【 摘 要 】

Aluminum alloys such as 7075, which are extensively used in aircraft structures, render them highly susceptible to corrosion. Corrosion can adversely affect aircraft structural integrity since fatigue cracks can nucleate from corrosion pits and grow at an accelerated rate in corrosive environment. The engineering machines and mechanical components are subjected to fluctuating stresses, taking place at relatively high frequencies and under these conditions failure is found to occur. The main objective is to fabricate Metal Matrix Composite using stir casting machine and Surface Finish of AL7075 with Zirconium and SEM is analyzed. The Composite materials are aluminum mixed with different compositions of 1%, 2%, 3% Zirconium.
