| Abstract: | Effect of matrix hardness, chemical composition, composition segregation and nitriding process on surface hardness and depth of nitrided case of 42CrMo steel was investigated. The results show that a suitable nitriding temperature of 42CrMo steel parts is 530 ℃, and both the increase in matrix hardness and the control of alloying elements exerting an influence on the nitriding quality are advantageous to the increase in surface hardness and the production of desirable white and diffusive layers. |
