Experimental Investigation of Tribological Properties of Cu/Al2O3/TiO2 composites

Abstract

Tribological properties play an important role in day to day life. Tribology includes study of friction, wear and lubrication. Tribology comes in picture when there is relative motion between two surfaces in contact. When there is relative motion between two surfaces in contact, there is loss of material rubbing each other. In order to minimize friction and wear, we can choose suitable lubricant. This project aims at fabricating pin on disc machine, preparing three composites made from copper, alumina and titanium dioxide by powder metallurgy process and conducting wear test for the three composites by help of pin on disc machine. By conducting the wear test, graphs are plotted between wear rate and sliding velocity. From the results obtained, effect of sliding velocity and composition of composites on wear rate of the three specimens were analysed.This investigation will help us to improve the tribological behavior of rubbing surfaces by varying their composition. The details of experimentation and analysis are given in the following context.
