Abstract

The embodiment of the invention belongs to the field of material treatment and relates to a treatment method for aluminum alloy materials. The treatment method comprises the following steps that the surfaces of the aluminum alloy materials are subjected to pretreatment; the surfaces of aluminum alloy materials after pretreatment are subjected to two or more times of abrasive blasting treatment, and thus two or more layers of abrasive blasting layers are formed, wherein the abrasive blasting layer formed through first-time abrasive blasting is a background layer, and other the abrasive blasting layers are pattern texture layers; and aluminum alloy materials which are subjected to two or more times of abrasive blasting treatment are subjected to anode oxidation dyeing treatment. By adoption of the treatment method for the aluminum alloy materials, multi-layer pattern textures can be formed, the pattern textures have layering and stereoscopic impression, and thus the appearance effects of the outer surfaces of the aluminum alloy materials are more abundant; and meanwhile, metal texture of the aluminum alloy materials can be reserved.

Description

technical field [0001] Embodiments of the present invention relate to the field of material processing, and in particular to a method for processing aluminum alloy materials. Background technique [0002] At present, the use of aluminum alloy materials for consumer electronics products has become the mainstream, such as mobile phone casings. The surface treatment technologies commonly used in the surface treatment process of general aluminum alloy materials are: [0003] 1) Anodic oxidation process after spraying a single sand effect; [0004] 2) Anodizing process after wire drawing; [0005] 3) Spraying process. [0006] In the process of realizing the present invention, the inventor found that the current technology has at least the following problems: the surface texture of the aluminum alloy material treated by the single sand effect post-anodization process and the wire-drawing post-anodization process is single, and there is only a frosted feeling without any Patter...
