... industry. However, H 2 S corrosion mechanisms, specifically at high partial pressures of H 2 S (pH 2 S), have not been extensively studied because of experimental difficulties and associated safety issues. The current study was conducted under well-controlled conditions at pH 2 S of 0.05 and 0.096 MPa...
