company news about What are the steps of the coating method on the surface of aluminum alloy wheels?

The company has developed a method for coating the surface of an aluminum alloy wheel, which includes the following steps: S1. grinding and polishing the aluminum alloy wheel; S2. cleaning the aluminum alloy wheel; S3. immersing the aluminum alloy wheel in a titanium fluoride/zirconium fluoride solution to form the surface Al2O3.ZrO2.TiO2 conversion film; S4. The surface of the aluminum alloy wheel is treated by the radio frequency ionization concentration of 99.999% oxygen to form oxygen ions; S5. The magnetron sputtering coating is added while adding acetylene gas; S6. Baking and curing, the coating has better corrosion resistance, low cost, low energy consumption, and does not contain toxic metals such as hexavalent chromium, and the process is green and environmentally friendly.
