Abstract
Electrochemical investigations on aluminium alloy corrosion in a sodium chloride solution have been performed by potentiostatic and potentiodynamic (electrochemical impedance spectroscopy) methods. Measurements have been obtained after mechanical polishing or electrochemical stripping in deaerated or not solution. All the results are strongly depending on the pretreatments that are undergone in the laboratory before the experimental measurements. Mechanical polishing induces huge effects on the surface of the analysed samples and a long time is necessary to avoid the effects of this treatment; instead, an electrochemical cleaning does not modify the surface and results can be regarded more rapidly as significant of the surface with higher reproducibility.
