Abstract

The invention provides a method of improving shot blasting surface fineness of stainless steel blades, which is capable of solving the problem in the prior art that the surface fineness is reduced after shot blasting treatment is implemented on the surface of the stainless steel blade through high carbon cast steel shots and greatly reducing the production cost. The method is characterized by performing surface shot blasting strengthening treatment on the stainless steel blades through stainless steel wire cutting shots.

Description

technical field [0001] The invention relates to the technical field of shot peening strengthening of stainless steel blade surfaces, in particular to a method for improving the surface finish of stainless steel blades by shot peening. Background technique [0002] At present, most of the shot peening materials for stainless steel blades are high-carbon cast steel shots. application, but it has the disadvantage of poor anti-corrosion ability. In practical application, the surface of high-carbon cast steel shot is easy to rust in a humid environment. After impacting the blade, the rust is easy to adhere to the surface of the blade, resulting in The surface has the problem that the surface finish is reduced, so it takes a lot of manpower and material resources to clean the rust adhered to the surface of the blade, so it has a negative impact on the quality and cost of the blade after shot blasting. Contents of the invention [0003] In view of the problems referred to above,...
