摘要
在42CrMo钢常规处理的基础上增加了冷处理,研究浅冷处理和深冷处理对42CrMo钢硬度和耐磨性的影响。结果表明,经浅冷处理和深冷处理后,42CrMo钢中残留奥氏体向马氏体发生转变,且碳化物析出增多,致使钢的硬度和耐磨性均有提升,且深冷处理后硬度和耐磨性提升幅度高于浅冷处理。
Based on the conventional treatment of 42CrMo steel,cryogenic treatment was added.Effects of shallow cryogenic treatment and deep cryogenic treatment on hardness and wear resistance of 42CrMo steel were studied.The results show that after shallow cryogenic treatment and deep cryogenic treatment,the retained austenite in 42CrMo steel transforms to martensite,and the precipitation of carbides increases,which leads to the improvement of hardness and wear resistance of the steel,and the improvement extent of hardness and wear resistance after deep cryogenic treatment is higher than that of shallow cryogenic treatment.
