Abstract

Effect of chlorides on the passive film formed on iron in borate buffer has been investigated by Auger Electron Spectroscopy (AES) and coulometric methods. AES measurements have not given any evidence for chloride entry into the film. Amount of charges necessary to cathodically reduce the film tended to diminish after exposure to chloride or bromide containing solutions. The results suggest a thinning of the passivating film on iron by halides with subsequent pitting.

The effect of illumination on passivity and the initiation of pitting corrosion on pure iron in borate buffer pH 8.4 is studied. It is observed that a monochromatic (325 nm) illumination of the sample leads to a very strong increase in its pitting corrosion resistance-apparent from pitting potential
