The influences of applied magnetic field on the corrosion behavior of Al-3.0 wt%Mg alloy in 3.5 wt% NaCl solution were investigated by electrochemical measurements, scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS). Stochastic analysis was applied to investigate the influences of applied magnetic field. The results indicate that the application of horizontal magnetic field of 0.4 T would increase the pitting corrosion potential ( E ), decrease the corrosion current density ( i ), prolong the pit initiation time, slow down the pit generation rate and inhibit the growth of pitting of the tested alloys in 3.5 wt% NaCl solution. The applied magnetic field would also change the mechanism of pit initiation of Al-3.0 wt%Mg alloy from A model (without magnetic field) to A + A model (with magnetic field). The intermediate product Al is the paramagnetic ion that would be influenced by magnetic field sensitively. [ABSTRACT FROM AUTHOR]
