摘要：

Blending the principle of pre-stressed grinding and grinding hardening, an pre-stressed hardening grinding approach was presented. The microstructure, distribution characteristics, thickness and hardness of the grinding hardening layer were studied. The results showed that under the same condition, the microstructure and distribution characteristics of grinding hardening layer in pre-stressed hardening grinding was the same as in grinding hardening and the microstructure was the subcritical quenching. Pre-stressed hardening grinding process showed more restraint effect on grinding heat. The hardening layer thickness and hardness of pre-stressed hardening grinding specimens were slightly below the grinding hardening specimens, but the surface hardness was able to reach the general complete quenching state. The research provides the experiments and principle basis for pre-stressed hardening grinding process development and work-piece surface quality control. ©, 2015, Northeastern University.
