Abstract
Ceramic matrix composites of Al2O3-SiC-(Al, Si) have been fabricated by directed melt oxidation of aluminum alloys into SiC particulate preforms. The proportions of AI2O3, alloy, and porosity in the composite can be controlled by proper selection of SiC particle size and the processing temperature. The wear resistance of composites was evaluated in pin-on-disk experiments against a hard steel substrate. Minimum wear rate comparable to conventional ceramics such as ZTA is recorded for the composition containing the highest fraction of alloy, owing to the development of a thin and adherent tribofilm with a low coefficient of friction.
