[0003] One of the most commonly used surface treatment methods is the traditional anodizing method, which uses aluminum alloy as an anode in an acidic solution to form a dense oxide film under the action of a DC electric field, thereby enhancing its corrosion resistance. In addition, there is also a method of using chemical conversion coating, which forms a protective layer by applying specific chemicals to the surface of aluminum alloy. Although these two methods can improve the corrosion resistance of aluminum alloy to a certain extent, they also have certain limitations.
