dc.description.abstractThe 2024-T3 and 7050-T7 aluminium alloys electrochemical behavior has been studied in NaCl 5% neutral solutions and 0,1M concentration containing NO 3 - or NO 2 -. The current job supports corrosion research on aluminium alloys used in aeronautic industry. Open circuit potential, polarisation curves and electrochemical impedance spectroscopy techniques have been used. In chloride solutions, alloys corrosion takes place through a pitting mechanism. Added anions to aerated solutions do not possess inhibition effect. In deaerated solutions, nitrite has diminished anodic dissolution rate, probably by incorporating this anion in the oxide and/or hydroxide film.en
