| Description |
Iron and its alloys acquire stability because of the phenomenon of passivity. Though several theories, models and
experimental works on passivity have been published in the literature, the mechanisms underlying the stability
of the passive oxide over the metals remain still a mystery. This review presents recent developments on theoretical
and experimental results besides the literature available in other reviews and critically reviewselected experimental
results on iron/electrolyte system and theoretical developments in general and specific to iron by
invoking high fieldmodel,modified high fieldmodel, point defect model (PDM), variants of PDM(VPDM), diffusion
Poisson coupled model (DPCM), density functional theory based atomistic model. The experimental and
model-predicted dependencies on applied voltage, pH, chloride and temperature are also presented and
discussed.
