Influence of NaCl on Corrosion Behavior of API P105 Steel in CO2 Saturated Solution

    Graphical Abstract
    • Abstract
  • The effect of NaCJ on the corrosion behavior of API P105 steel in the CO2-saturated solution was studied by electrochemical impedance spectrum(EIS) and polarization measurement. The results showed the increase of NaCl concentration decreased the the corrosion rate of the steel, which could be attribulted the decrease of hydroxide ion concentration and the dissolution of CO2, and the adsorption of Cl- obeyed the Temkin isotherm.
