Abstract
A new laboratory technique for obtaining a new metal surface is presented and used to investigate electrode reaction rates on stainless steel under potential control. The reactions examined were metal dissolution and oxygen reduction in NaCl solutions in the pH range 1–13.25. The mixed potentials and current densities were dependent on surface roughness. During abrasion, the heating effect and cold working were found to be small and there were practically no modifications of the metal surface. The dissolution rate at constant solution pH, was independent of the chloride content. The obtained kinetic data are discussed in terms of Fe steady-state dissolution and O 2 reduction mechanisms.
