At less negative potentials, the weakened Fe•••O interactions can lead to the destabilization of the passive layer, thereby increasing the likelihood of corrosion. However, it is important to emphasize that strong surface-oxygen interactions do not necessarily equate to the formation of a stable passive layer, as the process is far more complex than mere oxygen adsorption. The development of a stable passive layer depends on several specific factors, including mildly oxidizing conditions, an appropriate potential range, the composition of the electrolyte, and the formation of a continuous, dense oxide layer. Under highly negative potentials (strongly reducing conditions), the formation of a stable oxide film is limited. Instead, the surface may become saturated with adsorbed oxygen species, depending on their availability, which further complicates the stability of the oxide layer.
