Srinivasula Reddy I.Kaliveeran V.2021-05-052021-05-052019Materials Today: Proceedings , Vol. 27 , , p. 2688 - 2692https://doi.org/10.1016/j.matpr.2019.11.248https://idr.nitk.ac.in/handle/123456789/15051The present study focuses on understanding the variation of coefficient of friction over a period of time. At various sliding cycles, the coefficient of friction was noted from the well-controlled sliding experiments. Friction tests were conducted using Aluminium alloys (Al 6061 and Al 6082) with 10 N constant normal load and at sliding speed of 1.5 m/s. The detailed friction results have been presented and discussed to understand the influence of coefficient of friction on the contact tractions at the interface. The obtained friction results are compared with the results mentioned in literature, where reciprocating sliding experiments were conducted. From this comparison, it is concluded that the formation of oxide and nitride layers are dominant, when the friction tests are conducted using pin on disc setup. © 2019 Elsevier Ltd.
