In recent decades, silicon nitride (Si3N4) and carbon fibres (Cf) have been the most popular candidate materials as reinforcements in the production of metal matrix composites (MMCs) due to their superior wear and corrosion resistance. Al6061 is the most sought after matrix alloy owing to its excellent formability among all class of aluminium alloys. Several researchers have reported on dry sliding wear and corrosion properties of cast composite with carbon fibres and silicon nitride as reinforcements but limited information is available related to the slurry erosive wear behaviour of hot extruded hybrid MMCs with carbon fibre as one of the reinforcement. In the light of the above, the current experimental work is aimed at investigating the slurry erosive wear behaviour of Al6061 dispersed with Si3N4 (6 wt %) and Cf (1 wt %) hybrid MMC after hot extrusion.
