液相烧结碳化硅陶瓷的摩擦磨损行为
Friction and Wear Behaviors of Liquid-phase Sintered Silicon Carbide Ceramics
摘要
Abstract
Friction and wear behaviors of liquid-phase sintered SiC ceramics (LPS-SiC) under conditions of dry friction and oil lubrication friction were studied by employing ring-block type friction pair with fully-dense sintered SiC ceramics (S-SiC) as the friction ring.The results show that under the dry friction condition,the friction and wear of LPSSiC contained three stages of running-in wear,stable wear and severe wear,and the wear mechanism was a mixture mode of abrasive wear and brittle deprivation with a large wear volume.On the contrary,under the oil lubrication condition,the friction and wear of LPS-SiC included two stages of running-in wear and stable wear,and the wear mechanism was a mixture mode of brittle deprivation and fatigue wear with a small wear volume.The wear volume of LPS-SiC increased with the increase of applied loading and decreased with the increase of oil dropping rate.关键词
