Jiaxing bearing, bearing steel surface deformation strengthening

Jiaxing bearing group sales co. , LTD. , is the spot sales center of jiaxing bearing factory, specializing in HRB bearings, application in production design and related machinery has a wealth of technical experience, today we are together and we learn the bearing steel surface deformation strengthening. Bearing steel surface deformation strengthening: by mechanical method of plastic deformation in the metal surface, so as to form a hardening layer with high hardness and high strength, this kind of surface strengthening method called surface deformation strengthening, also known as work hardening. Including shot peening, sandblasting, cold extrusion, rolling, cold grinding and impact and explosion shock processing, etc. The characteristics of these methods are: strengthening layer increased dislocation density, the crystal structure refinement, so that the hardness and strength increased, the surface roughness value decreases, and can significantly improve the surface fatigue strength of parts and reduce fatigue notch sensitivity. This improved method craft simple, the effect significantly, there is no obvious boundaries between hardening layer and matrix, the coherent structure and not easy to fall off in use. Its most method has been applied in the bearing industry: roller surface strengthening is the application of this kind of method, precision rolling has become a new ring processing and strengthening method.
