During the last two decades, metal matrix composites (MMCs) have emerged as an important class of materials for structural, wear, thermal, transportation and electrical applications. Metal matrix composites (MMCs) possess significantly improved properties including high specific strength; specific modulus, damping capacity and good wear resistance compared to unreinforced alloys. Aluminium Metal Matrix Composites (MMCs) sought over other conventional materials in the field of aerospace, automotive and marine applications owing to their excellent improved properties. These materials are of much interest to the researchers from few decades. These composites initially replaced Cast Iron and Bronze alloys but owing to their poor wear and seizure resistance, they were subjected to many experiments and the wear behaviour of these composites were explored to a maximum extent and were reported by number of research scholars for the past 25 years.
In the present investigation, we have chosen aluminium as a matrix phase and titanium oxide as a reinforcement phase. The aim of our project is investigate the wear behaviour of aluminium metal matrix on different amount of reinforcement. The titanium oxide, 5%, 10%, and 15% weight of aluminium was used to make three different specimen. Among all the fabrication process we choose stir casting because stir casting process are simplest and cheapest. Magnesium (4% by weight) was added in molten aluminium to improve the wettability. After fabrication; the composites have been characterized for their wear behaviour to see the suitability as a wear resistant material. Wear test was performed as a function of sliding distance, applied load, sliding velocity with the help of Pin-On-Disc wear test machine.
