Ceramic-reinforced aluminum alloys offer distinct advantages over the base alloy. In this project, aluminum-based composites containing silicon carbide particle reinforcements were fabricated using an infiltration technique. Silicon carbide particles were incorporated into molten Al-10% Mg-5% Si (wt%). The resulting materials were characterized using optical and scanning electron microscopy to understand their microstructure. Phase analysis was conducted using X-ray diffraction. Vickers microhardness measurements were also obtained. The abrasion behavior of these composites was studied and compared to the matrix aluminum alloy as well as gray cast iron.
