Abstract
The corrosion products of iron formed on steel surfaces by the immersion of steels in solutions containing chloride, sulfate, and nitrate ions, and in phosphating solutions were analyzed by CEMS and X-ray diffractometry. Positive identification of γ-FeOOH in 0.5M NaCl solutions, γ-FeOOH and Fe (OH)2 in 0.25M Na2SO4 solutions, and γ-FeOOH and Fe3O4 in 0.5M NaNO3 solutions was achieved. Amorphous paramagnetic Fe (III) compound, (Mn, Fe)5H2 (PO4)4 4H2O, and Zn2Fe(PO4)24H2O were mainly produced on the surfaces by the immersion in the iron phosphating, man ganese phosphating, and zinc phosphating solutions, respectively.
