摘　　要：采用SRV试验机,利用分段试验的方法对渗陶瓷活塞环与铜铬镍钼气缸套组成的摩擦副配对,在含石英砂磨粒的润滑条件下的磨粒磨损过程进行了研究。结果表明,当磨粒硬度远高于摩擦副表面硬度时,摩擦副表面的硬度对其抗磨粒磨损性能起决定性作用,材料硬度越大,其抗磨粒磨损性能越好。The abrasive wear process of the frictional pairs constituted by ceramic piston ring/Cu-Cr-Ni-Mo cylinder bores lubricated by the lubricating oil with certain amount of quartz sand was studied by SRV subsection experimentation.Results show that the surface rigidity of frictional pairs play crucial effect in capability of resisting abrasive wear when the rigidity of quartz sand is higher than that of the surface of frictional pairs,the stronger the rigidity of the material is,the better the capability of res...
