Abstract The effect of magnetic feild and Cl- on anodic polarization behavior of iron in neutral 0.5mol/L Na2so4 solution was studied using potentiodynamic method. It was shown that iron in Na2SO4+Cl-solution exhibited active- passive-transpassive characteristics in the presence or absence of magnetic field, although Cl- in the solution would hinder the formation of passive layer. The applied magnetic field would cause shift of passivation potential Ep and flade potential EF towards noble direction, increase the critical current density for passivation imax and the passive current density imin, and narrow the passive region. A synergistic effect of imposed magnetic field and Cl- on breakdown of the passive layer was reported.
