Evaluation of microstructural and environmental effects on the hydrogen uptake and desorption in high-strength carbon steels: A thermal desorption spectroscopy study
Karimi, Shabnam; Taji, Iman; Palencsar, Simona; Dugstad, Arne; Hajilou, Tarlan; Barnoush, Afrooz; Verbeken, Kim; Johnsen, Roy; Depover, Tom (Peer reviewed; Journal article, 2023)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. ... -
Hydrogen uptake during active CO2-H2S corrosion of carbon steel wires in simulated annulus fluid
Skilbred, Ellen Synnøve; Palencsar, Simona; Dugstad, Arne; Johnsen, Roy (Peer reviewed; Journal article, 2022)The hydrogen uptake of five carbon steel wires exposed to a corrosive CO2/H2S environment where protective film formation was not favorable was measured. The hydrogen uptakes decreased with the accumulation of retained ... -
Role of cementite morphology on corrosion layer formation of high-strength carbon steels in sweet and sour environments
Karimi, Shabnam; Taji, Iman; Hajilou, Tarlan; Palencsar, Simona; Dugstad, Arne; Barnoush, Afrooz; Verbeken, Kim; Depover, Tom; Johnsen, Roy (Peer reviewed; Journal article, 2023)The effect of cementite morphology on the corrosion layer formation of four high-strength carbon steels was studied in an aqueous solution containing CO2 and CO2/H2S. The linear polarization resistance and weight loss data ...
