Abstract

The effect of magnetic field on the anodic process of iron in Na₂CO₃ solution containing chloride was studied by means of potentiodynamic polarization and potentiostatic polarization. The results showed that the magnetic field reduced the current density in passivation zone of polarization curve. The magnetic field increased the current density in over-passivation zone of polarization curve at lower scanning rate, and decreased the current density in high potential range of over-passivation zone at higher scanning rate. The magnetic field reduced the current density in the lower potential range of passivation zone of polarization curve. In the higher potential range of passivation zone, the influence of magnetic field on current density was not obvious. The acceleration effect of magnetic field on anodic reaction in over-passivation zone decreased with the increase of polarization potential.
