Abstract
In recent years, Aluminum alloys reinforced with non-metallic and metallic materials has emerged as an important class of engineering materials since they have excellent mechanical qualities. However, newer compositions are required to be explored for specific requirements of the industry such as wear resistance. In this paper, aluminium alloy (Al-2024) was embedded with a blend of SiC/Fly Ash/Graphite in various compositions using the stir casting method. Wear and friction characteristics of the prepared compositions were evaluated on a pin-on-disc tribometer. The specimens were tested at a constant load of 20 N and a sliding speed of 1.6 m/s for a sliding distance of 800 m. The wear mechanism was evaluated using a scanning electron microscope. The wear rate of the 15% reinforced sample was recorded to be the lowest among all the developed composites and was found to reduce by 69 times as compared to the Al-2024 alloy matrix alone. The wear mechanism was a combination of abrasive and adhesive wear mechanisms.
