## 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 t
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
The temperature dependence of anodic oxide growth on passive iron under steady-state galvonostatic conditions has been studied in the temperature range 1440Β°C. The activation energy of the ionic conduction process in y-FesOs is 1.39 eV. The temperature dependence of the field coefficient is linear b
