%X We have verified through an electrochemical technique (capacity, impedance
and photo-electro- chemical measurement) and also through an analytic technique
of auger spectrometry that passive films formed on inconels 600 and 690 are comprised of two
layers. This has led us to establish precise links between the chemical composition
of passive films formed on inconels and their electrochemical properties. The results
obtained at different frequencies show the existence of two areas. The passive oxide
formed on alloy 600 is richer in iron oxide than the one formed on alloy 690.
