Abstract
The application of aluminum composites in automobile industry has gained significant attention of researchers over the last few years. The main reason for this is aluminum composites provides better mechanical and wear properties. The nano composites provide better thermal stability, wear resistance and weight reduction in automotive industry. The main objective of this study is to investigate the aluminum nano composite performance of piston rings. In this study, nano composites are prepared by alloying of Aluminum with other transition elements, which will produce a dispersion of Magnesium mixture a reinforcement particle within a nano structured aluminum matrix, at room temperature. Aluminum, Magnesium particles mixtures were mechanically alloyed during casting with different quantities mixed in the Al-Si mold and cooling in annealed atmosphere by using a cast iron die. The powder mixtures were produced with nominal composition of extra 5gm of Si, and 10 gm of Mg to Al-Si alloy, using powders of pure particles of Mg-Si. The performance of these nano composites was studied under various mechanical properties such as wear resistance, frictional force and hardness. It was found from results that al-mg nano composites provide better mechanical performance.
