Paton Electric Welding Institute (PWI) popup.description1 The aim of the project is to develop the scientific foundations for energy-saving technologies to produce high-quality joints of dissimilar materials in the solid phase using methods of concentrated pulsed magnetic field (PMW) exposure for special-purpose products. It also aims to obtain new functional nanomaterials through localized glow discharge in a dynamic vacuum for the production and preparation of widely used antiseptic agents, create multilayered metal sheets through explosion welding with increased economic efficiency and productivity, and develop biocompatible tantalum coatings with the necessary functional characteristics, along with the scientific basis for applying such coatings using microplasma spraying (MPS) on endoprosthesis surfaces. The project plans to: • Conduct comprehensive theoretical and experimental studies on the impact of the design and materials of inductor tools on the energy efficiency parameters of the magnetic-impulse welding process; • Perform comprehensive theoretical and experimental studies on the influence of energy parameters of localized glow discharge in a dynamic vacuum within a quasi-closed volume to control the size distribution of nanoparticles; • Conduct analytical and experimental studies on the influence of the characteristics (layer height, density, load factor) of the inert layer placed over the explosive material (hereinafter referred to as the tamping) on the modes of explosion welding (detonation velocity of the explosive material, collision speed of welded plates, angle of rotation of the flying plate); • Conduct comprehensive theoretical and experimental studies to establish the influence of MPS parameters on the dispersion process of tantalum wire and the properties of the formed biocompatible tantalum coatings. popup.nrat_date 2025-01-29 Close
