The Influence of the pH Value and the Cation Composition of Dispersion Medium on the Formation of Iron-Oxygen Structures on Steel Surface
The peculiarities of the formation of iron-oxygen structures on steel surface due to its contact with aqueous dispersion medium within a wide range of pH values and in presence of cobalt and silver have been studied by X-ray diffraction in situ. It has been shown that well crystallized cobalt- and i...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The peculiarities of the formation of iron-oxygen structures on steel surface due to its contact with aqueous dispersion medium within a wide range of pH values and in presence of cobalt and silver have been studied by X-ray diffraction in situ. It has been shown that well crystallized cobalt- and ironcontaining spinel ferrites are formed at neutral pH value of aqueous medium. The contact of steel surface with alkaline medium results in formation of weakly crystallized iron oxyhydroxides. The structure of lepidocrocite is formed on steel surface due to its contact with acid dispersion medium in absence of metal ions such as cobalt and silver. |
