摘　　要：采用SRV试验机分段试验方法,对喷钼活塞环与磷硼气缸套组成的摩擦副,在石英砂磨粒条件下的抗磨粒磨损机制进行了研究。结果表明,摩擦副材料的表层结构和化学组成对磨粒磨损性能有显著影响;喷Mo活塞环/气缸套摩擦副受磨粒磨损的影响不大,喷钼活塞环具有良好抗磨粒磨损性能。The mechanism of the tribomate pairs＇ anti-abrasive wear（ Mo-alloy sprayed piston ring/P-B cylinder bore ） under certain amounts of quartz sand was studied by SRV subsection experimentation. Results show that the surface structure and chemical component of tribomate materials place a remarkable influence on the capability of anti-abrasive wear, and abrasive particle has little influence on the wear of Mo-alloy sprayed piston ring/P-B cylinder bore. Mo-alloy sprayed piston rings possess excellent performance of anti-abrasive wear.
