    Kinetic regularities of interaction of sintered titanium with molecular nitrogen at atmospheric pressure
    (Lviv Polytechnic Publishing House, 2016) Shvachko, Khrystyna; Kovbasyuk, Taras; Karpenko Physico-Mechanical Institute of the NAS of Ukraine; Lviv Polytechnic National University
    The kinetics of gas nitriding of the sintered titanium at a temperature of 800 °C was investigated. Parameters of surface roughness and surface microhardness were evaluated.

    Structure and properties of dielectric coatings based on fusible glass-ceramic materials
    (Lviv Polytechnic Publishing House, 2016) Kovbasyuk, Taras; Klymko, Orest; Baziuk, Mychailo; Lviv Polytechnic National University
    Structure and thermal properties of the dielectric coatings on the basis of glass-ceramic system PbO-ZnO-B2O3-SiO2-Al2O3-BaO (sealant) on a stainless steel substrate were studied. The advantages and disadvantages of these surface layers in comparison with dielectric surface layers applied according to the method of magnetron sputtering are shown.

    Tribotechnical characteristics of VT22 titanium alloy after nitriding, combined with heat treatment
    (Lviv Polytechnic Publishing House, 2016) Lavrys, Serhii; Kovbasyuk, Taras; Penkovyi, Oleh; Karpenko Physico-Mechanical Institute of the NAS of Ukraine; Lviv Polytechnic National University
    Nitriding of VT22 titanium alloy, combined with its standard heat treatment in a single technological cycle was proposed. It was shown that after thermodiffusion saturation the microhardness and depth of the hardened surface layer of VT22 alloy increased, but the quality machined surface worsened. It was established that the increase time of nitriding process worsened the tribotechnical characteristics of friction pair nitrided VT22 alloy – BrAZhN 10-4-4 bronze.
