Mechanics| friction and wear properties of inorganic filled Ekonol/ PTFE composites

The mechanics , f riction and wear properties of graphite/ MoS₂ filled Ekonol/ PTFE composites werestudied. The result shows that the addition of graphite/ MoS₂ not only increases the mechanical properties ofEkonol/ PTFE composites , but also causes the f riction coefficient to increase , the wear volume to decrease , and theabrasive resistance to remarkably increase. When Ekonol and graphite/ MoS₂ mass f ractions are 5 % and 8 % , thetensile st rength and bend st rength of composites increase 31 % and 41 % , and the hardness increases 713 % too. Thewear mechanism of Ekonol/ graphite/ MoS₂ / PTFE composites is adhesive wear , as indicated by SEM analysis of theworn surface.
