Abstract

The effect of pH value on the electrochemical corrosion and stress corrosion of X100 pipeline steel in CO₃^2-/HCO₃^- containing solutions were studied by means of measurements of potentiodynamic polarization curve, AC impedance spectrum and Mott-Schottky curve, as well as slow strain rate tensile test. The results showed that with the increasing pH value, the thickness and compactness of the formed passive film and the pitting potential of X100 pipeline steel increase, while its SCC sensitivity reduces to certain extent.

Key words: X100 pipeline steel stress corrosion pH value surface
