“Wear Behaviour of Titanium Alloys When Subjected to Different Speed and Load Levels”

Abstract

Titanium and Titanium alloys are widely used for aircraft as a material having light weight, high strength and corrosion resistance. The titanium and its alloys are compatible with carbon fibre reinforced plastic components with respect to corrosion and thermal behaviour. Response of Titanium grade 2 and grade 12 at different speed during sliding is to be studied. The literature survey shows inadequate studies on wear response of these alloys. Experiments using pin on disc test rigs were conducted. Speed level of 500rpm, 1000rpm, and 1500 rpm were used. The sliding was found to be sensitive to sliding speed. As speed increases from 500 rpm to 1000 rpm the coefficient of friction increased. At speed of 1500 rpm two steady phase of sliding identified. In one of the steady phase the coefficient of friction was found to be more than the coefficient of friction at 1000 rpm. Where in another steady phase of sliding the coefficient of friction was found to be comparable or less then the coefficient of friction at 1000 rpm.
