Fig.10 Formation of the effect of the salt layer (a), time-evolution of corrosion damage (see legend) with the earlier PD model (left side of the figure) and the newly proposed PD model (right side of the figure) (b)[86] (Red bonds in Fig.10a are temporarily paused as a result of saturation at nodes in the nearby solution, Ccrit—critical concentration of metal cations corresponding to metal repassivation, C—concentration of solid node)
