Title: Comparative study on the Corrosion Behavior of Aluminum Alloy 2011 in Different Acidic Media
Keywords: corrosion resistance, aluminum alloy, electrochemical measu

Abstract: Electrochemical study, aiming at comparing the corrosion resistance of aluminum alloy 2011 in three different acid solutions (H2SO4, HCl and HNO3) has been carried out by means of employing cyclic voltammetry, open circuit potential and a digital microscope. Potentiometric technique has been applied to determine the corrosion behaviour of the alloy in the three acid solutions and to study its passivity over time. The metal surface morphology has been studied using a digital microscope. The obtained results indicate that the aluminum alloy 2011 corrodes to a greater extent in a hydrochloric acid solution than it does in a nitric and sulphuric acid solution. The results from the potentiometric tests show the formation of more stable passive films in the sulphuric than in the nitric and hydrochloric acid solution.
