| Abstract: | The friction coefficient and wear coefficient of hot-pressed Si3N4sliding unlubricated against 3Cr2W8V steel are measured by using a pin-on-discfriction tester at the room temperature. The worn surface of ceramics is bbservedand analyzed by the scanning electron microscope, X-ray diffractometer and electron probe microanalyzer. The wear mechanism of the ceramics is studied. Theresult shows that the wear of St,N. ceramics is mainly attributed to the brittle microfracture mechanism. |
