摘　　要：利用离子渗钼-渗硫复合处理的方法在Ti-6Al-4V表面形成复合涂层,用扫描电镜和EMAX能谱仪分析复合涂层表面微观形貌和组织成分,用X射线衍射仪分析了复合涂层的相结构,用显微硬度计分析基体以及各渗层表面的显微硬度。结果表明:复合涂层由细小且大小均匀的球状颗粒随机堆积镶嵌而成,表面平整、均匀;复合涂层主要由Mo和MoS2组成,该复合涂层是理想的摩擦学表层结构。发现Mo的硫化处理不同于钢铁材料的低温渗硫,在较高温(650℃)下渗硫较为合适。A composite layer was made on Ti-6Al-4V surface with the way of ionodialysis molybdenum and ionodialysis sulfur. The surface microstructure of composite coating was detected by SEM and the surface components was tested by energy dispersion spectrum. The surface composite coating phase structure was analyzed by X-ray diffraction. The surface microhardness of matrix and composite coating was measured by microhardness tester. The results show that the composite coating is set up random by small size particles and the surface of the formed composite layer is uniform and fiat. The composition of composite coating mainly are Mo and MoS2. And the composite coating is the ideal tribological surface structure. The ion sulphurizing in Mo and steel materials is different and the high temperature （650℃） of ion sulphurizing in the surface of Mo is more appropriate.
