【摘要】 工程陶瓷的磨损量,除与陶瓷本身的摩擦学性能、润滑及承载条件有关外,与配对材料的性能也有密切的关系．为研究配对材料硬度对陶瓷磨损量的影响,使用Al2O3,ZrO2和Si3N4工程陶瓷与不同硬度的灰铸铁、球墨铸铁配对,在乳化液润滑下进行了滑动磨损试验．研究结果表明,尽管配置副铸铁的硬度远小于陶瓷,陶瓷的磨损量亦随配副铸铁硬度的增大而提高．更多还原

【Abstract】 Wear of ceramics is closely related to properties of coupled material besides lubncation,load and ceramics themselves. In order to investigate the effects of hardness of coupled material on wear of ceramics. Al2O3, ZrO2 and Si3N4 are used for doing sliding wear against different hardness cast irons lubricated by emulsion.The results showed that wear of ceramics increases with the hardness of coupled cast irons although the hardness of ceramics is much higher than that of cast irons.更多还原
