摘要:
以添加了少量氧化镧的团聚纳米Al2O3-13%TiO2粉末为原料，利用等离子喷涂技术制备了纳米陶瓷涂层。在MMS-1G型高速摩擦磨损试验机进行了摩擦磨损试验，利用扫描电镜和能谱仪对磨损表面进行了表征。结果表明：涂层组织呈现出典型的层状结构特征，界面结合良好。在高速摩擦磨损试验中，随着载荷的增加，涂层摩擦因数下降,而涂层微裂纹扩展引起涂层剥落，导致磨损率升高。

Abstract:
The nano-ceramic coating was prepared by plasma spraying with nano Al2O3-13%TiO2 powders as raw material added a small amount of La2O3. The friction properties were tested on the MMS-1G highspeed friction and wear tester, and the morphology was observed after wear by scanning electron microscopy. The results showed that the coatings exhibit typical layered structure and have a good bonding interface. In the high-speed friction and wear test, the coating friction coefficient is decreases with the increase of the load, and the expansion of micro-crack causes the coating to peel off, leading the wear rate to increase.
Key words:  plasma spraying  nano coating  friction coefficient  wear rate
