Abstract
In the sliding pairs, friction and wear are the core reasons for energy losses that reduce the efficiency of the mechanical systems. This thesis presents an experimental study to predict the frictional and wear behaviour of AISI 4340 steel under lubricated conditions. The experiment was conducted on a pin on disc machine during which EN-31 steel disc was used as a counter surface. The tribological characteristics of AISI 4340 material were observed under different loads varied as 30N and 90N at a fixed sliding distance of 1500m at a continuing speed of 1.0,1.5,2.0,2.5 m/s. it had been found that variation of load and sliding distance play a crucial role in frictional force and wear behaviour of the gear material. The wear and tear of AISI 4340 steel found to be increased with the rise of sliding distance. Load is that the most significant factor which liable for wear loss. The result showed that irrespective of the loads the COF minimum at 2.0 m/s sliding speed and then it increases with the increase in sliding speed.
