Abstract

The hydrogen uptake in three high-strength carbon steels is studied after exposure to three different environments: an aqueous solution with CO₂ bubbling, CO₂/H₂S bubbling, and cathodic charging without external gassing. The hydrogen uptake is substantially higher in CO₂/H₂S environment compared to CO₂ environment for all materials. The lamellar cementite morphology absorbs higher hydrogen than the material with spheroidite microstructure with similar carbon content. The corrosion layer formed on the steels in CO₂ environment strongly affects the hydrogen effusion and the thermal desorption spectroscopy spectrum in all materials, while the corrosion layer formed in CO₂/H₂S environment does not show this effect.
