Aluminum alloy is the most widely used non-ferrous metal structural material in industry and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries.
It is easy to form an extremely thin aluminum oxide film on the surface of aluminum alloy. This oxide film is loose, porous, uneven, has weak corrosion resistance, and is prone to stains.
Therefore, aluminum alloy products usually undergo special oxidation treatment. Before the curing treatment, the surface of the product is cleaned as necessary using chemical and physical methods to expose the pure metal matrix to facilitate the smooth progress of oxidation and coloring, thereby obtaining the same An artificial membrane that has a strong base bond, meets the requirements in color and thickness, and has the best corrosion resistance, wear resistance and other good properties.
