Mechanical and Corrosion Behaviours of Aluminum Metal Matrix Composite (Al 7075, Sic, & Zn)

Abstract

The aluminum based composites are increasingly being used in the transport, aerospace, marine, automobile and mineral processing industries, owing to their improved strength, stiffness and wear resistance properties. The mechanical properties of aluminum alloy based composites were investigated and analyzed. In this project, we have manufactured aluminum metal matrix composites in which Zinc used as an alloying element and Silicon carbide is the reinforcement materials. The aluminum metal matrix composites were manufactured by using stir casting method. The cast aluminum metal matrix composites were machined to required dimensions for testing. After that, mechanical tests were conducted on the composites prepared. The tests carried out are tensile test, Impact test, corrosion test and micro structure. The test results were studied and analyzed. The mechanical properties were determined and corrosion test was carried out.
