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
The rate of nucleation of the anodic oxide film on bismuth in 0.1 M NaOH is limited hy electrochemical reaction at the uncovered metal surface or surface diffusion to the periphery of a spreading oxide patch, not by incorporation into the growing lattice. Anodic oxide layers grown on bismuth consist
