Inspiration of reinforcements, manufacturing methods, and microstructural changes on wear behavior of metal matrix composites-a recent review

The Metal Matrix Composites (MMCs) are increasingly replacing the commercial alloys in engineering components and undergoing intense analysis in the development of advanced composite structures. The metal matrix composites exhibit superior mechanical and tribological behavior than alloys in wear critical applications. Profound research works have been carried out in manufacturing the MMCs for improved friction and wear behavior. This study highlights the recent investigations from the perspective of wear behavior of MMCs. The effect of reinforcements and manufacturing processes of composites on wear behavior is elaborated. The significance of mechanical factors such as normal load, sliding speed and sliding distance is explained. The wear mechanisms observed in MMCs and studies on sub surface damages of composites are reported.
