Growth and Stability of Passive Films

open access: yesCorrosion Science, 2002
Abstract This paper will consider the growth and breakdown of passive oxide films on metals and alloys. Emphasis is placed on the use of surface-analytical techniques, particularly secondary ion mass spectrometry (SIMS) to characterize oxides formed on Fe and Fe-Cr alloys in18O-containing solutions, and to determine the oxide's stability to ...
