    Synthesis and functional properties of mixed titanium and cobalt oxides
    (Institute for Single Crystals, 2017) Ved, M. V.; Sakhnenko, N. D.; Karakurkchi, A. V.; Mayba, M. V.; Galak, A. V.
    Peculiarities of plasma-electrolytic oxidation of the aluminum alloys in diphosphate electrolytes are discussed. It is shown that PEO parameters depend on the composition and concentration of the components of the working solutions. The mechanism of cobalt oxides incorporation into the composition of surface layers is proposed. It has been established that the oxidation of titanium in citrate-diphosphate electrolytes promotes the formation of mixed oxide layers TiOx·CoOy. The obtained mixed oxide systems have a developed microporous globular-toroidal surface and are characterized by a complex of enhanced functional properties - corrosion and abrasion resistance, catalytic activity in the carbon (II) oxide conversion reaction.

    Functional mixed cobalt and aluminum oxide coatings for environmental safety
    (Institute for Single Crystals, 2017) Ved, M. V.; Sakhnenko, N. D.; Karakurkchi, A. V.; Myrna, T. Yu.
    Principles of plasma-electrolytic oxidation of the aluminum alloys in diphosphate electrolytes are discussed. It has been established that a variation in concentration of the electrolyte components and electrolysis parameters (current density and treatment time) provides the formation of oxide coatings consisting of the basic matrix materials and the cobalt oxides of different composition and morphology that are expected to affect their functional properties. Mixed oxide coatings formed in a plasma-electrolytic mode characterized by microglobular structure with reducing the conglomerate size have an increased abrasion and wear resistance and an intense catalytic activity. Thus, there is a prospect of using such coatings in the process of burning fuel in internal combustion engines and reduce the toxicity of emissions improving fuel efficiency and environmental performance of engines and in the industrial systems of catalytic purification of exhaust gases of industrial plants and power system facilities.
