Information × Registration Number 0123U102774, ( 0223U004872  ) R & D request Title The modification of the surface of a solid body under the action of plasma and beams of charged particles. Head Beresniev Viacheslav M., Доктор технічних наук Registration Date 05-06-2023 Organization V.N. Karazin Kharkiv National University popup.description1 To expand fundamental knowledge about the conditions of formation and dynamics of a self-sustained beam-plasma discharge in stationary and pulsed systems, physical mechanisms of generation of intense beams of charged particles in plasma. To optimize the processes of coatings formation and their modification, to study the effect of intense beams of charged particles, high-density plasma flows and high-energy radiation on the surface of solid bodies, their structure and operational characteristics. To establish general regularities of structural and phase transformations, as well as physical processes and phenomena that occur during the formation of nanocrystalline layered nitride coatings deposited under non-equilibrium conditions from vacuum-arc plasma. Identify and analyze the peculiarities of the physical and mechanical properties of layered protective nitride coatings of different layer thicknesses. To develop the physical basis for the creation of layered nitride coatings with a predetermined complex of physical, mechanical and chemical properties. Take into account the features of the nitride formation process and the properties of the compounds when choosing the studied systems and alloying elements for multicomponent alloys, as well as for obtaining nitride coatings based on them. To expand existing ideas about the physical mechanisms of formation of structure and properties and analysis of the role of plasma and ion energy in the processes of creating nitride vacuum-arc coatings. popup.nrat_date 2024-12-09 Close
