| 摘 要： | 本文研究了高温结构陶瓷Ｓｉａｌｏｎ、Ａｌ２Ｏ３、ＳｉＣ的自配对滑动干摩擦磨损性能，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$ 微剥离磨损，摩擦过程中产生的氧化产物能改善材料摩擦；Ａｌ２Ｏ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

| Abstract: | Friction and wear behaviors were studied for Sialon, Al2O3 and SiC unlubricated sliding against themselves with block-ring apparatus at 5ON normal load and 0.9m/s sliding velocity. All materich and worn surfaces as well as debris were extensively characterized by means of SEM, TEM and XPS. The results obtained indicated that: Wear of Sialon is interpreted in terms of delamination. In the processing, the oxidation and its formation appeared. Mixed surface film of SiO2 and Al2O3 improved the wear of Sialon. Wear of Al2O3 is explained in terms of the grain fracture. Wear of SiC is caused by the formation of powders and loose wear debris which was due to the oxidation of SiC. |
