Corrosion potential / V (SHE) =
Corrosion current density / A m−2 =
The cathodic reaction cannot drive corrosion of this metal at this pH. Corrosion will not occur.
The cathodic reaction has an equilibrium potential very close to that of the metal at this pH. The driving force for corrosion is small and so corrosion will be slow
