In order to enhance corrosion resistance and wear resistance of the aluminum cover during manufacturing, the subsequent adsorption of dyes and colored substances on the aluminum cover is facilitated, and the aluminum cover is usually required to be anodized after polishing is finished. The anodic oxidation of aluminum is generally carried out in an acidic electrolyte, with aluminum as the anode. During electrolysis, oxygen anions react with aluminum to produce an oxide film. The film is not fine enough when initially formed, and the negative oxygen ions in the electrolyte can still reach the aluminum surface to continuously form an oxide film although the film has a certain resistance. As the film thickness increases, the resistance also increases, and the electrolytic current becomes small. At this time, the outer oxide film in contact with the electrolyte is chemically dissolved. When the rate of oxide formation on the aluminum surface is gradually balanced with the rate of chemical dissolution, the oxide film reaches a maximum thickness at this electrolysis parameter. The outer layer of the anodic oxide film of aluminum is porous and is easy to adsorb dyes and colored substances, so that the anodic oxide film can be dyed, and the decorative property of the anodic oxide film is improved.

The aluminum cover is arranged on the mounting frame during the existing aluminum anodic oxidation, and then the mounting frame is placed in an electrolytic tank filled with electrolyte. In the anodic oxidation treatment process of the aluminum cover, the aluminum cover is placed in the electrolytic tank in a static mode, and the concentration of the electrolyte at different positions or even different heights is different along with the increase of the service time, so that the current density is different, the thickness and the shape of an oxide film formed on the aluminum cover are uneven, and the corrosion prevention effect of the surface of the aluminum cover is different.
