Abstract: Disclosed are an electrolytic oxidation solution for use in aluminum alloy oxidative film formation, and a method for aluminum alloy oxidative film formation. The electrolytic oxidation solution comprises the following components: 0.1-1 g/L of ammonium hydrogen difluoride, and 5-60 g/L of oxalic acid, the oxidation solution comprising Al  3+  at a balanced concentration of 0.01-1 g/L. The method for aluminum alloy oxidative film formation comprises conducting an electrolytic process using the above electrolytic oxidation solution to form a layer of organic and inorganic fluorine-containing oxidation film on a surface of an aluminum alloy by means of a synergistic action of chemical film formation and electrochemical film formation. Use of the electrolytic oxidation solution according to the present invention to conduct film formation by electrolytic oxidation can achieve a fast film formation process due to the synergistic action of chemical film formation and electrochemical film formation. An ionization equilibrium will generally occur when an aluminum ion concentration in the oxidation solution reaches about 0.1 g/L, such that the aluminum ion concentration no longer increases. Therefore, the oxidation solution can be recycled instead of being changed, and thus produces less solid waste in comparison to the prior art.
