Özet

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.
