The utility model discloses an aluminum alloy with an army green micro-arc oxidation ceramic membrane on the surface, and is used for solving the technical problem that the ceramic membrane treated by a light metal micro-arc oxidation technology mostly is ash grey, white, black and the like in the prior art. The solute of the electrolyte disclosed by the utility model adopts sodium phosphate, sodium silicate, sodium hexametaphosphate, sodium hydroxide, ethylene diamine tetraacetic acid, potassium dichromate, sodium carbonate, lauryl sodium sulfate and hydrogen peroxide, and the solvent adopts deionized water to prepare alkaline electrolytic solution; the alkaline electrolytic solution is agitated and placed for 1-2 hours; and then the aluminum alloy with the army green micro-arc oxidation ceramic membrane on the surface is obtained by micro-arc oxidation treatment. The aluminum alloy with the army green micro-arc oxidation ceramic membrane on the surface disclosed by the utility model has the beneficial effec
