| 摘 要： | 在MM200摩擦磨损试验机上对高速电弧喷涂3Cr13涂层在干摩擦条件下的加速磨损机理进行了研究.涂层在加速磨损过程中经历了跑合磨损、稳定磨损、剧烈磨损这三个不同的阶段.采用扫描电镜、X射线衍射仪、显微硬度仪和纳米压痕仪对涂层磨损各阶段的截面形貌、残余应力、硬度和纳米力学性能进行了表征.结果表明:在加速磨损寿命3个阶段中,涂层的磨损机制和影响残余应力的主导因素是动态变化的,过分的冷作硬化加剧了涂层的失效,涂层磨损寿命长短关键在于稳定磨损时间的长短.

| Abstract: | The MM200 tribo-tester was used to investigate the accelerated wear life mechanism of 3Cr13 coating prepared by high velocity arc spraying under dry friction condition.The cross-sectional microstructure,hardness and residual stress of the coatings were analyzed and observed by means of SEM,XRD,Vicker hardness tester and Nano-test 600 indentation tester under an accelerated wear process of coatings,which consists of run-in wear,stable wear and severe wear.The results of experiments showed that the wear mecha... |
