Abstract
In this article, the heat treatment and dry sliding wear behaviour of Al-based AA6063 alloy reinforced with both TiC and Al2O3 ceramic particles were studied. The particles were synthesized by self-propagating high temperature synthesis (SHS) technique. The prepared composite alloy contains 5 vol. % Al2O3 and 5 vol. % TiC particles. The composite alloy was prepared by vortex method. To attain the peak hardness values of the alloys, age hardening behaviour of the monolithic alloy and also the composite alloy was investigated. The wear tests were performed at room temperature using a pin-on-disk type apparatus. The results showed that the addition of TiC and Al2O3 particles increases the hardness of the AA6063 Al alloy and at the same time accelerate the aging kinetics. The sliding wear properties of AA6063 Al alloy was significantly improved by the addition of TiC and Al2O3 particles.
