초록

Because of excellent mechanical properties, such as good friction coefficient and heat resistance characteristics, PTFE parts have been widely used in the industries. However, the poor wear resistance of PTFE has been a main problem limiting wider applications. In this study, to improve the poor wear resistance of PTFE, porous PTFE composites were prepared by mixing additives(sodium bicarbonate and graphite) with PTFE powder. The friction coefficient, wear resistance and lubricating property of porous PTFE composites were measured and the results were compared with those of untreated PTFE.
