The preparative technique of solid lubricant is cold-press sintering method.The micro-structure , friction surface, lubricant transfer film surface of base material was characterized by SEM; XRD was used to do phase analysis. The degrees of crystallinity of pure PTFE under the different conditions of water cooling, air cooling and furnace-varying cooling were made comparison by XRD. The thermal stability of pure PTFE and solid lubricant was analyzed by DSC-TG; The composition and valence state of elements in the surface of carbon fiber ,solid lubricant before and after friction test and lubricant transfer film were characterized by XPS; The frictional property of solid lubricant was tested by pin and disk test rig .
