Prediction of Specific Wear rate of Glass and Bronze Filled PTFE Composites

Abstract

PTFE and its composites are steadily gaining ground over metals in the field of engineering applications in tribology. An attempt has been made to study the influence of wear parameters like applied load, sliding speed ,sliding distance on the dry sliding wear of PTFE+15% bronze ,PTFE + 25% glass and PTFE + 30% bronze composites. Wear behavior of the specimen was investigated by using the Pin ON Disc apparatus at ambient condition. Parameters are set for three different levels and in optimum possible combination by Taguchi experimentation design array. The results of experiments are presented in tables and graphs which show that the addition of bronze and glass filler to PTFE decreases wear rate significantly and there is marginal increase in coefficient of friction. Wear rate is obtained as a response of experimentation and then further analyzed in design expert software. At the end all three materials are compared on the basis of wear rate and coefficient of friction.
