The Effect of Suspension Casting on the Properties of Fly-Ash Particle Reinforced Al Matrix Composites

The effect of suspension casting on the properties of fly-ash particle reinforced aluminum matrix composites is studied in this paper. The result shows that adding suspending agent with the same composition of aluminum matrix ,can improve the microstructure of aluminum matrix composites contain 5vol% fly-ash particle when addition temperature is 800°Cand addition quantity of suspending agent is 3%. The hardness and wear-resistance of fly-ash particle reinforced aluminum matrix composites can be increased by 13.10% and 20.10%.
