Problems solved by technology

[0002] At present, stainless steel products gradually occupy an increasing proportion in daily life, and some traditional single stainless steel surface treatment methods can no longer fully meet people's increasing aesthetic requirements
Currently widely used stainless steel surface treatment such as pickling and passivation reduces the metallic luster of its surface. After shot blasting, the surface is rough and not resistant to dirt, and it is not easy to clean after a long time.

Embodiment Construction

[0008] Below in conjunction with the examples, the specific implementation of the present invention will be further described in detail. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention. The method includes steps: 1) mechanical polishing treatment, which can effectively remove various defects on the surface of the stainless steel workpiece and make the surface of the stainless steel smooth and even. 2) Bead spraying treatment, the surface of the stainless steel after shot blasting is sprayed with glass beads at high speed to change the appearance of the outer surface of the workpiece. Due to the impact and cutting effect of the glass beads on the surface of the workpiece, the surface of the workpiece can obtain a higher degree of cleanliness And higher roughness, the mechanical properties of the workpiece surface are improved, thus improving the fatigue resistance of the workpiece. Sandblasti...

Abstract

The invention relates to a treatment process of stainless steel and provides a process for overcoming the defects in an existing widely-applied process for stainless steel surface, such as an acid cleaning and passivation process, metallic luster of the stainless steel surface is reduced, the stainless steel surface subjected to shot blasting is rough and is not resistant to dirty, and the stainless steel surface is not easy to clean after long time. According to the treatment process disclosed by the invention, the stainless steel surface is subjected to mechanical polishing and sand blasting treatment, so that the defects of a substrate are eliminated, and the appearance of the stainless steel surface is enabled to be uniform and consistent; on the basis, the treatment effect of the stainless steel surface can be blacker and brighter, uniform and attractive by adopting electrolytic polishing treatment, so that the defects that a stainless steel part is rough and has no metal luster can be overcome; and after treatment, the stainless steel surface is glossy black and is strong in metallic texture.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to a stainless steel surface treatment process. Background technique [0002] At present, stainless steel products gradually occupy an increasing proportion in daily life, and some traditional single stainless steel surface treatment methods can no longer fully meet people's increasing aesthetic requirements. At present, the widely used stainless steel surface treatment such as pickling and passivation reduces the metallic luster of its surface. After shot blasting, the surface is rough and not resistant to dirt, and it is not easy to clean after a long time. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a stainless steel surface treatment process, which can overcome some defects of the existing stainless steel treatment process and improve the appearance grade. In order to solve the above technical pr...
