Abstract
The susceptibility to intergranular corrosion of overlay welding stainless steel composite plate (00Cr17Ni14Mo2) and low-Cr ferritic stainless steel (06Cr13R) was studied by electrochemical potentiokinetic reactivation (EPR) method. The results indicated that the ratio of the maximum current Ir/Ia generated by the reactivation EPR scan to that of the anodic scan is appropriate for evaluating the intergranular corrosion of 00Cr17Ni14Mo2, which is consistent with the H2SO4-CuSO4-Cu method, and also appropriate for evaluating the intergranular corrosion of 06Cr13R, which is consistent with the oxalic acid test method. It shows that the EPR method can be applied to qualitatively and quantitatively evaluate the susceptibility to intergranular corrosion of stainless steel composite plate and low-Cr ferritic stainless steel.
