Influence of reinforcement on the wear properties of Aluminium-12%Si (LM6) reinforced with Boron Carbide (B4C) particles (quantity from 3 to 12wt% in steps of 3wt%; size 40–80μm) was investigated by a computerized pin-on-disk wear test rig under dry sliding conditions. Copper chill was used. Castings were prepared using dry sand moulds and B4C particles were introduced into the matrix using Vortex-Route Method. Test results have shown that the wear properties of these developed composites were appreciably influenced by the chill and reinforcement. It was found that 9wt% of B4C particles in Aluminium-12%Si (LM6) alloy exhibited the least wear rate. An attempt to analyze and evaluate the wear properties of these developed composites with respect to chill, reinforcement and microstructure is made.
