Документ Structural-phase changes in thin films and surface layers of Ti₄₁.₅Zr₄₁.₅Ni₁₇ alloy, stimulated by radiation-thermal impact of hydrogen plasma(Kharkiv Institute of Physics and Technology, 2019) Malykhin, S. V.; Makhlai, V. A.; Surovitskiy, S. V.; Borisova, S. S.; Herashchenko, S. S.; Kondratenko, V. V.; Kopylets, I. A.; Baturin, A. A.; Terentyev, D.X-ray diffraction and SEM microscopy were used to study structural and phase changes in the surface layers of a Ti₄₁.₅Zr₄₁.₅Ni₁₇ alloy bulk sample (target) and a thin film (deposited by magnetron sputtering of the target) under radiation-thermal action of pulsed hydrogen plasma with a thermal load of 0.6 MJ/m² in QSPA Kh-50 installation. It is established that the irradiation results in the formation of a two-phase state: the icosahedral quasicrystalline phase together with the phase of the 1/1 approximant crystal (W-phase). As a result of isothermal (550°C) annealing, the content of the quasicrystalline phase increases.Документ Features of surface modification of copper-based alloys under powerful plasma exposures(Kharkiv Institute of Physics and Technology, 2018) Byrka, O. V.; Aksenov, N. N.; Chunadra, A.; Fomina, L.; Herashchenko, S. S.; Makhlai, V. A.; Malykhin, S. V.; Sereda, K.; Surovitskiy, S. V.; Garkusha, I. E.Paper presents features of plasma alloying of Cu-based materials with Ti-Cr, Ti-Cr-Ti-Nb, Ti-Cr-Ti-Zr, Ti-Cr-Ti-ZrO coatings in different regimes of the QSPA Kh-50. Targets were made from copper samples covered of multilayer PVD coatings have been deposited within a Bulat-type facility. Prepared targets were irradiated with powerful plasma streams with energy loads achieved 0.6 MJ/m² and the pulse duration of 0.25 ms. Influence of plasma impacts on modification different copper alloys has been analyzed. Mechanisms of modification of thin multilayered coatings mixed with Сu substrate in a liquid phase under the plasma processing are evaluated.
