Effect of Al2O3 and Fly Ash Addition on Mechanical, Wear and Corrosion Properties of Al-Mg-Si Base Alloy

Abstract

The aim of this study is to studding the effect of addition of alumina and fly ash with the particles size 106µm and different weight rations (2:2, 2:4, 4:2) to aluminium-magnesium-silicon alloy on microstructure, mechanical properties, corrosion resistance, and wear. The vortex technique was used to prepare the composite material. The microscopic structure was also examined using optical microscopy and mechanical tests (hardness, tensile strength, yield strength and elongation) and wear test. The results showed that the composite material the containing (2% fly ash and 4% alumina) had the highest tensile strength (119 Mpa), yield strength (76 Mpa) and hardness (89 kg \ mm2), while it has the lowest ductility (5.3%). It was also found to have the lowest wear rate (1.8* 10-6gm \ cm) and the highest corrosion resistance.
