- Abstract
- In order to predict and understand general and localized corrosion attacks on carbon steels in sour service, fundamental understanding of the growth and breakdown mechanisms of iron sulfides is required. Based on the concept of “Conservative Ensembles”, a model for the solid-state growth mechanism of sulfur-deficient iron sulfide has been developed. The model enables numerical simulations of iron sulfide growth limited by multicomponent transport through the FeS layer using the phenomenological formalism of linear irreversible thermodynamics. ©NACE International.
