Strengthening and heat treatment on the surface of a bearing parts

The working surface and the core of the bearing parts are quite different in terms of condition, structure and performance requirements, and the overall heat treatment often makes the two tasks unable to be balanced, and the potential of the material cannot be fully utilized. The application of material surface strengthening technology can not only better solve the difference in the structure and requirements of the surface and the core, but also further enable the surface to obtain some special working performance to meet the performance of the bearing working under specific conditions. Requirements. This is of great significance in the development of modern science and technology. Traditional surface strengthening methods belong to the category of heat treatment in technology. However, surface strengthening methods such as laser, electron beam, and ion beam developed in modern times not only apply some high and new technologies to the surface strengthening of materials, but also have gone beyond the scope of traditional heat treatment in process, forming new technical fields. Therefore, the current surface strengthening technology can form a variety of classification methods from different angles. According to the physical and chemical process of surface strengthening technology, it can be roughly divided into five categories: surface deformation strengthening, surface heat treatment strengthening, chemical heat treatment strengthening, and surface metallurgy strengthening , Surface film strengthening.
