Popis: The self-consistent field Xα-SW cluster method was used for theoretical interpretation of the electronic structure of the intercrystalline phase in nanostructured Cu-Fe-O alloys produced by copper-steel sliding. The calculations of electronic structure were based on the model of the intercrystalline Cu-Fe-O phase as an aggregate of nFe2nO clusters arranged in a Cu host. The final calculations explain the absence of charge transfer between metal and oxygen atoms in the alloys studied as a consequence of covalent FeO bond formation in small nFe2nO clusters, and not an ionic one, as in bulk oxides.
