Experimental Investigation on Friction and Wear of Stainless Steel 304 Sliding Against Different Pin Materials
Nov 08, 2016

In the present research, friction coefficients of stainless steel 304 (SS 304) sliding against different

pin materials are investigated and compared. In order to do so, a pin on disc apparatus is designed and

fabricated. Experiments are carried out when different types of pin such as aluminum, gun metal, copper and

brass slide on SS 304 disc. Experiments are conducted at normal load 10, 15 and 20 N, sliding velocity 1, 1.5 and

2 m/s and relative humidity 70%. Variations of friction coefficient with the duration of rubbing at different

normal load and sliding velocity are investigated. Results show that friction coefficient varies with duration of

rubbing, normal load and sliding velocity. In general, friction coefficient increases for a certain duration of

rubbing and after that it remains constant for the rest of the experimental time. The obtained results reveal that

friction coefficient decreases with the increase in normal load for all the tested pairs. On the other hand, it is also

found that friction coefficient increases with the increase in sliding velocity. Moreover, wear rate increases with

the increase in normal load and sliding velocity for all sliding pairs. The magnitudes of friction coefficient are

different for different material pairs depending on normal load and sliding velocity.
