The effect of presence of TiO2 and Fe2O3 micro-particles on the hardness, wear, corrosion resistance, and tensile strength of Al5083 alloy is investigated in this study. TiO2 and Fe2O3 micro-powders at different wt.% (0%, 2%, 4% and 6% each) were added as reinforcements into the aluminium matrix and the composite was prepared by stir casting. SEM images of the prepared samples exhibited an even spreading of reinforcements in the base material. The corrosion resistance, tensile strength, wear resistance and hardness of the base material was identified to be improved with increase in weight percentage of the reinforcing medium. However, at high wt.%, the tensile strength exhibited a lowering tendency due to the possible formation of agglomerates of the micro-particles within the material. The resistance of the base alloy against corrosion appeared to be substantially improved by the addition of TiO2 and Fe2O3 and the trend was positive with increase in weight percentage of the micro-constituents. Thus, addition of micro-particles like TiO2 and Fe2O3 can improve the mechanical as well as physical properties of Al5053, enabling it to find significant application in marine, automobile, chemical and aviation fields.

摘要

The effect of presence of TiO2 and Fe2O3 micro-particles on the hardness, wear, corrosion resistance, and tensile strength of Al5083 alloy is investigated in this study. TiO2 and Fe2O3 micro-powders at different wt.% (0%, 2%, 4% and 6% each) were added as reinforcements into the aluminium matrix and the composite was prepared by stir casting. SEM images of the prepared samples exhibited an even spreading of reinforcements in the base material. The corrosion resistance, tensile strength, wear resistance and hardness of the base material was identified to be improved with increase in weight percentage of the reinforcing medium. However, at high wt.%, the tensile strength exhibited a lowering tendency due to the possible formation of agglomerates of the micro-particles within the material. The resistance of the base alloy against corrosion appeared to be substantially improved by the addition of TiO2 and Fe2O3 and the trend was positive with increase in weight percentage of the micro-constituents. Thus, addition of micro-particles like TiO2 and Fe2O3 can improve the mechanical as well as physical properties of Al5053, enabling it to find significant application in marine, automobile, chemical and aviation fields.
