Description
Friction and wear properties of Al-25Zn-3Cu-3Si alloy were investigated over a range of pressure and sliding speed using a pin-on-disc test machine. The friction coefficient of the alloy increased with sliding speed, but decreased with increasing pressure up to 1.5 MPa, above which the trend reversed. However, the temperature and wear volume of the alloy increased continuously with increasing pressure and sliding speed. A fine-grained layer and a region with flow lines were observed underneath the surface of the wear samples. The formation of these regions was related to smearing of wear particles and heavy deformation of surface material, respectively. (C) 2010 Elsevier Ltd. All rights reserved.
