Characteristics Investigation on Aluminium/Diamond Composites Fabricated Through Powder Metallurgy

Composites made from metal matrix materials have been widely used in aerospace, automotive applications. Alloys based on aluminium are widely used because of their excellent combination of strength, lightweight, and corrosion resistance. A hybrid composite comprising of aluminium powder and diamond powder was investigated in this study. An alloy based on aluminium was created through powder metallurgy. A hybrid composite of Al and an Al metal matrix reinforced with diamond particles contains 1% diamond and 3% diamond. ASTM standards were used to investigate mechanical and wear properties. The results revealed that 3 weight per cent of diamond reinforced with aluminium increased wear resistance by 60.66% over pure aluminium without diamond. When 3% Diamond is mixed with 97% aluminium, the compressive strength increases by 87.27% compared to pure aluminium. Comparatively, a composite of 97% aluminium and 3% diamond has the maximum hardness value. Examining the surface morphology of hybrid composites was demonstrated via SEM images.
