Physical and Tribological Behaviour of Dual Particles Reinforced Metal Matrix Composites

Metal matrix composites (MMCs) have been an active area of research and scientific investigation for past few years, but only in recent times, MMCs have become realistic engineering materials. In the present study, physical and tribological performance of graphite and alumina particulates reinforced AA6351 matrix composites were examined experimentally. These final composites are produced through liquid metallurgy process. To examine the worn surface morphology of the composite was evidently exposed by scanning electron microscope (SEM) technique. The experimental results expose the tribological properties of composites increased with inclusion of filler reinforcements.
