采用超音速等离子喷涂技术在纯铜基体上制备Cr2O3-Ni-5％Al(质量分数)陶瓷涂层.利用XRD、SEM、激光共聚焦显微镜(LSCM)、显微硬度仪对涂层进行表征与分析,通过Image-pro Plus图形软件计算涂层的孔隙率,并通过摩擦磨损试验评价涂层的耐磨性能.结果表明:除了喷涂过程中出现了少量铬的氧化外,起始粉末和涂层的物相没有发生变化；陶瓷涂层表面呈双态组织,其表面粗糙度(Ra)为4.763 μm;涂层断口形貌为典型的片层状组织,在涂层的抛光截面上可见紧密的富铬带均匀分布；Cr2O3涂层的孔隙率为1.2％,显微硬度为1640HV0.3；涂层在室温下的摩擦因数约为0.4,其磨损机制为磨粒磨损.
