Problems solved by technology

[0002] At present, the appearance parts of mobile terminals are basically colored by surface treatment technologies such as anodic oxidation, spray coating, electrophoretic deposition, and vacuum coating, so as to achieve decorative functions. However, the current surface coloring technologies either consume high energy consumption or cause serious environmental pollution. In addition, surface treatment technologies such as anodic oxidation, spray coating, electrophoretic deposition, and vacuum coating are all surface coating technologies. The pretreatment process is cumbersome, the bonding force between the film and the substrate is weak, the wear resistance is relatively poor, and the texture is very bad.

Abstract

The present invention proposes a method for preparing an alloy ceramic film, a mobile terminal casing and a mobile terminal, wherein the method for preparing the alloy ceramic film includes: when the laser beam is performing laser laser process on the surface of the alloy plate , blowing a designated reaction gas onto the surface of the alloy plate to form an alloy ceramic film on the surface of the alloy plate. Through this technical scheme, the surface of the alloy plate is directly treated with laser and the specified reaction gas is blown, so that the alloy ceramic film formed on the surface of the alloy plate has good hand feeling, high hardness, good wear resistance, and Corrosion, and can achieve a good decorative effect, and the preparation method of the alloy ceramic thin film is simple, does not require the coating technology on the alloy plate, reduces the process flow, thereby effectively protecting the environment.

Description

technical field [0001] The invention relates to the technical field of terminals, in particular to a method for preparing an alloy ceramic film, a mobile terminal shell and a mobile terminal. Background technique [0002] At present, the appearance parts of mobile terminals are basically colored by surface treatment technologies such as anodic oxidation, spray coating, electrophoretic deposition, and vacuum coating, so as to achieve decorative functions. However, the current surface coloring technologies either consume high energy consumption or cause serious environmental pollution. In addition, surface treatment technologies such as anodizing, spraying, electrophoretic deposition, and vacuum coating are all surface coating technologies. The pretreatment process is cumbersome, the bonding force between the film and the substrate is weak, the wear resistance is relatively poor, and the texture is very bad. [0003] Therefore, how to propose a preparation method of an alloy c...
