| 摘 要： | 以硼砂基盐和供钒剂为主要原料,利用热辐射效应在Cr12MoV钢表面制备了VC涂层,通过扫描电子显微镜、能谱分析仪观察了涂层显微组织,考察了涂层在室温往复干摩擦条件下的耐磨性能,测试了VC涂层摩擦系数,对其磨损机制进行了分析.结果表明：VC涂层主要由团聚状VC颗粒组成,其组织结构均匀,与基体之间形成完全冶金结合;涂层在滑动干摩擦条件下表现出优异的耐磨性能,VC涂层磨损机制主要为疲劳磨损和磨粒磨损.

| Abstract: | By using borax salt and vanadium as the main materials, the VC (Vanadium Carbide) coating was prepared on the surface of Cr12MoV steel with a TD (thermal diffusion) process. The micro-structures of the coating were observed with SEM and EDS. The reciprocating friction and wear of Cr12MoV steel disk against a steel ball under unlubricated condition at room temperature were evaluated and wear mechanism were analyzed. The results show that VC coating was composed of flocculent aggregate VC grains and had a uniform structure. The metallurgical bonding was found at the coating/substrate interface. VC coating showed excellent resistance to wear under the unlubricated condition. The wear mechanism of VC coating was a combination of fatigue wear and abrasive wear. |
