Two-body abrasion wear rate of AA6061 aluminium alloy, AA6061-2SiC nanocomposite, and AA6061-2SiC-2Gr hybrid nanocomposites were studied using a pin on disc machine at various applied normal loads 5-20 N and 50-150 µm abrasive grit size by maintaining a constant sliding distance of 120 m. Morphology of fabricated materials, worn surfaces of tested specimens, and abrasive grit papers were analysed under a scanning electron microscope. The wear rate of the AA6061-2SiC-2Gr hybrid nanocomposite was found to be less than that of AA6061 alloy and AA6061-2SiC nanocomposite. The wear rate decreased by 19% for 50 µm, 28.2% for 100 µm, and 22.5% for 150 µm at an applied normal load of 20 N and 120 m sliding distance for Al 6061-2SiC-2Gr hybrid nanocomposite compared to base alloy.
