in electrochemical corrosion
The process of transition from the active to the passive state by formation of the passivating @F02366@. Passivation is achieved by an anodic current which at the respective @E01956@ must be larger than the maximum current, or by the presence of an oxidized substance in the neighbouring solution which passivates by being reduced (passivator).
