Stainless steel surface treatment process with precise control of roughness

Abstract

The invention relates to a surface treatment process of stainless steel for accurately controlling the roughness. The surface treatment process comprises the following steps of firstly, preferably adopting blasting sands with greater particles to perform sand blasting on the stainless steel surface; secondly, forming a surface with greater roughness; thirdly, scraping and coating molten resin, blocking a valley structure and exposing a peak structure at the top end, thereby cutting down a part of peak structure when sand blasting for the second time is performed, in turn, operating until a satisfied result is realized. In the process, a large part of peak structure is polished, and the valley structure formed by sand blasting for the first time is basically retained, so that the height of the peak structure on the surface of a stainless steel substrate is reduced, but the width of the valley structure on the surface of the stainless steel is basically kept unchanged, and a stable sand blasting style of the surface of the stainless steel substrate can be formed; the peak structure is not easily rubbed down, a wear-resisting microstructure of the surface of the stainless steel substrate is formed, and the skidproof capability for scratches formed by scratching is remarkably enhanced. Particularly, the stainless steel substrate is higher in practicality when being applied on products such as mobile phones, notebook computers and the like.

Description

technical field [0001] The invention relates to a stainless steel treatment method, in particular to a stainless steel surface treatment process for precisely controlling 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 deficiencies 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: ...
