Corrosion Study of 80S Steel under the Coexistence of CO<sub>2</sub> and H<sub>2</sub>S
Published 2022-11-01“…The results show that: (1) In the corrosive environment of CO<sub>2</sub> and H<sub>2</sub>S coexistence, temperature is a major factor affecting the corrosion rate of 80S steel, and increase in temperature accelerates the corrosion process. (2) Corrosion rate is also affected by the CO<sub>2</sub> and H<sub>2</sub>S partial pressure ratio; high S content at high temperatures will inhibit the corrosion process, and vice versa for low temperature. (3) With an increase in the temperature, the corrosion potential decreases, corrosion current density increases, and polarization curve gradually moves to the right. (4) The shape of the cathodic branch moves in the X-negative direction by increasing S content, and the cathodic reaction is jointly controlled by activation and diffusion processes, when the temperature is 100 °C, whereas the anodic branch of the polarization curve at a 3% concentration of Na<sub>2</sub>S.9H<sub>2</sub>O changes significantly and a passivation zone appears. (5) The results of the impedance spectra showed that the impedance radius of the metal decreases significantly at increasing temperatures. …”
