Author(s): Isha Srivastav, Gaurav
Abstract: The tribological behaviour of Al 6061 at a constant load and varying sliding speeds was investigated experimentally using CSM made pin on disc high temperature Tribometer apparatus. The tests were carried out using at a constant load of 2N and varying sliding speeds of 2 cmsec-1, 4 cmsec-1, 6 cmsec-1 and 8cmsec-1 respectively. Another test were carried out at a constant load of 2N, constant sliding speed of 2cmsec-1 and temperature of 100 ºC temperature. Effect of different sliding speed on rubbing surface was investigated. Optical microscope were used in order to study the wear Track of the samples. The depth of penetration of 100Cr steel ball into the disc at all speeds and temperature was noted. It has been found that friction coefficient decrease with the increase of sliding velocity and it increases with the increase of temperature.
