Abstract
A comparative analysis of the reactivity of nickel and its alloy with rhenium during their direct current polarization in sulfuric acid solutions (50–150 g/L, 25–60°C) is carried out. The regions of anodic potentials of their active dissolution and passivation are determined on the basis of the analysis results. The chemical compositions of the passivation films of electrode polarization are determined by X-ray photoelectron spectroscopy. The mechanism of film formation is established. The influence of the depolarizing ability of rhenium in the alloy composition on the depassivation of the alloy is revealed and evaluated.
