Abstract

This paper aims to investigate the effect of varying the hardness of both sliding bodies on the operating wear regime. Unlubricated sliding wear tests were performed using a pin-on-disc configuration. The friction coefficient was monitored during the wear tests, and the variation of mass loss of bodies as a function of sliding distance was obtained to estimate the steady-state wear rate. The results showed that the operation of mild and severe wear regimes was influenced by the initial hardness of materials. Under the high pin hardness conditions, a decrease in the disc hardness promoted the severe wear regime operation prior to the action of a mild wear regime. Under the low pin hardness conditions, a severe wear regime was established. When the harder disc was tested, a mild wear regime was observed. Copyright (C) 2012 John Wiley & Sons, Ltd. (AU)
