    • Features of Measuring the Hardness of a Metal Surface Modified with Ultrafine Particles of Minerals 

      Skazochkin, A. V.; Bondarenko, G. G.; Zukowski, P. (БНТУ, 2020)
      One of the important characteristics of the surface properties of metal parts subjected to friction is hardness. Hardness measurements are important for determining the operational characteristics of parts and monitoring the technological regimes of surface modification. However, hardness measurements of thin modified layers made by different methods can lead to differences in ...

    • Measurement stand for study properties of isolation materials using polarization method 

      Zukowski, P.; Koltunowicz, T.; Kozak, Cz.; Kierczynski, K.; Rogalski, P. (БНТУ, 2014)
      The article presents measurement stand, which is used to measure polarization and depolarization currents, using PDC method, in wet transformer oil-impregnated cellulose isolation. Maximum resolution of measured currents reaches 10-15 A. The accuracy of thermal stabilization, in three-electrode capacitor system, comes to 0,001 °C.

    • Modeling of an Impact of Thin Insulating Film on the Electrode Surface on Discharge Ignition in Mercury Illuminating Lamps at Low Ambient Temperatures 

      Bondarenko, G. G.; Fisher, M. R.; Kristya, V. I.; Zukowski, P. (БНТУ, 2019)
      The mixture of argon and mercury vapor with temperature-dependent composition is used as the background gas in different types of gas discharge illuminating lamps. The aim of this work was to develop a model of the low-current discharge in an argon-mercury mixture at presence of a thin insulating film on the cathode and to investigate the influence of film on the discharge ignition ...

    • Research of Surface Wear Resistance of Aluminum Alloy Modified with Minerals using Sclerometry Method 

      Skazochkin, A. V.; Bondarenko, G. G.; Zukowski, P. (БНТУ, 2019)
      Improving the wear resistance of the surface of metal parts used in various industries is one of the relevant areas of materials science. The aim of this work was a comparative study of the wear resistance of a sample of an aluminum alloy (EN AW-2024, an aluminum alloy of the Al-Cu-Mg system) modified with ultrafine particles of minerals using the sclerometry method, which makes ...
