Mechanical and Wear Behavioral Assesment of Al 7075-Al2o3 Metal Matrix Composite

Abstract

Aluminum alloys are wide utilized in part and automobile industries because of high strength to low weight ratio and their smart mechanical properties like higher corrosion resistance and wear resistance, low thermal growth as compared with different metals. Aluminium 7075 alloy is chosen as matrix alloy and Al2O3 as a reinforcement. The amount of Al2O3 particles is varied with weight fractions of 2%, 4%, 6% .The objective of the paper is to enhance the mechanical and tribological properties like impact strength, hardness, wear of Al7075 alloy based metal matrix composite. The result were found that with increase in reinforcement content of Al2O3 in Al7075 alloy improve the mechanical properties and wear resistance.
