| Abstract: | For simulation of atmospheric corrosion of steels, artificial steel rust particles were prepared in acidic aqueous solutions containing FeCl3, Fe(NO3)3 and Fe2(SO4)3. A single phase α-FeOOH was formed in only Fe(NO3)3 system. The β-FeOOH was formed by added Cl? in FeCl3–Fe(NO3)3 system. Adding SO42? in Fe(NO3)3, FeCl3 and a mixture of FeCl3–Fe(NO3)3 solutions turned the products following as α- or β-FeOOH → Schwertmannite (Fe8O8(OH)6(SO4)·nH2O). Further, increasing the added SO42? suppressed the formation of steel rust particles. Accordingly, the influence of anions on the formation of steel rust particles was to be suggested in order of SO42? ? Cl? > NO3?. |
