Study of Tribological analysis of PTFE and its filler using Taguchi Approach

Abstract

Polytetrafluroethylene (PTFE) is self-lubricating tough, waxy, non-flammable synthetic resin produced by the polymerization of tetrafluroethylene. Pure PTFE is widely used as bearing material and many such applications which is subjected to high wear rate, can be reduced by adding suitable fillers. PTFE exhibits poor wear and abrasion resistance, leading to early failure and leakage problem in the machine parts. This paper present the experiment l analysis of three composites (PTFE + 35% Carbon, PTFE + 35% Glass, PTFE + 35% Bronze) showing how properties of PTFE can be improved by the addition of filler content. The effects of varying load, sliding distance, sliding velocity and filler content on wear in PTFE are studied. The results of experiments are proved that the wear is strongly influenced by the composition of filler content.
