The Nano-Al2O3 and PEEK particles synergetic filled PTFE composites were prepared by mechanical blending-molding-sintering method. The tribological behavior of composites with different volume fraction of fillers was tested on different test conditions by a MMW-1A block-on-ring friction and wear tester. The transfer film on counterpart 5A06 Alumin m alloy ring was inspected and anslyzed with scanning electronic microscopy (SEM) and X-ray diffraction(XRD).The results demonstrated that the lowest friction coefficient was gained when the PTFE composite was filled with only 10% PEEK. The friction coefficient decreases gradually with the increasing content of PEEK. The special wear rate of 10% PEEK/PTFE were decreased clearly with filled different contents of nano-Al2O3 particles. The special wear rate of the sample with 5% nano-Al2O3 and 10% PEEK had the lowest volume wear rate. The sliding speed effect significantly on the tribological behavior of nano-Al2O3/PEEK/PTFE composites.
