Profilometric Analysis of Worn Surface of Bronze, Iron and Iron Composite Samples, by Pin-on-Disk Method

Abstract

In this study are presented the results of profilometric analysis for the wear of bronze materials, cast iron and composite materials. These materials were tested under dry wear conditions, using "pin-on-disk" method on a UMT-2 tribotester at a room temperature and relative humidity of 30-45%. The tests were carried out with load of 30, 40 and 60 N at a linear speed of 0.815 m/s. The resulted traces of wear were examined with a Surtonic 3 + profilometer that has Talyprof software installed on, trademarks of TAYLOR HOBSON (United Kingdom) company. The obtained results allowed for a tribological analysis of the materials and their classification from the tribological point of view.
