Tribological Behavior of Vacuum Plasma Sprayed B4C-Mo Composite Coating

Keywords： B4C-Mo composite coating , tribological behavior , vacuum plasma spray

采用真空等离子体喷涂技术制备了B4C-Mo复合涂层,并对其耐磨性能进行了研究.与B4C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B4C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.
