    • 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 ...
