摘　　要：对 2 0钢预渗碳后固体法渗铬和铬硅共渗渗层的组织和耐磨性进行了试验研究 ;结果表明 ,2 0钢预渗碳后在 940℃下进行铬硅共渗时可以获得均匀致密的渗铬层 ;与普通渗铬层相比较 ,其耐磨性提高 1倍。In this paper the microstructure and wear resistance of the chromosiliconizing layer on 20 steel with pre-carbonizing were studied.The results show that 20 st eel with pre-carbonizing could get more uniform and compact chromizing layer us ing chromosiliconizing at 940 ℃.Compared with the chromizing layer,the wear re sistance of chromosiliconizing layer was increased 1 time.
