Corrosion Resistance Analysis of Al-Cu, Al-Zn and Al-Cu-Zn Alloys

Abstract:

Anticipating an alloy's corrosion resistance is essential to avoid product failure and reduce costs. Research and analyze the corrosion resistance of Al-Cu, Al-Zn and Al-Cu-Zn alloys based on the analytical balance of the elements according to weight, thermodynamic, metallurgical rules on metal alloys, kinetic and other properties. The purpose of this study is to determine the corrosion resistance of Al-5-wt% Cu, Al-5-wt% Zn and Al-5-wt% Cu-5-wt% Zn alloys based on the analytical calculation. Based on the analytical calculation results, the Al-Zn-Cu alloy has the best corrosion resistance with a corrosion rate of 0.4375 mmpy. Next is the Al-Cu alloy with a corrosion rate of 0.4634 mmpy. While Al-Zn alloy has the lowest strength with a corrosion rate of 0.4828 mmpy. Based on standard EMF potential values for these three alloys. Al-Zn alloys are most active with an value of-1.61 V, followed by Al-Zn-Cu alloys with an value of - 1.60 V, and the noblest Al-Cu alloy has the most positive value of-1.56 V. Faraday's law to get corrosion rates of the anode and cathode materials. In the third reaction, the exothermic alloy has a positive value of so the exothermic reaction occurs.
