【 摘 要 】

The initial stage of the formation of polymeric powder coatings is considered. The equations for estimating the convergence velocity of the particles and the obstacle at impact, as well as other characteristics were obtained when depositing the particles on the body surface. Using fictitious bubble and the ideal model of the porous medium we found dependencies that describe the coalescence dynamics of the deposited softened powder particles, determined at the time of their full agglutination.
