Metal matrix composites, produced by stir casting method, have more advantages when compared to other methods. Aluminium alloy Al6061 was reinforced with various percentages of TiB2 particles by using high energy stir casting method. The characterization was performed through EDS and SEM. The mechanical behaviours like hardness, tensile and wear were investigated. Wear experiments were conducted by using a pin-on-disc wear tester at varying load to evaluate the tribological property of Al6061-TiB2 composite. The wear mechanism was studied through SEM. In this study revealed that the addition of TiB2 improves the wear resistance of aluminium composites. The results showed that the mechanical properties, such as tensile strength, wear resistance and hardness increased by the percentage of TiB2 present in the samples when compared with base aluminium alloy. |
