The variations of the equivalent parallel resistance and capacitance of anodic films formed on Ta and Nb in varying concentrations of H2SO4 suggest that the volume of film formed per coulomb is much greater in 100)~, acid, although the dielectric constant is substantially unchanged.

Abetract-The anodic passivation of iron was examined with respect to the degree of proton hydration as well as the acid structure. The investigation was based on the electrochemical tneasurements, XPS study and sulphur dioxide analysis. When acid concentration is low, the passivity of iron is a resu

Current-potential curves drawn in different polarization conditions in the range -750 to + 500 mV/SCE show that two oxide films can be developed on zircaloy 4 in concentrated sulphuric acid media (70 wt %). The prepolarization times and conditions, the potential sweep direction and the temperature a
