Problems solved by technology

[0004] However, when using the technology in the prior art, when the anode layer is broken on the surface of the metal substrate, due to the large cutting capacity of the CNC milling cutter, it is very easy to form a large step difference on the surface of the metal substrate, resulting in the surface of the metal substrate There are obvious traces of cutting

Abstract

The invention relates to a workpiece surface treatment method and a terminal shell, and belongs to the technical field of workpiece surface treatment. According to the workpiece surface treatment method and the terminal shell, a first anode layer with a first target color on the surface of a workpiece is subjected to laser carving treatment, so that the first anode layer at a first preset area onthe surface of the workpiece is removed, the first preset area on the surface of the workpiece is exposed out so that the workpiece can be subjected to secondary anodic oxidation treatment, and a second anode layer with a second target color is formed at the first preset area on the surface of the workpiece. Moreover, the controllability of carving strength is good in the laser carving treatment process, carving precision is high, and therefore segment gaps on the surface of the workpiece can be reduced and even avoided, machined traces on the surface of the workpiece are avoided and the visual effect of the workpiece is improved.

Description

technical field [0001] The present disclosure relates to the technical field of workpiece surface treatment, in particular to a workpiece surface treatment method and a terminal housing. Background technique [0002] With the widespread use of terminals such as smart phones and tablet devices, users have higher and higher requirements for richer terminal appearances. At present, in order to satisfy users' demands for rich appearances, taking a smart phone as an example, different colors are usually matched on the body of the smart phone. [0003] In related technologies, smartphones usually use a metal body with two colors, which is specifically realized through the following process: after anodizing the metal substrate once, an anode layer with one color is formed on the surface of the metal substrate; the anode layer is removed by CNC After breaking the anode layer of the metal substrate after the primary anode, and then performing a second anode on the metal substrate, t...
