Abstract

Abstract: the friction and wear properties of polytetrafluorethylene(PTFE) composites filled with nano-titanium nitride (TiN) were evaluated with an MM-200 friction and wear tester. the worn surfaces of the composites were examined by means of scanning electron microscopy (SEM).It has been found that the incorporation of nano-TiN into PUFF increased the hardness and wear resistance of PTFE. the best wear-resistance of the composite was reached at a mass fraction of nano-TiN about 7%，and the wear amount of composites increased with increasing load. the addition of the nano-TiN also decreased the friction coefficient of PTFE.

Key words: nano-titanium nitride, polytetrafluorethylene, composite, friction, wear
