摘　　要：利用S250 Mk3扫描电镜和WJ-10B型万能材料试验机对EK3205、M170D和T163D 3种浸锑石墨材料组织结构、机械性能和摩擦磨损性能进行了对比试验。试验结果表明:3种材料成分和组织结构基本相同,机械性能和磨损性基本相当;T163D和M170D摩擦因数(0.130和0.135)要比EK3205的(0.140)低;基体材料越致密,孔隙分布越均匀,添加超细粉因体有利于润滑膜的形成与稳定,有利于减小摩擦因数。The materials of EK3205,M170D and T163D were chosen as research objects.Using scanning electron microscope（SEM） and WJ-10B universal testing machine to finish the contrast test of material’s organization structure,mechanical character and friction and wear properties.The results show that 3 kinds of materials have similar component and organization structure,accordant mechanical character and friction and wear properties.Friction factors ofT163D and M170D（0.130 and 0.135） are lower than that of EK3205（0.140）.The denser substrate material,themore uniform the pore distributies,and adding superfine powder is helpful for the form and stability of lubricant film,and the reduction of friction coefficient.
