.... Corrosion and passivation potentials are found to be significantly reduced due to the change in the cathodic reaction and the decrease in passivation kinetics under deaerated conditions. Energy-dispersive x-ray spectroscopy examination and scanning electron microscopy imaging indicate that no pitting...
