This article is devoted to the equipment for gas-dynamic spraying in order to simplify its design, to provide the possibility of adjusting the parameters (temperature, pressure, speed, ejection) of the air-polymer flow, and to clarify the fundamental possibility of creating polymer functional coatings with gas-dynamic spraying.
The polymeric materials, depending on their brand, are completely inert and do not react in any chemical reaction with food, animal waste products, acids and other corrosive media. It is known that polymeric materials can be attributed to the two main classes of reactants and thermoplastics. If the thermoplastic process of heating and cooling can occur repeatedly without changing their structure, then reactive plastics with a single heating with increasing time of elevated temperatures as a result of chemical processes occurring in them, transform into an insoluble solid state with the formation of a mesh structure of macromolecules. This process is irreversible, the products of the reactoplasts are destroyed by reheating at a sufficiently high temperature without first softening and thus cannot be recommended for their use in order to create polymer coatings by gas-dynamic sputtering.
The characteristics of the most common thermoplastics, such as polypropylene, polyethylene, polytetrafluoroethylene, polystyrene, polyvinyl chloride, polyamides, are analyzed, and the conditions to be created for the successful application of functional polymer coatings. Experimental application of polymer coatings of the most common polymers. The results obtained indicate that the designed and manufactured prototype gasdynamic spraying device is capable of creating different modes of polymer coating.
That is to change and maintain the required temperature and pressure of compressed air. The results of the researches show a fundamental possibility to create polymer coatings from thermoplastics on metal surfaces by gas-dynamic spraying.

Technology, energy, agriculture transport AIC is a scholarly professional journal with a long-standing history and stable academic tradition, reflecting the evolution of engineering and technical sciences within the agro-industrial sector of Ukraine.
The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production. During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured. Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016). The change of title reflected the expansion of the journal’s thematic coverage and its orientation toward interdisciplinary research in mechanical engineering, energy systems, electrical engineering, transport technologies, automation, and digital solutions for the agro-industrial complex.
