The Formation of Sulfide Scales on Carbon Steel in Saturated H2S حسب Alqahtani, Noora

"…The electrochemical reaction commonly contains three stages: first, the reactant transported from the solution (bulk) to the metal surface; then the transfer of the charge reaction on the surface, followed by the reaction product transported away from the iron surface to the bulk solution or the formation and development of the corrosion product which then can decrease the corrosion rate. Development of a robust corrosion model to predict the corrosion process in H2S these requires a mechanistic understanding of all these elements. …"
