    • 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 ...

    • Evaluation of Evaporative Degradation of Arc Torch Cathodes in Hydrocarbon-Containing Plasmas for Spraying, Thermal Protection Testing and Related Technologies 

      Gorbunov, A. V.; Gorbunova, V. A.; Devoino, O. G.; Petraconi, Filho G.; Halinouski, A. A. (БНТУ, 2022)
      Design of non-transferred DC electric arc plasma torches (EAPTs) operated with plasma gases containing alkane hydrocarbons, as a promising type of heaters for a number of technologies (thermal spraying, surface hardening, testing of thermal protection systems, etc.), requires taking into account the evaporation rate of surface cathode material (as one of the channels of its ...

    • Investigation of Upgraded Technology for Plasma Spraying of Bronze Powder Using the Combined Process with Hydrocarbon Additions 

      Devoino, O. G.; Gorbunov, A. V.; Chenchong, Wang; Volodko, A. S.; Polyakov, A. N.; Gorbunova, V. A.; Seniut, V. T.; Kovaleva, S. A.; Koval, V. A. (БНТУ, 2023)
      The object of the research is thermal spray process for the formation of metal coating from bronze powder in plasma-fuel variant, using direct current (DC) electric arc plasma torch, on steel samples. The aim of the work was to investigate and develop the technology for plasma-fuel spraying of functional coatings (for wear-resistant and antimicrobial applications) on machine-building ...

    • Thermodynamic Estimation of the Parameters for the C–H–O–N–Me-Systems as Operating Fluid Simulants for New Processes of Powder Thermal Spraying and Spheroidizing 

      Gorbunov, A. V.; Devoino, O. G.; Gorbunova, V. A.; Yatskevitch, O. K.; Koval, V. A. (БНТУ, 2021)
      Over the past few years, a group of new processes was developed for high-temperature, including plasma electric arc spraying (at ambient pressure) and spheroidizing of some ceramic and metal powder materials with the use of gaseous hydrocarbons in the heat carriers as well as with feeding of organic additions into a high-temperature jet, in particular, polymeric ones, to control ...
