用扫描电镜中的摩擦磨损原位观察装置研究Al2O3-TiC-Co复合材料在单磨粒作用下的摩擦磨损性能．该陶瓷的摩擦特性随磨损环境不同而表现出不同的性能磨损率随磨损载荷的增加呈抛特线型上升证实其微观磨损机理以微切削和脆性断裂为主
The friction and wear properties of Al2O3-TiC-Co composites under the effect of single abrasive grains were investigated by means of in situ scanning electron microscopy (SEM). The tribological properties of the ceramics show different properties with different wear environments. The wear rate increases with the wear load and increases linearly with the increase of abrasion. It testifies that the microscopic wear mechanism is dominated by micro-cutting and brittle fracture
