Representative OCP (Potential (V vs SCE) vs time(s)) and PD curves (potential (V vs SCE) vs current(A/cm2)) of a galvanized DP590 steel. Annotations highlight locations where images of the sample surface are shown, i.e. (a) at the start of OCP, (b) at the end of OCP, (c) at Ecorr, (d) during hydroxide film growth, (e) after film growth is completed or just before breakdown of the film, (f) after film breakdown, (g) during film dissolution, (h) ~ 150 mV above the breakdown potential. Images show the formation and dissolution of the light colored Zn(OH)2 coating on the surface.
