temperature was studied and the effect of an external magnetic field oriented both parallel and perpendicular to electrode surfilce was investigated. Cyclic potentiodynamic and potentiostatic polarization tests were carried out. Anodic breakdown potential of+1.4 V (w. AglAgCl) obtained in the absence of magnetic field, decreasing to +1.1 V in the presence of a 0.05 T parallel magnetic field. The perpendicular magnetic :field actually did not affect thebreakdown potential. Applying of an external magnetic field, independent of its orientation, shifted the repassivation potential 100 mV in the positive direction. SEM microscopy observations of sample s1.u’:taces indicated that applying of magnetic field results in some variations in the pit shapes and their sizes.
