The aim of the work is to study the kinetic dependences of deposition and dissolution of alloys that are components of multilayer coatings, oxidation of alcohols and polysaccharides, kinetic characteristics of anode processes on the surface of titanium alloys. Methods: cyclic voltammetry, chronoamperometry, chronopotentiometry, pulse electrolysis, gravimetry, X-ray fluorescence analysis, X-ray phase analysis, optical microscopy, Vickers method for measuring microhardness, flexible cathode method for measuring inner stress. New regularities of deposition and dissolution of Cu-Zn, Sn-Zn, Zn-Ni, Cu-Sn alloys that are components of multilayer coatings were obtained, the increase in microhardness and corrosion resistance of (Zn-Ni)1/(ZnNi)2 and (Cu-Sn)1/(Cu-Sn)2 coatings as compared to the component alloys and the corrosion protection of the electronegative surface by (CuNi)/(Ni-Cu) coating. New dependences of ethanol and glucose oxidation were obtained on a multilayer nickel hydroxide coating for the fuel cells and glucose sensor and hydrogen reduction after surface modification. New methods of voltammetric express analysis of Zn-Ni and Cu-Sn alloy layers are developed, which allow quantitative determination of element and phase composition of alloys in the thickness range from 10 nm to 3500 nm. The conditions of stabilization of the properties of the electrolyte with an increase in 4.3 times of the inter-regeneration period, as compared to the pyrophosphate electrolyte are determined. The mode of formation of porous and porous oxide films is proposed.
