Abstract
The effects of magnetic fields, solution composition and electrode potential on anodic dissolution, current oscillation and passivity of iron and copper were investigated by electrochemical measurements. Enhancing effects of magnetic field and solution acidity on anodic dissolution of copper in sulfate-bearing solutions were observed. The effects of magnetic field on anodic current oscillations of iron and copper during potentiodynamic polarization and potentiostatic polarization were observed. Synergistic effects of magnetic fields and anions on passivity breakdown of iron was analyzed. It is proposed that magneto-electrochemistry could serve a novel approach for investigating reaction mechanisms and kinetics for complex electrode systems.
