Preparation method for golden aluminum alloy conductive oxidation film

The invention relates to the technical field of aluminum alloy conductive oxidation films, in particular to a preparation method for a golden aluminum alloy conductive oxidation film. The preparation method comprises the steps that impurities are removed through gasoline; soaking is conducted through a sodium hydroxide solution for degreasing; washing is conducted, and soaking is conducted through a nitric acid solution for bright dipping; washing is conducted, and then anodic oxidation is conducted; and washing, dyeing, washing, drying, packaging and the like are conducted, and the compact protecting film is formed on the surface of an aluminum alloy material. Oxidation film holes are formed in the film, so that the color of the surface of the dyed aluminum alloy material is uniform, and the dyeing consistency of the aluminum alloy material is improved; in addition, the thickness of the oxidation film is 0.005-0.008 micrometer, the corrosion resistance of the aluminum alloy material is effectively improved, and it is guaranteed to the greatest extent that the conductivity of the aluminum alloy material is good, so that the surface contact resistance of the aluminum alloy material is 21.7-22.1 m omega.
