Fig. 7. Current density distribution based on: (a, c) OCP after 24h in a 3.5% NaCl; (b, d) OCP directly before starting the potentiodynamic test. Exchange current density = 100 A/m 2 (default value in COMSOL).

Fig. 8. Current density distribution based on: (a, c) OCP after 24h in a 3.5% NaCl and calculated exchange current density; (b, d) OCP directly before starting the potentiodynamic test and calculated exchange current density.

Firstly, the current densities calculated by the models using experimentally obtained exchange current density values closely align with those obtained from the potentiodynamic data. They are 100 times lower than those
