Fretting wear behavior of the Hardfaced structural steel under corrosive environment

Abstract

In this study, effect of hard facing on fretting wear behavior of structural steel under various environments has been investigated. As the first step hard facing of austenitic stainless steel AISI 308L was performed on structural steel by arc welding, microstructure and mechanical properties were investigated. In the second step, fretting wear test was carried out with different loads (10N, 20N and 30N) under various environments [temperature (27°C, 75°C, 125°C &175°C) and Salt water environment]. The result showed that the structural steel could be hardfaced by austenitic stainless steel AISI 308L with a reasonable quality of bonding by arc welding. Hardness of the structural steel enhanced by 30% by hardfacing of 308L. The fretting wear test result showed that in structural steel wear volume loss is significantly higher than the hardfaced steel under all environments used in the present study. Finally, an empirical relationship was also developed to predict the wear loss theoretically as a function of temperature & applied load at 3-meter sliding distance. © 2019 Elsevier Ltd.
