摘要: Abstract Aluminium and its alloys have an ever growing demand in many industries such as aerospace, automotive due to their high strength weight ratio corrosion resistance. Our current work focuses on synthesis tribological studies of precipitation hardened Al 6061–Gr p –granite dust hybrid composites. Liquid stir casting technique is used for synthesis, hardening treatment imparted maximising the hardness before subjecting two-body sliding wear tests. The variation different levels load, speed composition along with SEM micrographs worn surfaces has been investigated. Hybrid combinations granite (2 wt% 4 wt%) graphite (2 wt%) show higher tensile strength, significantly improved resistance compared base alloy.
