it is 150 times more wear-resistant than 22K gold plating under the same conditions. It can be processed into various shapes of gold, color, black and other bright series of aluminum profiles.
Aluminum profile titanium plating process, including material selection, polishing, chemical degreasing, water rinse, activation, vacuum titanium plating process steps, characterized in that it also includes:
a. Pre-plating process. This process is to place the activated titanium gold aluminum profile in a liquid composed of table salt, hydrochloric acid and water for chemical treatment. The treatment temperature is normal temperature. The treatment time is until the liquid undergoes a violent chemical reaction. until;
b. Electroplating process. In this process, the components of the plating solution include nickel sulfate, nickel chloride, boric acid, sodium lauryl sulfate, saccharin, and brightener. Process conditions: current 3-4A / dm2 cathode movement, 5-7A / dm2 Stir with air, the temperature of the plating solution is 50-60 ℃, the PH value is 3.9-4.2, and the plating time is 15 minutes.
