Abstract  

The electrochemical behavior of MS X65 pipeline steel in H2S containing medium by different stress ratios (R) was investigated via electrochemical test techniques such as dynamic potential polarization, linear polarization, and electrochemical impedance. The results indicated that electrochemical kinetic parameters such as free-corrosion current density Icorr, electron transfer resistance Rct, and linear polarization resistance Rp all increase or decrease first with the increase of the cyclic stress frequency, and then stabilized by a critical cyclic stress frequency. The critical frequency increased from 0.25 Hz for R=0.4 to 1 Hz for R=0.85, which would be related to the interactive influence of different stress ratios and cyclic stress frequencies on the electrochemically active reaction sites on the electrode surface and the diffusion rate of cathode reactants.
Key words:  MS X65 pipeline steel      cyclic stress      critical cyclic stress frequency      stress ratio
