    • Calculation of Particle Flow Temperature during Plasma Spraying of Mixture Consisting of Self-Fluxing Powder and Ceramics 

      Kalinichenko, A. S.; Krivosheyev, Yu. K.; Meshkova, V. V.; Devoino, O. G. (БНТУ, 2018)
      Plasma spraying is one of the most effective methods allowing both to restore worn surfaces of parts and create wearresistant coatings on new parts aiming the increase of their service life. Properties of the produced coatings depend on number of parameters, such as a plasma temperature, a chemical and fractional composition of the sprayed mixture, a distance from a plasma torch ...

    • Development of Wear Resistant Coatings Formed by Plasma Spraying of Alloy Ni–Fe–Cr–Si–B–C System Reinforced with Ceramics Al2O3 

      Kalinichenko, A. S.; Devoino, O. G.; Meshkova, V. V. (БНТУ, 2016)
      Создание функционально ориентированных, в том числе наноструктурированных, антифрикционных материалов и покрытий, обладающих качественно новым комплексом служебных свойств, является важной научной и практической задачей. В частности, для кабельного производства актуальна задача обеспечения высоких эксплуатационных свойств быстроизнашивающихся протягивающих и поддерживающих роликов ...

    • Improving Properties of Tool Steels by Method of Dynamic Alloying 

      Kalinichenko, A. S.; Ovchinnikov, V. I.; Usherenko, S. M.; Yazdani-Cherati, Javad F. (БНТУ, 2019)
      The influence of high-speed particle fluxes on changes in the structure and properties of materials has been widely studied currently. The effect exerted by particles moving at very high speeds can have both negative (in spacecrafts) and positive character (dynamic processing of tool steels). Therefore a task for studying an effect of high-speed particle flows on structure change ...

    • Some Specific Features of Bearing Unit Development Based on Sliding Friction Pairs for Precision Electro-Spindles 

      Kalinichenko, A. S.; Basiniuk, U. L.; Mardasevich, E. I. (БНТУ, 2019)
      Various types of bearing units are used for movable connections in mechanical engineering, and sliding pairs (sliding bearings, guides, bushings) are rather widely applied for this purpose. This allows increasing stiffness of units to reduce their dimensions, to improve heat dissipation and ensure reduction in noise and vibration. However in some cases while using a sliding ...
