Mayba M. Functional coatings on titanium alloys

The subject of this research is electrochemical and thermochemical process during the oxide coatings formation on titanium alloys. The research objective is the development of catalytic, protective, dielectric and antifriction coatings on titanium alloys technology based on the hypothesis on the mixed oxide coatings formation in high-energy fields. Methods of examination are the direct voltammetry, X-ray fluorescence and X-ray diffraction technique, optical and scanning microscopy, impedance spectroscopy, Calotte method. As the result of theoretical and bottom line it has been established the microarc synthesis regularities of functional coatings on titanium alloys; it has been proposed the scheme of transformations during the manganese-containing coatings formation in high-energy fields, the electrolytes and modes for the oxide coatings range with dopants obtaining. The novelty is the catalytic, antifriction, protective, insulating mixed oxide coatings on titanium alloys one-step by the electrochemical and thermochemical reactions during the microarc oxidation. The realization degree consist of the corrosion stability and insulating properties of oxide coatings tests in "INGIR" Ltd., Kharkiv, and mixed oxide systems catalytic activity on the ACTS and ECM department in NTU "KhPI". The branches of this research application are the chemical and industries, the technical process of electrochemical production, Research Studies Institutes and а training process.
