N2 - The effect of the spraying direction on the motion of particles in a plasma flow is determined to estimate the effect of gravity. Three directions (up, down, horizontal) of spraying are chosen. A titanium PTM-1 TU 14-22-57-92 powder is considered. For each of the considered spraying directions, the motion of titanium powder particles of various dispersions in a plasma flow is calculated by a finite-element method using the SolidWorks software. The powder particles to be sprayed have sizes of 1, 50, and 90 μm. The change in the powder particle temperature when moving in a plasma flow is studied as a function of the spraying direction. A comparative analysis is performed for the considered spraying directions, and the results are used to describe the advantages and disadvantages, and the recommendations are given for performing the processes of producing a powder and a coating. The obtained data can be useful for choosing the substrate position for depositing functional coatings. The effect of gravity on the separation of the synthesized powders and the distribution of the plasma flow temperature in the zone under study is demonstrated. To verify the calculation results, a full-scale experiment is carried out on the installation assembled at the Institute of Metallurgy, which is used to produce a powder and to deposit coatings, taking into account its design features. The results are useful for the developers and consumers of technological equipment. © 2023, Pleiades Publishing, Ltd.
