In this paper, we report the change of Al concentration in the baths with increasing anodized area in the production practice, and the effects of Al dissolved in the electrolyte on the anodizing process and the properties of anodized film. The results of experiments are as follows,
(1) The increase of Al content in the baths is proportional to the anodized area.
(2) The electric conductivity of electrolyte decrease with increasing Al concentration of the electrolyte, but in anodizing process the electrolyte contain minut Al show max conductivity.
(3) The data of the weight increase of anode by anodizing, the film thickness, and the weight increase of film by steam treatment show the Al content in the baths affect the composition of anodized film.
(4) The Al content in the baths affect on the abrasion resistance of anodized film strictly.
