The paper is devoted to studying the possibility of application of tributylamine (TBA) as volatile inhibitor of hydrogen sulfide corrosion (HSC) of steels. The influence of С(H2S), pH and temperatures on TBA protective action is studied as well. Amine adsorption on steel surface modified by sulfide has been investigated and TBA impact on its composition and structure has been reviewed using a number of electrochemical methods, ellipsometry and XPS. The contributions of corrosion products and inhibitor films to the total protective effect have been estimated on the basis of the developed method.
