  • Deposition of TiN-based coatings using vacuum arc plasma in increased negative substrate bias voltage 
    Kuprin, A.S.; Leonov, S.A.; Ovcharenko, V.D.; Reshetnyak, E.N.; Belous, V.A.; Vasilenko, R.L.; Tolmachova, G.N.; Kovalenko, V.I.; Klimenko, I.O. (Вопросы атомной науки и техники, 2019)
    The paper presents the results of the study on the influence of a high substrate bias voltage from 300 up to 1300 V on the titanium nitride coating deposition under nitrogen pressure of 2 Pa. The deposition rate, phase and ...
  • Erosion of Co-Cr-W alloy and coating on its basis under the action of cavitation 
    Kovalenko, V.I.; Klimenko, A.A.; Martynenko, L.I.; Marinin, V.G. (Вопросы атомной науки и техники, 2019)
    The average destruction rates (Vs) were measured under the action of cavitation on a pre-production model from the alloy of Co-Cr-W on chemical composition near to the stellite No.6, its initial components and the coating ...
  • Influence of vacuum activated diffusion chroming on mechanical properties of the surface of steel 25X1MF 
    Rudenkyi, S.G.; Zmij, V.I.; Kartzev, N.F.; Korneev, A.A.; Kunchenko, A.V.; Kunchenko, V.V.; Kunchenko, Y.V.; Marinin, V.G.; Kovalenko, V.I.; Bortnytska, M.O.; Ryzhova, T.P.; Lashenko, I.A. (Вопросы атомной науки и техники, 2020)
    In the work, the surface of samples made of 25X1MF steel was saturated with chromium. For this, the method of vacuum activated diffusion chromium plating was used. In this process, sodium chloride was used as an activator. ...
  • Properties of 15Cr12WNiMoV steel after vacuum activated chromium plating of its surface 
    Rudenky, S.G.; Kartzev, N.F.; Korneev, A.A.; Kunchenko, A.V.; Kunchenko, Y.V.; Marinin, V.G.; Martynenko, L.I.; Kovalenko, V.I.; Bortnytska, M.O.; Ryzhova, T.P.; Lashenko, I.A.; Gozhenko, S.V.; Krainyuk, Y.А. (Вопросы атомной науки и техники, 2021)
    In this work, we studied the properties of samples from steel 15Cr12WNiMoV after vacuum activated chromium plating at temperatures of 1070 and 1100 °C for 4 and 10 h. It was found that after chemical-thermal treatment on ...
  • Resistance of titanium alloys to cavitation wear 
    Klimenko, І.О.; Marinin, V.G.; Ovcharenko, V.D.; Kovalenko, V.I.; Kuprin, A.S.; Reshetnyak, O.M.; Belous, V.A.; Rostova, H.Yu. (Вопросы атомной науки и техники, 2022)
    The wear rate of titanium alloys VT1-0, TC5, VT6, VT14, OT4 under the action of microshocks due to cavitation, which is created in distilled water under the surface of the ultrasonic wave emitter, were determined. It was ...
