The study aims to examine the fabrication, mechanical properties, and tribological behavior of aluminum 6061 hybrid composites reinforced with silicon carbide and graphite.
Composites fabricated using liquid-state stir casting and permanent mould casting.
Microstructural characterization performed using optical microscopy and scanning electron microscopy (SEM).
Mechanical properties evaluated including hardness and tensile strength, with tribological testing on a pin-on-disc tribometer.
Incorporation of 10 wt% SiC increases ultimate tensile strength by 26.1%.
Wear rate decreases by 49.7% relative to unreinforced Al 6061 matrix.
Tribological performance of hybrid Al-SiC-Gr composite indicates suitability for applications requiring wear resistance and lubricity.
