In this work the dependence of corrosion resistance of Al alloys AA 2024-T3 on sealing treatments was studied. AA 2024-T3 samples were anodized at 14 V in a bath containing sulfuric and tartaric acids. Anodized samples were sealed with four different treatments: hot water, vapour, hot water with salts and stirred hot water. Electrochemical Impedance Spectroscopy measurements were performed to estimate samples' corrosion resistance in a solution simulating sea water environment. Samples sealed in hot water showed the highest corrosion resistance.
