The invention provides a surface treatment method for an aluminum alloy, an aluminum alloy part and an electronic equipment shell, wherein the surface treatment method for the aluminum alloy comprisesthe following steps: anodizing an aluminum alloy matrix to form an anode oxide film on at least part of the outer surface of the aluminum alloy matrix, wherein holes are formed in the anode oxide film; and forming a color changing material layer on the outer surface of the anode oxide film when the holes are in a negative pressure condition, wherein at least part of the color changing material layer fills the holes. Therefore, when the holes are in the negative pressure condition, the color changing material layer fills the holes more easily; the binding force between the color changing material layer and the anode oxide film is relatively high; the color changing material layer is unlikely to fall; the service life is relatively long; and the color changing material layer can achieve a color changing effect according to different scenes, so that the appearance expressive force is improved and the experience consumption of a consumer is improved greatly.
Description
Technical field [0001] The invention relates to the technical field of materials and electronic equipment, and in particular to an aluminum alloy surface treatment method, an aluminum alloy piece and an electronic equipment housing. Background technique [0002] At present, aluminum alloy anodized surfaces are widely used in electronic equipment housings and other fields due to their excellent corrosion resistance, strength and wear resistance. However, the current aluminum alloy anodized surfaces have serious homogeneity and single color. The aesthetics is low, and the consumer experience is poor. [0003] Therefore, the current aluminum alloy surface treatment method still needs to be improved. Summary of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, an object of the present invention is to provide a simple, convenient, and easy-to-implement aluminum alloy surface treatme...
