abstract = "A rectangle crevice assembly was used to investigate the effects of cathodic protection (CP) potential, bubbling CO 2 and surface condition on the crevice corrosion of X70 steel under disbonded coating. Results show that the solution within the crevice becomes more alkaline due to the reduction of dissolved oxygen. As a result, the potential of the steel reaches the protected potential range and thus the protection distance becomes longer when the applied CP potential is more negative. The IR drop mainly occurs in the vicinity of the opening. However, the introduction of CO 2 into the solution prevents the formation of an alkaline environment and forms a nearly neutral SCC potential-pH environment in the crevice. In addition, it is also found that the pre-corrosion product layer significantly decreases the polarization rate in the crevice.",
