Abstract

The extensive applications of aluminium alloy in the automotive and aerospace industries promote the current research activity. The present research work focuses on the enhancement of the mechanical and wear properties of AA7050. The aluminium composites were synthesized utilizing the liquid metallurgy processing route, with titanium dioxide at different weight percentages. The microstructural analysis exhibited the increase in grain size and uniform scatter of reinforcement in the matrix material. Also, the properties of the AA7050 composite, such as density, hardness, tensile strength, and wear behaviour, were studied. The properties of AA7050 composite, such as hardness, tensile strength, and wear resistance, increased up to 5 wt.% titanium dioxide addition, and beyond that, it shows a reduction. The microscopic examinations on the AA7050 composite samples after the tensile test and wear test revealed failure modes.
