Wear of a rough disc in dry sliding contact with a smooth ball: experiment and modeling

Abstract The main objective of this work is to model wear a disc which was subjected dry contact with ball in unidirectional sliding. Tribological tests sliding pairs were carried out using tribological tester T-11 ball-on configuration. Stationary balls made 100Cr6 steel hardness 62 ± 2 HRC co-acted rotating discs 42CrMo4 40 2HRC. Discs machined by lapping, grinding, milling, and vapour blasting. values the Sq parameter surfaces between 0.1 5.86 µm. Wear volumes lower for bigger roughness heights. simulation conducted on basis repetitive surfaces. Strong correlation achieved modeled measured volumetric levels.
