摘要(Abstract)：

通过超声分散和球磨相结合的方法制备镀铜石墨烯增强Ti6Al4V(GNPs-Cu/Ti6Al4V)复合粉体,采用真空热压法制备了GNPs-Cu/Ti6Al4V复合材料。采用X射线衍射仪、扫描电镜、显微硬度计、万能试验机和摩擦磨损试验等研究了复合材料的相组成、微观结构、硬度、抗压强度和磨损性能。结果表明:当GNPs的添加量为0.8 mass%时,复合材料的力学性能最好,其显微硬度和抗压强度分别为575.2 HV0.1和2169.34 MPa,与Ti6Al4V基体相比,分别提高了21%和18.1%。GNPs-Cu/Ti6Al4V复合材料强化机制主要有GNPs强化、Ti_2Cu和TiC的第二相强化。复合材料磨损机制以磨粒磨损为主,同时伴随着粘着磨损。
