Abstract : Studies are reported on the dissolution of protective films and on the transient dissolution behavior of Fe-Cr-Ni alloys. The properties of passive films were studied using an optical ellipsometer together with simultaneous coulometric measurements. It was possible to measure film growth and dissolution processes simultaneously. The dissolution of bulk oxides was also studied in acid and caustic solutions to assess effects of anions and cations. Finally, transient dissolution and repassivation was studied using transiently strained electrodes held at constant potential.
