organic and non-organic nature. As a result, we found the
differences in stationary potentials and anode-current
density. Findings of the research showed that the 18 %
W–Zr alloy was the most electrochemical active in the
presence of fluoride ions in alkaline electrolyte. This fact
was proved by the shifts of electrode potentials on polariza-
tion curves to negative values and by growth of anodic
current maximum
