摘　　要：连杆小头衬套和活塞销紧密配合并随着发动机气缸活塞做往复运动,长时间往复运动易导致衬套内壁材料因发生摩擦磨损而失效,从而影响发动机运行的安全性能。本文介绍了汽车连杆小头衬套的结构及功能,并利用摩擦磨损试验仪、场发射扫描电子显微镜(FESEM)、能谱仪(EDS)等设备对CuSn_(8)Ni和CuSn_(6)P两种连杆衬套内壁材料的磨痕形貌、磨损机制、磨损量、摩擦系数等性能参数进行了研究和对比分析。The small end bushing of the connecting rod and the piston pin are closelymatch and reciprocate with the piston.The longterm reciprocating movement can easily cause friction and wear of the inner wall material of the bushing and fail,which affects the safety of the engine.In this article,the structure and function of the automobile connecting rod small head bushing are introduced.And using friction and wear tester,Field Emission Scanning Electron Microscope(FESEM),Energy Dispersive Spectrometer(EDS)and other equipment to study and compare thewear morphology,wear mechanism,and wear resistance of the two connecting rod bushing materials,CuSn8Ni and CuSn6P.
