| 摘 要： | 在XP-5型高温摩擦磨损试验机上考察了MoSi2与Al2O3、SiC和Si3N4配对副在1000℃大气环境不同滑动速率下的摩擦磨损行为,利用扫描电子显微镜和X射线衍射仪分析了试样的磨损表面形貌和相组成.结果表明:随着滑动速率的增加,摩擦系数和MoSi2的磨损率均呈下降趋势,SiC为更适合于MoSi2的高温配对副材料.与Al2O3配对时,MoSi2的磨损机理主要表现为黏着和氧化;与SiC和Si3N4配对时,MoSi2的磨损机理为研磨、轻微氧化和点蚀.

| Abstract: | The friction and wear properties of molybdenum dislicide (MoSi2) against Al2O3, SiC and Si3N4 at different sliding speeds at 1000?C in air were investigated on an XP-5 type high temperaturefriction and wear tester. Morphologies and phase compositions of the worn surfaces of MoSi2 and its counter-face materials were observed by scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD). Results showed that friction coefficient and wear rate of MoSi2 decreased with the increase of sliding speed and SiC was a suitable counter-face material of MoSi2 at high temperature. Adhesion and oxidation were the main wear mechanisms of MoSi2 sliding against Al2O3,. However against SiC and Si3N4, abrasion, mild oxidation and pitting became the main wear mechanisms of MoSi2. |
