| Abstract: | The grind-hardening test was applied on 42CrMo steel,and the microstructure and wear resistance of the grind-hardening strengthened layer were studied.The results show that the microstructure of grind-hardening strengthened layer was mainly lath martensite and the microhardness was above 700 HV.Comparing with the substrate,the wear property of the grind-hardening strengthened layer was improved obviously. |
