Abstract :

In this work, the effects of velocity of sliding, load and sliding distance on friction and  wear of PTFE composites with filler materials such as glass bronze and carbon are studied under wet conditions. The experimental work is performed on pin-on-disc apparatus in wet conditions (under the influence of water) and analysed with the help of Design-Expert software. Parameters are set for three different levels and in optimum possible combination by Taguchi experimentation design array. Wear rate is obtained as a response of experimentation and then further analysed in design expert software. Parametric relation is developed in the form of equation for each material composition. At the end all three materials are compared on the basis of wear rate and coefficient of friction in both dry and wet conditions. As graphical representation is the most user friendly way of interpretation of statistical data, three-dimensional graphs comparing wear rate of all three materials simultaneously under the influence of individual parameters namely load, sliding distance and sliding velocity are given in results. The results of experiments are presented in tables and graphs which show that the addition of bronze and carbon filler to PTFE decreases wear rate significantly and there is drastic change in coefficient of friction in wet conditions as compared to dry conditions.
