Stainless steel surface treatment process with precise roughness control

Abstract

The invention relates to a stainless steel surface treatment process with a precise roughness control function. The stainless steel surface treatment process comprises the steps that large-particle blasting sand is preferably adopted for carrying out sand blasting on a stainless steel surface, and a surface with a large roughness degree is formed; then, blade coating of fusion resin is carried out, a valley structure is blocked, and a peak structure at the top end is exposed; and then secondary sand blasting is carried out, and part of the peak structure is cut down till a satisfying effect is achieved. In the process, most part of the peak structure is ground off, the valley structure formed during primary sand blasting is basically kept, the height of the peak structure on the surface of a stainless steel base material is reduced, but the width of the valley structure on the surface of the stainless steel base material is basically kept unchanged, and therefore a steady sand blasting style on the surface of the stainless steel base material can be formed. The peak structure is not prone to be ground flush, a grinding-resisting microstructure on the surface of the stainless steel base material is formed, and the sliding resisting capacity to scratches caused by scratching is remarkably enhanced. Especially when used for mobile phones, notebook computers and other products as a shell, the stainless steel base material is more practical.

Description

technical field [0001] The invention relates to a stainless steel treatment method, in particular to a stainless steel surface treatment process with precisely controlled roughness. Background technique [0002] Generally, a surface with a larger roughness can be sprayed out by sandblasting with a smaller mesh number, and vice versa, a surface with a smaller roughness can be sprayed out. The surface microstructure with a certain roughness can be divided into protruding peak structure and concave valley structure, but it cannot be realized in the existing technology. The peak structure is polished to form a more stable and more wear-resistant sandblasting surface after sandblasting. Contents of the invention [0003] The invention overcomes the shortcomings of the prior art and provides a stainless steel surface treatment process with precisely controlled roughness. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: ...
