In this work, dry sliding wear properties of Al 7075 Al 7075+ 5 wt.% SiC, Al7075 + 5 wt.% SiC + X wt.% graphite (X=5-10) hybrid nano-composites were developed by the principle of powdered metallurgy (P / M). Al 7075 hybrid nano-composites are highly promising materials that would be desirable for a wide range of applications. Under dry sliding conditions, the tests were carried out on a pin-on-disk machine was used to assess the loss of wear on base metal, composite and hybrid composites were calculated by different normal loads (5–20 N), and sliding speeds (0.5 – 2 m/s) and sliding distances (500–2000 m). Micro-structural examination of base metal and composites were investigated using an Optical Microscope (OM) and scanning electron microscope (SEM). The hybrid nano-composites revealed those greatest improvements in tribological results with 5 wt. % Silicon Carbide and 10 wt. % Graphite. Main wearing mechanism for hybrid composite materials has been established to form lubricating layer on both the surface and specimen. From experimental outcomes, it has been found that wear resistance tends to increase as weight percentage of the reinforcement increases.
