passivation potential

in electrochemical corrosion
https://doi.org/10.1351/goldbook.P04444
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.
