A new approach to the creation of composite wear-resistant coatings is proposed, which consists in realizing the advantages of combining the effect of mechanical nanocrystallization and mechanochemical reactions in the near-surface layers treated with ultrasonic impact treatment (UIT) in chemically active and inert media. This fundamentally distinguishes the proposed technique from the known methods of synthesis of bulk composite materials and provides more effective, compared to heat treatment and standard UIT schemes, surface hardening.

The created scientific bases and regularities of electrochemical formation of ordered nano- and micro-level materials of hemotronics are based on a clear separation of the influence of the charge transport mechanism of the limiting stage of the electrochemical process on the stratification of the structure of the surface oxide and metal phases of the electrode. The structuring of semiconductor phases is governed by the ratio of gradients of the electric field and charge carriers in liquid and solid phases.

Prototypes of new catalysts and photocatalysts based on newly synthesized nanoscale metal oxides obtained, kinetic regularities of redox processes in which they participate in waste water determined. The experimental dependence of the degree of photocatalytic purification in model wastewater and the nature of the pollutant concentration established. Substantiation of technological parameters of the liquid-phase oxidation-reduction processes wastewater from the pollutants of various origins determined.
