Corrosion behavior of Al–3.0 wt%Mg alloy in NaCl solution under magnetic field

Effects of magnetic field and rare earth addition on corrosion behavior of Al-3.0 wt% Mg alloy

“…In order to improve the corrosion resistance of Al-Mg alloys, many attentions have been paid to the alloying technology [17][18]. In our previous work, mischmetal (37.3 wt.%La, 61.5 wt.%Ce) has been used to improve the corrosion resistance of Al-3.0 wt.%Mg alloy [19] and the corrosion behavior of Al-3.0 wt.%Mg alloy under applied magnetic field has also been studied [20]. It indicated that 0.4 T horizontal magnetic field would increase the pitting corrosion potential (E pit ), decrease the corrosion current density (i corr ), 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.…”
