Abstract The corrosion behaviour of iron and steel in aerated aqueous 0.5 M Na 2 SO 4 solutions in the range 7 ≤ pH ≤ 9 was studied on rotating disc electrodes. The polarization curves measured cyclic voltammetrically or under steady‐state potentiostatic conditions show a membrane inhibition effect caused by the time‐dependent formation of three‐dimensional porous oxide layers on the electrode surface. In presence of the inhibitors hexane (1, 6) biphosphonic acid, sodium‐dihydrogenphosphate, Preventol VP OC 2003 and Aktiphos the inhibition effect is markedly enhanced leading to more homogeneous and compact protecting layers.
