Abatraet-The passivation of the amorphous alloys Fe,Cr,,X,,C,(X = P, B) was studied combining X-ray photoelectron spectroscopy (XPS) surface analysis and electrochemical measurements. After removing the native (iron oxide) films by mechanical polishing, the alloys form a thin (2 nm), non-protective
The growth kinetics of passive films on Fe, Fe-10 Ni, Fe10 Cr, Fe-10 Ni-10 Cr have been determin ed in pH 8.4 borate buffer solution at 25°C using ellipsometer and coulometric techniques. Films found on the alloys were progressively thinner as the alloy concentration was increased. The correlations
