Abstract
Abrasive wear of as-cast Al-12 wt% Si alloy has been slid against SiC emery papers
(grits 120 and 220). The wear rate and wear mechanism as a function of bearing
pressure have been studied. The wear rate increased considerably with increasing the
size of abrasive material. Detailed analysis of worn surface showed the formation of
scratches and removal of debris particles by mechanism depended highly on bearing
pressure and to less extent on emery paper. Increasing the bearing pressure resulted in
the formation of debris without plastic deformation of the subsurface.
