## 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)
The anodic film studied was formed on Pb + 9at.%Bi at 0.9V (vs. Hg/Hg,S03 in 4.5 M H, SO, solution (25Β°C). The change of the phase composition of the anodic film during reduction at -0.91 V (vs. Hg/Hg,SO,) (slightly more positive than that of the reduction potential of PbSO,) was determined by X-ray
