本文研究了高温结构陶瓷Sialon、Al2O3、SiC的自配对滑动干摩擦摩损性能，运用SEM、TEM、XPS手段观察和分析了磨损面的表面形貌、磨屑形状及相组成.目的是揭示陶瓷材料在试验条件下的滑动干摩擦磨损规律和摩擦磨损机理.结果表明：Sialon是微剥离磨损，摩擦过程中产生的氧化产物能改善材料摩擦;Al2O3的磨损机理是磨屑边界润滑下的晶粒拔出和沿晶断裂;SiC表现为犁沟-磨屑-犁沟过程的磨损，并伴有摩擦氧化发生.
In this paper, the self-matching sliding dry friction and wear properties of high temperature structural ceramic Sialon, Al2O3 and SiC were investigated. The surface morphology, wear debris shape and phase composition of wear surface were observed and analyzed by SEM, TEM and XPS. The results show that Sialon is a micro-peel-off wear, and the oxidation products generated during the friction process can improve the friction of the material. The wear mechanism of Al2O3 is that the grain under the lubrication of the wear debris boundary Pull out and intergranular fracture; SiC showed the furrow - debris - furrow wear process, accompanied by frictional oxidation occurred.
