passivation potential

in electrochemical corrosion
The most negative electrode potential at which the passivating film is formed. The passivation potential is equal to or more positive than the equilibrium potential of formation of the phase constituting the film. Usually, the corrosion current goes through a maximum at the passivation potential.
