摘要
本文通过对20CrMnMo和20CrNiMo齿轮和齿轴渗碳后采用新型淬火介质淬火,获得了很好的回火组织和力学性能.与普通的淬火油淬火相比,采用14％～16％浓度的PAG淬火处理后齿轮和齿轴的强度、冲击韧性均有很大程度提高,金相组织更均匀,淬透性也有较大幅度提高.
The 20CrMnMo and 20CrNiMo gear and gear shaft after carburizing are quenched by a new type of quenching medium to obtain good tempering microstructure and mechanical properties. Compared with ordinary quenching oil, the strength and impact toughness of gear and gear shaft are greatly improved, and the microstructure is more uniform, and hardenability is too greatly improved by the PAG quenching of concentration 14% - 16%.
