Abstract

The effect of magenetic field on anodic dissolution rate of iron in 0.2 mol/L sodium chloride solution was investigated by potentiodynamic polarization and potentiostatic polarization. The results showed that magnetic field accelerated the anodic dissolution rate of iron. The surface of electrode was macrsocopically uniform after potentiodynamic polarization in 0 T magnetic field. After potentiodynamic polarization in 0.4 T magnetic field, locally accelerated dissolution occurred on both sides of the iron electrode surface parallel to the direction of magnetic field. It took longer time for iron-electrode solution interface to reach the steady state in an applied magnetic field than that during anodic polarization in no applied magnetic field during potentiodynamic polarization. When potentiostatic polarization in 0 T and 0.4 T magnetic fields, the enhancement factor for anodic current density by the magnetic field was similar in a wide potential range.
