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.

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.
