Abstract

The invention relates to the field of surface treatment of aluminum alloys, in particular to a treatment method of aluminum alloy surface textures and a prepared aluminum alloy product. The treatment method comprises the following steps: a three-dimensional texture pattern on the surface of the aluminum alloy product is designed; a three-dimensional texture pattern complementary with the three-dimensional texture pattern in shape is carved in the inner wall of a molding cavity of a mold for preparing the aluminum alloy product; the aluminum alloy product to be machined is put in the molding cavity of the mold for texture hot pressing; and photo-sensitive resist is coated on the surface of the aluminum alloy product for exposure and primary anodic oxidation, and is removed for secondary anodic oxidation. The treatment method largely simplifies realization of the aluminum alloy surface textures, and has such advantages as easy realization, short time, high yield, low cost, good consistency and colorful surface texture effects.

Description

technical field [0001] The present application relates to the field of aluminum alloy surface treatment, in particular, relates to a treatment method for aluminum alloy surface texture and aluminum alloy products thereof. Background technique [0002] The most common surface effects of aluminum alloys are wire drawing, sandblasting, and the processing methods on the surface of aluminum alloy by CNC tool cutting texture, laser laser texture, etc., to achieve texture on the surface of aluminum alloy. However, the process of CNC tool cutting and processing texture has the disadvantages of limited texture, long time consumption, low production capacity and high cost. The texture color of laser laser processing also has limitations and differences. Due to the limited color of laser laser texture, it is impossible to make any color matching according to the required design. Moreover, the laser texture is limited to two-dimensional patterns, and cannot achieve three-dimensional ef...
