The current investigation focuses on the wear behaviour of an LM25 aluminum alloy that has been strengthened with boron carbide (B₄C) and graphite (Gr) particles using a stir casting manufacturing technique. In order to prepare the LM25 aluminum metal matrix composites (AMMCs), B4 C and Gr reinforcement are added in amounts of 2, 4, and 6 weight percent with different grain sizes (B₄C = 40 μm, Gr = 7 μm). The examination of the wear behavior, wear loss, and coefficient of friction (CoF) characteristics of primed samples was conducted utilizing a pin-on-disk wear test apparatus at room temperature. In order to evaluate the wear behavior of LM25-B₄C-Gr composites, loads of 10 N, 20 N, and 30 N, speeds of 6 m/s, and sliding distances of 2000 m were taken into account. The composites’ worn surface was inspected using a field emission-scanning electron microscope (FE-SEM). It was observed that the wear rate, CoF, and FESEM images of AMMCs were improved by the incorporation of reinforcing B₄C and Gr particles.
