Abstract:
The rate-controlling step for the corrosion of iron in ferric solutions is determined by electrochemical measurements under a magnetic field. A positive shift in open circuit potential and the increase of cathodic current by imposing a magnetic field indicate that the contribution of the mass transport process of reactive species to rate control. The corrosion rate of iron under open circuit conditions is controlled by both the mass transport step and the electron transfer step. There is a potential region in which the ferric reduction rate is fully controlled by the mass transport process, as indicated by the potential independence of the resulting current density from the magnetic field.
