摘要	The influence of Cl- concentration in corrosion medium to crevice corrosion of X70 pipeline steel was investigated by wedge-type crevice model. The experimental results show that under natural corrosion condition, as the crevice opening thickness is 0.15 mm and the test periodic is 120 h, with increase of the Cl- concentration (c(Cl-)(m)) in corrosion medium outside the crevice the Cl- concentration (c(Cl-)(c)) in the crevice solution from the opening to the bottom gradually increases, the pH value in the crevice solution and the electrode potential of X70 steel samples from the opening to the bottom in the crevice gradually decrease, which indicated that crevice corrosion tendency of X70 steel increases with increase of the Cl- concentration (c(Cl-)(m)) in corrosion medium outside the crevice.
