Embodiment 1
[0073] A method for multi-arc ion plating silver film on the surface of a brass faucet, comprising the following steps:
[0074] (1) Pretreat the surface of the polished brass faucet, and preheat the pretreated brass faucet at a temperature of 45°C;
[0075] (2) Spray the silicone primer on the surface of the brass faucet, make the silicone primer self-leveling and dry for 25 minutes, heat it to 80°C and keep it for 2 hours, then raise the temperature to 145°C and keep it for 40 minutes. The silicone primer is Hydroxy acrylic silicone coating, wherein the thickness of the silicone primer spray coating is 20 μm;
[0076] (3) Place the brass faucet treated in step (2) in the coating box, place the chromium target in the coating box, vacuumize the coating, and then apply multi-arc ion plating to the brass faucet in the coating box. Coating is carried out by means of bias voltage plus magnetron sputtering coating, and argon gas is passed into the coating box during the coating pr...

[0080] A method for multi-arc ion plating color film on the surface of a brass faucet, comprising the following steps:
[0081] (1) After the surface of the finely polished brass faucet is pretreated by dedusting, ultrasonic cleaning, degreasing and drying, preheat the dried brass faucet at a temperature of 60°C;
[0082] (2) Spray the silicone primer on the surface of the brass faucet, make the silicone primer self-leveling and dry for 30 minutes, heat to 82°C and keep it for 1.5h, then raise the temperature to 150°C and keep it for 40min, the silicone primer It is a hydroxyacrylic silicone coating, wherein the thickness of the silicone primer sprayed is 15 μm;
[0083] (3) Place the brass faucet treated in step (2) in the coating box, place the titanium target in the coating box, vacuumize the coating, and then apply multi-arc ion plating to the brass faucet in the coating box. Coating is carried out by means of bias voltage plus magnetron sputtering coating, and oxygen is ...
Embodiment 3
[0087] A method for multi-arc ion plating gold film on the surface of zinc alloy handle and brass faucet, comprising the following steps:
[0088] (1) Pretreat the zinc alloy handle and the surface of the brass main body after fine polishing, and preheat the pretreated blank, and the preheating temperature is 30°C;
[0089] (2) Spray the silicone primer on the surface of the blank, make the silicone primer self-leveling and dry for 35 minutes, heat it to 78°C and keep it for 2.5h, then raise the temperature to 155°C and keep it for 40min, the silicone primer is Hydroxy acrylic silicone coating, wherein the thickness of the silicone primer spray coating is 25 μm;
[0090] (3) Place the blank processed in step (2) in the coating box, place the titanium target in the coating box, vacuumize the coating, and then apply multi-arc ion coating to the blank in the coating box to apply bias Magnetron sputtering coating is added, and nitrogen gas is introduced into the coating box durin...
