Corrosion behaviour of Fe-9Cr steels in O$_2$ and CO$_2$ containing media thick or thin oxide scale ?

Abstract : In order to better understand the corrosion behaviour of 9Cr steel in CO$_2$ rich gas phase environments and the possible effect of O2 molecules on the corrosion scale formation, a Gas Phase Analysis technique (GPA) was developed and used at CEA. This innovative device dedicated to the study of gas-solid interaction uses labelled gas molecules, mass spectrometer and pressure gaugesfor analysing the evolution of the gas phase composition. The use of this device combined to the analyses of the corrosion product by multiple techniques such as Raman spectroscopy, SIMS, XPS, SEM and TEM was very powerful to propose an entire story of the steel-gas interaction in CO$_2$ and O$_2$ rich environments.
