摘　　要：采用固体渗碳技术对23CrNi3Mo钢进行表面渗碳处理,观察表面渗碳层的微观组织,建立碳含量、浓度与渗碳时间、温度之间的数学关系。结果表明,表面碳浓度为0.72%～0.81%时能够获得良好渗碳效果。The microstructure of the surface carburization 23CrNi3Mo steel was analyzed, and the mathematical relationship between carbon content, carbon concentration and carburizing processes were studied. The results show that the carburization result is good when the carbon concentration is 0.72%-0.81%.
