Objective - on the basis of experimental and rheological processes in the surface contact interaction, fatigue processes, stress corrosion cracking to develop scientific foundations and methods of metals long-term strength improvement based on the implementation of protective substructural phenomena of dissipative nature. Methods of investigation: microdeformations, fretting wear , method of resonant flexural vibrations , method of indenter continuous indentation. Equipment: installation МФК -1, device Talyscan, installations for measuring of metals internal friction, microplasticity, for testing of corrosion, cracking, pulsator MИР -8, УРМ -2000. Theoretical and practical results: the factors that control fretting fatigue are obtained; the changes of steel microplasticity under external factors are established; the influence of fretting corrosion on the steel stress corrosion cracking manifestation is discovered; rheological approaches to metals long-term strength on the basis of material relaxation ability manifestation are revealed. As a result of the project fulfilment, conducting a series of theoretical and experimental researches the rheological principles of metals long-term strength increase under conditions of dynamic contact of conjugated surfaces are established. Fretting fatigue strength increases by 10 % with copper plated steel 40ХНМА , 8% with anoding alloy Д16T , 7 % for phosphating steel 40ХНMA . Blast rate processing increases limited rate of endurance for steels 30ХГСА and 40ХНMA twice and fretting fatigue durability for steel 45 - 7 times, for steels 30ХГСА and 40ХНMA - 15 times . The obtained scientific and practical results can be used in the wide range of institutions and enterprises of machine-building industry and transport wich deali with the questions of tribological conjugations design and manufacturing of parts for them Product Description popup.authors Білик Юрій Мирославович Декалюк Дмитро Юрійович Калда Галина Станіславівна Косткевич Едуард Едуардович Курской Володимир Сергійович Мартинюк Андрій Віталійович Олександренко Віктор Петрович Островський Станіслав Вікторович Паламар Андрій Миколайович Поліщук Володимир Юрійович Соколан Юлія Володимирівна Шевеля Валерій Васильович popup.nrat_date 2020-04-02 Close
