Corrosion resistance and specific finctional properties (dielectrical and decorative properties, adhesion, wear resistance) of aluminium alloys can be improved by su&ace treatments as electrochemical or chemical conversion reaction. The purpose of this study is to discuss the applicability of spectroscopic ellipsometry (SE) and electrochemical impedance spectrometry (EIS) for the characterizati...
