| Abstract: | Mild steel (0.24wt% C) can be passivated in triaxial composite flooding solution containing 1.2% NaCl 0.6% petroleum sulfonate 0.12% polyacrylamide(wt%). The composition and structure of passive film formed on the steel were investigated by XPS. The results showed that the passive film was composed of Fe3O4, FeOOH, Fe2O3 and Fe(OH)2, and its thickness was about 7nm. The valence of elemental iron varied at different depth of the passive film. At the outer surface of the passive film, the valence of iron was 3, and at the interface near the matrix, 3 and 2 iron were detected. |
