摘　　要：为研究氮化硅全陶瓷轴承在水中的磨损特性,制备了6202全陶瓷深沟球轴承,在水介质轴承专用跑合仪上进行不同温度水介质中的跑合试验。试验后利用TP-107轮廓仪对轴承内圈沟道表面粗糙度进行分析,利用激光共聚焦显微镜、扫描电子显微镜(SEM)对轴承内圈沟道磨损形貌进行微观观察。结果表明:在水介质中跑合可降低陶瓷轴承内圈沟道的表面粗糙度值;轴承的磨损率随水介质温度的升高而增大。In order to study wear characteristics of Si3N4 full-ceramic bearings in water,the full-ceramic deep groove ball bearings 6202 are prepared.The running-in tests are carried out on special running-in instrument for the bearings in water medium under different temperatures.After tests,the surface roughness of inner ring raceway is analyzed by profilometer TP-107.The microscopic observation is carried out for wear morphology of inner ring groove by using laser confocal microscope and scanning electron microscopy.The results show that the running-in in water medium decreases surface roughness of inner ring raceway of ceramic bearings,and the wear rate of the bearings increases with increase of temperature of water medium.
