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