Full textThesis for granting the Degree of Doctor of Technical sciences in speciality 05.17.03 – Technical Electrochemistry. – National Technical University "Kharkiv Politechnical Institute", 2019. The dissertation is devoted to the development of scientific principles of electro-chemical processes in the technology of functional molybdenum and tungsten-containing coatings. The hypothesis of the possibility of controlling the nature of electrochemical processes, with the participation of molybdenum (VI) ions and tungsten (VI) associated with the achievements in the study of the state of the forms of their ions in aqueous solutions is formed and experimentally proved. The influence of the nature of molybdenum oxyanion on the kinetics of cathode processes in complex electrolytes within a wide range of pH: ammonium pyrophosphate (pH> 7) and ammonia-trilonate (pH <7) is proved. The understanding of the controlled influence with the form of molybdenum oxoanions on the polarization of the cathode process for the change of the limiting stage is developed. It has been confirmed that the cathode processes in the precipitation of the Co-Mo alloy include the restoration of molybdenum oxoanions due to not only the electrochemical stage but with the participation of oxi-dation-reduction reactions in which the reduction products are those of combined electrode reactions - cobalt and adsorbed hydrogen. The influence of the electrolytes composition and electrolysis parameters on functional properties of coatings (corrosion resistance, microhardness, catalytic activity in the reaction of CO conversion and electrochemical hydrogen release) is determined. The compositions of electrolytes are treated experimentally to create conversion coatings on silver surfaces and D16 alloy. It is proved that the change of pH in the electrolyte of the anode-oxide coating on the D16 alloy changes the form of oxoanions and increases the corrosion re-sistance of the system. It is established that with the thiosulfate concentration in-crease, the silver potential moves toward negative values due to the formation of [Ag(S2O3)n](2n+1)-, which allows the process of oxidation-reduction reactions involv-ing tungsten and silver polyanions. The use of a silver surface tester on the basis of tungstate is 2 times more efficient than a chromate-based passivator. A catalyst is obtained for the Ti|TiOx·WOp·CeOy·ZrOz·CuOn composition, which is characterized by high conversion activity of CO (up to 95% at 420 °C). Anodic oxide coatings on OT4-0 containing molybdenum compounds exhibit suppressed conductivity and heat resistance of the anode layer. The oxide coatings formed from the molybdenum-containing electrolyte on a steel 08Х18Н10 have an electrical resistance of 2.6·1010…3.6·1010 Ω. The effectiveness of scientific study is proved by the positive results of laboratory and industrial testing and implementation.

Full textDissertation for the Degree of the Doctor of Engineering Sciences in the Specialty of 05.17.03 – Technical Electrochemistry. – National Technical University "Kharkіv Polytechnic Institute", Kharkіv, 2018. This doctoral thesis is devoted to the development of scientific basics for electrochemical technologies used for the application of coatings consisting of ternary iron and cobalt alloys combined with molybdenum and tungsten of improved functionality. The hypothesis as for the competitive reduction of iron ternary metals with refractory components preconditioned by the mutual interaction of thermal-&-dynamic and crystal-&-chemical characteristics of the alloy-forming metals and the kinetic parameters of cathode process and it was proved experimentally. The kinetic regularities of the co-reduction in Fe³⁺ ‒ MoO₄²⁻ ‒ WO₄²⁻ ‒ Cit³⁻, Fe³⁺ ‒ Со²+ ‒ WO₄²⁻ (MoO₄²⁻) ‒ Cit³⁻ systems have been defined and the mechanism of deposition of ternary Fe-Mo-W, Fe-Co-W (Mo) alloys has been substantiated. The influence of composition of electrolytes and modes of electrolysis on elemental, phase composition and surface morphology of the obtained coatings has been deter-mined. The possibility of controlling the composition and morphology of multicomponent coatings on the basis of iron and cobalt by varying the composition of the electrolyte (the ratio of component concentrations, the ratio of ligand and complexing agent), and by used of galvanostatic and pulsed electrolysis regimes with a ranging of current density 2.5 ‒ 6.5 A/dm², and durations pulse/pause 5 ‒ 10 / 5 ‒ 20 ms, has been proved. The electrolytes and the deposition modes were developed that provide the deposition of Fe-Co-W coatings with the Co content of 32 to 47 аt. %, and W of 5 to 13 аt. %, and Fe-Mo-W coatings with the tungsten content of 5 to 11 at. %, and the molybdenum contents of 26 to 32 at. %, and the Fe-Сo-Мо coatings with the Co content ranging from 26 to 48 at. %, and Mo content ranging from 15 to 31 at. %, and the current efficiency ranging from 58 to 82 %. The variation schemes of electrochemical processes were suggested and these allow for the deposition of Fe-Mo-W and Fe-Co-W(Мо) coatings depending on their practical application. The perspective directions of the application of the obtained materials according to the results of experimental researches and tests of functional properties in model environments and technological conditions are determined.

Full textThesis for granting the Degree of Candidate of Technical sciences in specialty 05.17.03 – Technical Electrochemistry. – National Technical University "Kharkiv Polytechnic Institute", Kharkiv, 2015. The thesis work is devoted to the improvement of the sulfate production technology of the pigment TiO₂ via renewal of ions in the aqua of Fe³⁺ and TiO²⁺ not Fe, Al, but electrochemically, what excludes the chromophor accumulation in fluid converter mouth, thereby guarantees the end products high quality. However currently the overpressure of hydrogen separation and delay discharge theories are not general, that is why the search of cathode materials with the smallest hydrogen overpressure was performed. The solution was achieved via analysis of the double electric layer (DEL), where renewal of Fe³⁺ and TiO²⁺ occurs involving H⁺, Н⁰, Н¯, Н, H₂⁺ joins through relay mechanism. It is determined that ndm materials and their alloys, which have law electrical resistivity and are apt to hydrogen accumulation, they are stainless steel and niobium, are the best materials. Lorentz force is used during development of electrolyzer for convection diffusion increasing in the Ti₂(SO₄)₃ reductor synthesis. New optical Ti³⁺ control methods and creation of electrolysis computer control complex or ACS are offered during applying of synthesis on an automatic basis.

Full textThesis for the degree of candidate of technical sciences in specialty 05.17.03 – technical electrochemistry. – National Technical University "Kharkov Polytechnic Institute", Kharkiv, 2018. The thesis is devoted to the improvement of the technological process of applying copper coatings to products made of alloys of iron and aluminum, which are intended for electrical purposes. The kinetics and mechanism of the reduction of the copper hydroxotartrate complex are studied. It is found that the cathodic process includes delayed stage of electron transfer and chemical dissociation stage of the complex ion. The composition of the electrolyte for copper deposition has been developed, which ensures the deposition of coatings with good adhesion to the electronegative base. The resulting solution is environmentally safe and stable for long-term use. The effect of electrolysis parameters on the morphology and quality of the coatings was studied. In order to improve the adhesion of the copper deposit to parts made of aluminum alloys, it is necessary to create an oxide film having a developed porous surface, which is specified by the conditions of its formation. The corrosion and electrical characteristics of the oxides formed are revealed. It is determined that the addition of the fluoride ion (as activating impurity to the electrolyte for copper plating) promotes a more even distribution of the metal over the surface of the alloys.
