Abstract
6063 aluminium alloys were AC anodized in molybdate containing and mol ybdate free sulphuric acid solutions. The total impedance of the oxide s produced in molybdate containing solutions decreased faster in 0.01 N HCl and after 8 days, following the dissolution of oxide film in 0.0 1 N HCl, the pits produced on the aluminum substrate surfaces were sha llower and larger.
