Electrochemical passivation of iron alloys and the film characterisation by XPS
Source abstract
Abstract
The initial stages of oxide growth and composition of passive films developed electrochemically on iron alloys viz. AISI 304, 316 and incoloy 800 were studied by X-ray photoelectron spectroscopy. The results showed an enrichment of chromium in the passive films and the thickness of the films were of the same order on all the alloys. The hydroxide species were found to dominate at the oxide solution interface. The air oxidised film showed the presence of both chromium and iron in the oxidised state unlike the electrochemically developed passive film where chromium was found to be the dominant oxidised species.
