Also, the possibility of controlling the properties of restored surfaces owing to choice of the related equipment with required structure and characteristics in order to prolong the service life of machinery parts is shown. The right choice of equipment for spraying makes it possible to increase the speed and temperature of the spraying gas and particles, reduce the droplet diameter, increase the density and reduce the oxidation of coatings. The influence of spray factors such as the flow rate and pressure of working gases, composition of combustion mixture, spraying distance, dispersion of the spray, properties of wire material, etc. on the properties of the coatings obtained has been investigated.</p>}, number={1/107}, journal={Problems of Tribology}, author={Lopata, A. and Smirnov, I. and Holovashchuk, M. and Lopata, V.}, year={2023}, month={Mar.}, pages={73–80} }
