Mechanical and Wear Behaviour of Nano-Fly Ash Particle-Reinforced Mg Metal Matrix Composites Fabricated by Stir Casting Technique

In recent years, magnesium-based alloys and composites have great attention in automobile, structural, biomedical industries due to their desirable characteristics such as lower density, low elastic modulus, high specific strength, better damping properties, excellent castability. The pure magnesium was used a matrix material reinforced with fly ash fillers of different compositions weight percentage 2.5%, 5%, 7.5% compare the magnesium. three weights (wt%) ash/Mg samples were prepared using bottom pouring stir casting method. Fabricated sliding wear mechanical behaviour (ASTM standard) studied. Wear, tensile, hardness results portray that 7.5 wt% possess elongation good resistance. tensile strength values improved by 42% sample 4 compared Mg. Hardness also 21% rate coefficient friction are reduced increased reinforcement. SEM images display casted magnesium’s morphology wear-tested samples’ worn surface characteristics.
