Wear Characteristics of Al 6061-Tib2 Metal Matrix Composite Developed by in-Situ Technique
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2019, Vol 9, Issue 4
Abstract
Metal Matrix Composites (MMCs) are extensively used in structural, automobiles and aerospace employments because of their enhanced mechanical characteristics. Wear tests are essential to study the performance level of MMCs used in various engineering applications. The joined special property of stir casting and in-situ system shaped Al6061- TiB2 composites, with dissimilar reaction holding periods from 0 to 60 minutes in steps of 15 minutes. Wear tests have been carried out to find the wear characteristics of both, the matrix alloy Al 6061 and the composites produced by the introduction of the reinforcement phase, and TiB2 using the in-situ method by adding halide salts K2TiF6 and KBF4 in to the liquefied state at 850°C with dissimilar reaction holding periods. Pin-on-disc device have been used for the testing purpose under different applied loads with different reaction holding times. The results show that the rate of wear of all composites is lesser than that of the matrix amalgam. The incorporation carried out by TiB2 in Al6061 alloy improves the wear characteristics.
