| 摘 要： | 在精密卧式磨床M7132A上对42CrMo钢进行磨削淬火试验,研究磨削淬火强化层的组织形貌、显微硬度、强化层厚度及耐磨性。结果表明:42CrMo钢进行磨削淬火,强化层主要是由板条状马氏体组成,显微硬度达到771.8HV,与基体相比提高3倍以上;强化层厚度是以最小值t1为有效使用值;与调质态基体相比,磨削淬火强化层的耐磨性提高2~9倍。

| Abstract: | Grinding and quenching experiment of the 42 CrMo steel was done on the-precision grinding machine M7132,and the microstructure,micro-hardness,strenghened layer's thickness and wear resistance were studied.The results show that grinding and quenching strengthened layer of 42 CrMo steel is composed of lath martensite;micro-hardness reaches 771.8 HV,which is four times up on substrate.The least value t1 is effectively used on thickness of strenghened layer;Compared with substrate after-hardening and tempering,... |
