摘　　要：对4Cr5MoVISi钢B-S复合渗的最佳工艺进行了探讨,对复合渗的渗层组织和结构进行金相、x射线及离子探针分析,结果表明,经B-S复合渗样品表面在获得高硬度渗硼层基础上覆盖一层较薄的渗硫层,使其耐磨性进一步提高。Combined boriding and sulfurizing treatment of 4Cr5MoVlSi steel was studied. The surface layer was analysed systematically by metallographic, X-ray and ion probe examination. It was proved that the surface is a thin sulfurizing layer based on a high hardness boriding layer and the wearability increases remarkably.
