Tribological Studies on Aluminum-Based Particulate Reinforced MMCs. Literature Review, Fabrication, Physical, Mechanical and Tribological Studies of Aluminum based Metal Matrix Composites

      Аннотация: Aluminum (Al) Metal Matrix Composites (MMCs) are being used in place of cast iron and steel in automobile, mining and mineral sectors due to their lightweight and high strength. In automobile, aerospace, mining and mineral sectors, there exist situations where two mating parts are in sliding contact with each other. Due to the relative motion, there is an inevitable loss of material. In certain situations, if the extent of material is beyond a critical limit, there are possibilities of catastrophic failure of the components. Wear is a complex phenomenon and the most important reason for the damage and consequent failure of machine parts. This book describes the extensive literature review of the various researchers work on the studies of Al-MMCs. Further, the fabrication of MMCs, of Al6061-SiC, Al6061- Al2O3, Al7075-SiC and Al7075-Al2O3 MMCs. The composites were developed by liquid metallurgy technique via stir casting method which is economical. The fabricated MMCs were subjected to various studies like physical, mechanical and tribological properties along with the OM and SEM studies on the alloys and composites. The obtained results of the MMCs were presented and discussed.
