Abstract : Metal Matrix Composites (MMCs) are used in aerospace, transport, automotive, marine engineering due to their light weight with improved strength, stiffness and wear resistance. Wear is one of the reasons for the failure of the machine components. It is difficult to accurately predict the life of components due to wear, because, generally the wear rates are largely scattered. An attempt is made to study the Wear characteristics of Hematite (Fe2O3) reinforced Aluminum 6061 Metal Matrix Composites. The reinforcement is added in particulate form of 40-45 μm with an increment of 2% from 0% to 8% (by weight). Composites are fabricated by liquid metallurgy technique. The Microstructural study on as cast Al6061-Fe2O3 compositesreveals uniform distribution of reinforcement particles. The wear test was conducted on the specimens by varying speed from 200 - 400 rpm amp; load from 50 - 100 N. The wear rate was measured by the weight loss of the specimen. The results show that there is an increase in the wear resistance with increase in percentage of reinforcement. The wear factor has decreased 30 - 40% at 8% of reinforcement as compared to base matrix material. © 2017 Elsevier Ltd. All rights reserved.
