为了阐明耐候钢中抗腐蚀合金元素的作用，采用空气氧化法制备了不同Ti（IV）、Cr（III）、Cu（II）和Ni（II）含量的FeSO 4溶液，制备了γ-FeOOH和Fe 3 O 4颗粒。Cr（III）、Cu（II）和Ni（II）的加入降低了γ-FeOOH的结晶度和粒径，而Ti（IV）的加入对γ-FeOOH的结晶度和粒径影响不大。所有的金属离子以类似的方式阻碍Fe 3 O 4的结晶和颗粒生长。并将γ-FeOOH和Fe_3O_4的结果与文献报道的α-和β-FeOOH的结果进行了比较，以了解金属离子对锈形成的综合影响。
To elucidate the role of anti-corroding alloying metals in weathering steels, the γ-FeOOH and Fe3O4particles were prepared by air-oxidation of FeSO4solutions containing different amount of Ti(IV), Cr(III), Cu(II) and Ni(II). The crystallinity and particle size of γ-FeOOH were lowered by adding Cr(III), Cu(II) and Ni(II) but not influenced by Ti(IV). All the metal ions impeded the crystallization and particle growth of Fe3O4in a similar manner. The results on γ-FeOOH and Fe3O4were compared with those on α- and β-FeOOHs previously reported to know the comprehensive effects of metal ions on the formation of rusts.
