Abstract Nanometer SiC(Nano-SiC)particles and polyimide (PI) synergetic filled polytetrafluoroethylene (PTFE) compo-sites were prepared by high speed mechanical mixer, cold press molding and sintering with temperature control program. The tribological behavior of composites and the worn surface temperature was tested by a MRH-3 block-on-ring friction and wear tester under different conditions. The worn surface and transfer film were inspected and analyzed with scanning electronic microscopy (SEM). The results demonstrated that the change of the worn surface temperature, the tribological behavior, the worn surface morphology and the transfer film of composites related to the content of nano-SiC, load and sliding velocity. With the increase content of nano-particles, the friction temperature rose more quickly into the steady stage, which was helpful to reduce the wear rate of the compo-site. When the load increased from 100 N to 400 N and the velocity increased from 1 m/s to 4 m/s, the tribological behavior of composites deteriorated quickly, the surface morphology and the transfer film changed significantly. The wear rate of the composites under heavy and high velocity conditions was high. The change of tribological behavior are not obvious within the ambient temperature to 135 ℃.
