Aluminum and its alloys are used for aerospace and automobile applications because of their high specific strength. However, they exhibit poor wear resistance which limits their usage in many applications. To overcome this, in this work, aluminum has been reinforced with boron carbide (B4C) and graphite using friction stir processing, thus, producing a hybrid aluminum matrix composite. This composite exhibited two times increase in the hardness (61 HV) as compared to the unreinforced matrix. The tribological performance of this composite was evaluated using a reciprocating sliding tester at different loads ranging from 1.96 to 5.88 N. To understand the wear characteristics, ex-situ analysis was performed on the worn surface of the processed composite using scanning electron microscope (SEM) and optical profilometer. The synergistic effect of B4C ceramic and graphite reinforcements provided excellent tribological properties in both the abrasive and adhesive wear regimes with a 49 improvement in wear resistance, especially at higher loads. © 2021, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
