Aluminum and its alloy surfaces are prone to forming a thin oxide film when exposed to fluorine, but due to the porous and amorphous nature of the film, it cannot serve as a reliable protective layer, and the surface glossiness is poor. The aluminum alloy anodizing power supply series can solve this problem. It can produce a dense oxide film on the surface of aluminum alloy, increasing its corrosion resistance, wear resistance, and decorative properties. On this basis, coloring should be used to make aluminum alloy more practical and decorative, which should be more extensive.
