6063 aluminium alloys were AC anodized in molybdate containing and molybdate free sulphuric acid solutions. The total impedance of the oxides produced in molybdate containing solutions decreased faster in 0.01 N HCl and after 8 days, following the dissolution of oxide film in 0.01 N HCl, the pits produced on the aluminum substrate surfaces were shallower and larger.
