| 摘 要： | 目前对氧化铈稳定氧化锆涂层的研究较少,且对涂层摩擦学性能的研究不够深入。利用超音速等离子喷涂技术,在45钢基体上制备了氧化铈稳定氧化锆涂层。采用XRD、SEM及EDS等对粉料及涂层的显微结构和物相组成进行了分析;利用划痕仪对涂层的结合力进行了测试;在干摩擦条件下对涂层的摩擦磨损性能进行了测试。结果表明:涂层在基体表面铺展良好,与基体结合紧密,结合力为30 N。载荷为200 N时涂层的质量磨损率极低,且摩擦系数随载荷的增大而减小。

| Abstract: | The cerium oxide (CeO2) stabilized zirconia (ZrO2) coating was successfully prepared on the 45 steel matrix by supersonic plasma spraying.The microstructures and phase compositions of the powders and coatings were analyzed by XRD,SEM and EDS,respectively.The binding force of the coating was tested by the scratch tester,and the friction and wear properties of the coating were tested under dry friction conditions.Results showed that the coating spread well on the substrate surface and bonded tightly to the substrate,and the binding force was 30 N.In addition,the mass wear rate of the coating was extremely low when the load was 200 N,and the friction coefficient of coating decreased with the increase of load. |
