Ved M. Electrochemical synthesis of functional coatings by metal d4-9 alloys and mixed oxides for ecotechnologies

Electrochemical synthesis of functional coatings by metal d4-9 alloys and mixed oxides for ecotechnology. Regular trends of catalytic coatings by transient metals alloys and mixed oxides development. Research technique: complex of physical-chemical and electrochemical methods. The correlation between metals and synergetic (additive) alloys catalytic activity and fundamental characteristics is established. The metal finishing technique for substrate surface decrease is proposed. Theoretic based electrolytes composition and synthesis regimes are designed for alloy coatings of various composition formation. Firstly, the hypothesis on aluminum alloys corrosion resistance decrease after microarc oxidizing in diphosphate containing solutions is approved. The microarc technologies of mixed oxides on aluminum alloys are developed. The optimal composition of coatings by alloys Ni-W, Co-W, Ni-Cu, Ni-Pd and mixed oxides Al2O3, MnxOy; Al2O3, CoxOy similar in corrosion resistance and catalytic activity for platinum are established. The coatings are introduced in catalytic purification device of rubbish-burning plant. Sphere of application: hydrogen electrochemical synthesis, gaseous wastes and sewages purification.
