Abstract

The data on investigation of oxide-ceramic coating formed by microarc oxidation of porous samples from aluminum alloys of different chemical composition (AK15, AMg6, D16) are presented. The microstructure of the obtained composites, pore size distribution, macrostructure of the surface of porous aluminum samples before and after microarc oxidation, phase and elemental composition were studied. It is shown that microarc oxidation leads to the formation of a composite coating consisting of various forms of aluminum oxide (α-, γ-Al2O3) and mullite 3Al2O3·2SiO2. It is noted that the obtained oxide compounds of aluminum and silicon can serve as the basis of sorbents for immobilization of chemical and biological substances with different molecular weights, as well as cells of microorganisms, in particular Escherichia coli.
