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. The field requir
The growth of multilayer oxide films on smooth platinum anodes in O-5 M HISOl has been investigated under the potentiostatic conditions where oxygen was evolved vigorously. The range of anodizing condition covered was : electrode potential, 207-2.22 V(nhe); 20-35ยฐC; duration up to 60 min. The growth
## Abstract The effects of samarium on the properties of the anodic Pb(II) oxides films formed on lead at 0.9 V (vs. Hg/Hg~2~SO~4~) in 4.5 mol/L H~2~SO~4~ solution were studied using linear sweep voltammetry (LSV), electrochemical impedance spectroscopy (EIS) and scanning electron micrographs (SEM)
