英文摘要	The present work aimed at exploring the tribological properties evolution of PEEK- and nano-Al2O3-filled PTFE composites during the friction process. PTFE was referenced with different volume fraction PEEK and Al2O3 nanoparticles, then cold pressed and sintered by welding furnace according to the temperature control program. The tribological performance of composites was measured by MRH-3 tribological behavior tes-ter, which provided experimental data at different friction stages, and the instantaneous wear rate was calculated throughout the entire friction process. The morphology of the wear surface of samples and the transfer film on the counterpart ring was observed with scanning electronic microscopy (SEM). Analysis of contact stress of composites in friction process was carried out by using simulation software ABAQUS. The results showed that the PEEK and nano-Al2O3 particles significantly improve the wear resistance of PTFE. PTFE composite filled with 10%PEEK particles displays the best wear resistance performance (wear rate 3.69×10-6 mm3/(N•m)) and the lowest friction coefficient (0.19), and the addition of 5% nano-Al2O3 contributes to higher hardness and thermal diffusivity. The instantaneous wear rate appeared to increase first sharply and then decrease during the friction process, and finally maintained a steady change trend. The contact pressure of the sample was determined to decrease rapidly with the increase of the loss mass in the initial stage of friction, and gradually level off at the later stage. © 2019, Materials Review Magazine.
