The Effect of Electrolyte Anion Composition on the Corrosion Behavior of Cadmium, Bismuth, and Their Eutectic Alloy in Borate Buffers

Аннотация

The effect of borate anion concentration on the electrochemical corrosion behavior of Cd–Bi eutectic alloy in borate buffers with a pH of 7.4 is studied. The results for the alloy are contrasted with the data obtained for the individual metals. Borate species are shown to participate in the anodic dissolution of the three systems in question. We identified similarities in dissolution behaviors of the alloy and its electronegative component (cadmium).
