Abstract:
The processes of plasma-electrolytic formation of heteroxide coatings on titanium alloys for the photocatalytic disintegration of natural and technogenic toxicants are studied. Synthesis of coatings was carried out from aqueous diphosphate solutions in the galvanostatic mode. For a quantitative description of photocatalytic reactions, reaction rate constants were calculated from the linearized dependences lnCt/C0, where Ct is the current concentration of the azodye and C0 is the initial concentration of the reactant. The surface morphology of the coatings was studied by atomic force microscopy

Abstract:
CO-, W-, MO- and Zn-containing hetero-oxide nanostructured coatings on titanium and its alloys formed by plasma-electrolyte oxidation in galvanostatic mode from alkaline electrolytes were investigated. The morphology of the surface of the formed coatings was studied by scanning microscopy on the Zeiss Evo 40XVP microscope. The phase composition of the obtained coatings was determined on the X-ray diffractometer Drone-2.

Abstract:
The results of a study of the influence of the parameters of plasma-electrolytic oxidation in diphosphate electrolyte solutions of metal platforms made of titanium alloys, as the basis for the formation of heterooxide coatings with photocatalytic activity, on the level of their functional properties are presented. It has been established that heterooxide coatings obtained in PEO modes on titanium alloy platforms, in which zinc and tungsten compounds were incorporated as dopants, demonstrate photocatalytic activity in the processes of azo dye degradation under UV irradiation.

Based on the review of the peculiarities of the photocatalytic processes, the peculiarities of the catalytic action of oxide systems based on titanium dioxide are determined. It is shown that TiO2 is one of the most chemically and thermally stable and non-toxic inorganic oxides of semiconductors, whose photocatalytic activity is manifested by irradiation with ultraviolet part of the spectrum (λ 320–400 nm) and allows the oxidation of a significant amount of toxic agents to water and carbon dioxide.

The current problems of today fully include various aspects of the creation of functional materials for various purposes. When creating such materials, economic and environmental components, resource availability and energy intensity of production, as well as the intended purpose of the created products must be taken into account. Largely, the emphasis has now shifted towards research, the results of which should meet the needs of the defense sector, contribute to ensuring the country's energy independence and solve other priority tasks. One of these aspects is improving the energy supply of i
