摘　　要：采用真空等离子体喷涂技术制备了B_4C-Mo复合涂层,并对其耐磨性能进行了研究。与B_4C纯涂层相比,复合涂层结构更为致密,(B,Mo)C过渡相的存在改善了B_4C相与Mo相之间的润湿性,进而有效提高了涂层的抗摩擦磨损性能。此外,Mo在喷涂过程中形成了大量的纳米晶,这也在一定程度上促进了复合涂层耐磨性能的提高。A B4C-Mo composite coating was fabricated using a vacuum plasma spray technique, and its wear behavior was compared with that of a pure B4C coating. The microstructure of the composite coating was much more homoge- neous and compact as a result of the formation of a （13, Mo） C transition phase, which effectively improved the inter- face between BaC and Mo splats. For this reason, the wear resistance of the composite coating was much superior to that of the pure BaC coating. The distribution of nano-sized Mo in the composite coating might also contribute to the improved tribological properties.
