n aircraft, compressor blades are subjected to severe wear because of high contact temperature and pressure. Ti-6Al-4V is
used as compressor blade for aircraft applications; however, its friction and wear properties have not been studied fully under
high stress and high temperature conditions. Friction and wear behaviour of Ti-6Al-4V against silicon nitride and alumina
have been studied under dry sliding conditions in temperature range of RT-400°C, using ball-on-disc universal tribometer. For
sliding distance test the wear rate of Ti-6Al-4V with alumina is less than the silicon nitride for entire range at 400°C. The wear
volume of Ti-6Al-4V increases with increase in sliding distance from 200 m to 1000 m against silicon nitride and alumina. For
Ti-6Al-4V, highest coefficient of friction (µ) 0.76 and 0.71 against silicon nitride and alumina was obtained at 10 N, whereas
minimum µ of 0.36 and 0.47 against silicon nitride and alumina was obtained at 20 N, these tests were carried out at 400°C.
For temperature test highest coefficient of friction (µ) 0.56 and 0.74 against silicon nitride and alumina was obtained at 400°C,
whereas minimum µ of 0.44 and 0.38 against silicon nitride and alumina was obtained at RT. Optical microscopy, SEM, EDAX,
and 3 D profilometery have been used to understand the friction and wear mechanism of tribopair. From these observations it
is concluded that wear of Ti-6Al-4V is minimum.
