摘要

摘要: 采用标准摩擦试验机研究了3种石墨(兰州石墨、上海三高石墨和IG-11)的摩擦性能,并用电子扫描显微镜分析了摩擦表面。试验的环境气氛为氦气和空气。研究结果表明:在相同载荷作用下,3种石墨在不同环境气氛中表现出不同的摩擦性能。当滑动速度较大时,在空气环境中的摩擦系数高低依次为兰州石墨>上海三高石墨>IG-11;在氦气环境中的摩擦系数则为上海三高石墨>IG-11>兰州石墨。

Abstract: The tribological behaviors of three grades of graphite, Lanzhou graphite,Shanghai Sangao graphite and IG--11, are investigated by the normal friction testerSRV. And the friction surfaces are analyzed by a scanning electron microscope. The ex-perimental environments are selected as helium and air. The results show that the fric-tion behaviors are different in different gas environments with the same load for allgraphite. At the large sliding velocities, the order of friction coefficient is Lanzhougraphite>Shanghai Sangao graphite>IG--11 in air, and in helium the order is ShanghaiSangao graphite>IG--11> Lanzhou graphite.
