| الملخص: | <p dir="ltr">The hydrogen uptake in three high-strength carbon steels is studied after exposure to three different environments: an aqueous solution with CO<sub>2</sub> bubbling, CO<sub>2</sub>/H<sub>2</sub>S bubbling, and cathodic charging without external gassing. The hydrogen uptake is substantially higher in CO<sub>2</sub>/H<sub>2</sub>S environment compared to CO<sub>2 </sub>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 CO<sub>2</sub> environment strongly affects the hydrogen effusion and the thermal desorption spectroscopy spectrum in all materials, while the corrosion layer formed in CO<sub>2</sub>/H<sub>2</sub>S environment does not show this effect.</p><h2>Other Information</h2><p dir="ltr">Published in: Corrosion Science<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.corsci.2023.111210" target="_blank">https://dx.doi.org/10.1016/j.corsci.2023.111210</a></p> |
