  • Modification and alloying effects in Eurofer steel under powerful pulsed plasma impacts 
    Byrka, O.V.; Herashchenko, S.S.; Makhlai, V.A.; Aksenov, N.N.; Garkusha, I.E.; Marchenko, H.K.; Chunadra, А.G.; Sereda, К.N.; Malykhin, S.V.; Surovitskiy, S.V. (Вопросы атомной науки и техники, 2021)
    Experimental studies of surface modification of Eurofer samples have been performed with a quasi-stationary plasma accelerator QSPA Kh-50. The heat load on the surface was near the tungsten melting threshold (i.e. about ...
  • Plasma-surface interaction and mechanisms of dust production in ITER ELM simulation experiments with QSPA Kh-50 
    Makhlaj, V.A.; Garkusha, I.E.; Aksenov, N.N.; Byrka, O.V.; Landman, I.; Lebedev, S.I.; Shevchuk, P.B. (Вопросы атомной науки и техники, 2012)
    Experimental simulations of ITER transient events with relevant surface heat load parameters (energy density and the pulse duration) were carried out with a quasi-stationary plasma accelerator QSPA Kh-50. The several ...
  • Structure evolution of tungsten coatings exposed to plasma flows under ITER ELM relevant conditions 
    Malykhin, S.V.; Surovitskiy, S.V.; Makhlaj, V.A.; Aksenov, N.N.; Byrka, O.V.; Borisova, S.S.; Herashchenko, S.S.; Reshetnyak, V.V. (Вопросы атомной науки и техники, 2017)
    Structure, substructure and stress parameters both on the surface and distributed by depth in the tungsten/steel coatings exposed to high energy hydrogen plasma fluxes were studied by X-ray diffraction methods. The hydrogen ...
  • Surface modification and droplet formation under exposures of tungsten coatings with ELM-like transient loads 
    Byrka, O.V.; Aksenov, N.N.; Herashchenko, S.S.; Makhlaj, V.A.; Taran, V.S.; Timoshenko, O.I. (Вопросы атомной науки и техники, 2017)
    Features of surface modification of tungsten coatings after repetitive irradiation with QSPA Kh-50 plasma pulses are presented. Cracking, development of tungsten surface morphology and emission of droplets are studied. ...
  • The microrelief studies of stainless steel mirrors sputtered with Ar⁺ ions of different energy 
    Bondarenko, V.N.; Konovalov, V.G.; Solodovchenko, S.I.; Shtan′, A.F.; Ryzhkov, I.V.; Voitsenya, V.S.; Lytvyn, P.M.; Byrka, O.V.; Skorik, O.A. (Вопросы атомной науки и техники, 2018)
    Four stainless steel mirror specimens were sputtered to an identical mean thickness of the eroded layer 2 μm with Ar⁺ ions. Each specimen was exposed to ions with one kinetic energy from the followings: 300, 600, 1000, ...
  • Сharacterization of ARC-PVD ZrN nanostructured coatings by using the fractals theory 
    Romaniuk, S.P.; Volchuk, V.M.; Taran, A.V.; Nowakowska-Langier, K.; Byrka, O.V. (Problems of Atomic Science and Technology, 2022)
    Nanostructured ZrN coatings for hardening of a thin-walled cutting tools operating under cyclic loads conditions have been obtained and investigated. The structure and mechanical properties of nanocoatings have been examined. ...
