ANALYSIS OF WEAR BEHAVIOR OF ALUMINIUM-7075 AND BERYLLIUM COMPOSITE

Aluminum alloys are widely used in aerospace and automobile industries due to their low density and good mechanical properties, better corrosion resistance, wear resistance and low thermal coefficient of expansion compared to conventional metals and alloys. These materials exhibit good mechanical properties and production cost is comparatively low. Hence they form a very strong contender in variety of applications. In this work, attempts were made to produce the Aluminum-7075 alloy composite by adding different amounts of Beryllium to the melt(5%,10%,15%). Wear studies in dry sliding condition for three different speeds and loads were studied. Comparison between the base aluminium-7075 alloy and the composite alloy were carried out. Simulation studies for wear has also been carried out. Temperature profile along the whole length of the specimen is generated; these are compared with the simulated ones, (ANSYSY workbench software has been used for this study).
