Corrosion study of the passive film of amorphous Fe-Cr-Ni-(Si, P, B) alloys
Keywords:Amorphous alloys, Corrosion, EIS, Photoemission, Passive layer
Amorphous Fe62Cr10Ni8X20 (X = P, B, Si) alloys in 0.01M HCl solution have been investigated by means of standard electrochemical measurements in order to evaluate their corrosion resistance. The study reveals that the best corrosion behaviour is given by the Si containing amorphous alloy. X-ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy (AJES) have been employed to study the composition of the passive layers, formed on the surface of the different amorphous alloys. The results on Fe62Cr10Ni8X20 show that a protective passive film, mainly consisting of oxidized chromium, greatly enhances its corrosion resistance.
