采用超音速等离子喷涂技术制备了添加稀土氧化物的Cr 3C 2-NiCr涂层。采用X射线衍射仪、接触表面形貌仪、硬度计、微摩擦磨损试验机、环境扫描电子显微镜和能谱仪分别对镀层的相结构、表面形貌、显微硬度和摩擦性能进行了研究。结果表明，添加稀土氧化物的Cr 3C 2-NiCr涂层的表面粗糙度、显微硬度、脆性断裂、摩擦系数和耐磨性均较未添加稀土氧化物的涂层有明显改善。并对摩擦及摩擦机理进行了讨论。(c)2006 Elsevier B. V.保留所有权利。
A novel supersonic plasma spraying was used to prepare rare earth oxide added Cr3C2-NiCr coatings. X-ray diffractometer, contact surface profiler, hardness tester, micro-friction and -wear tester, environmental scanning electron microscope equipped with energy dispersive spectroscopy were employed to investigate the phase structure, surface morphology, microhardness, and friction properties of deposited coatings, respectively. The results show that surface roughness, microhardness, brittle fracture, friction extent and wear resistance of rare earth oxide added Cr3C2-NiCr coatings are effectively improved compared with that of unadded one. The friction and friction mechanism are also discussed. (c) 2006 Elsevier B.V. All rights reserved.
