摘要/Abstract

摘要： 应用电化学动电位再活化法(EPR法)评价不锈钢复合板和低铬铁素体不锈钢的晶间腐蚀敏感性. 结果表明，以电化学动电位再活化法测得的反向扫描与正向扫描电流最大值之比（ir / ia）评价堆焊不锈钢复合板00Cr17Ni14Mo2/20R复层晶间敏感性与传统H2SO4-CuSO4-Cu法测定的结果吻合甚好；评价爆炸复合板复层06Cr13R低铬铁素体不锈钢晶间腐蚀敏感性与草酸浸蚀法测定的也一致. 说明该法可以成功用于定量、定性地评价不锈钢复合板和低铬铁素体不锈钢的晶间腐蚀敏感性.

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.

Key words: EPR method, intergranular corrosion, stainless steel composite plate, low-Cr ferritic stainless steel
