The study presents the results of an assessment of the probability of collision of heterogeneous particles of composite materials when obtaining coatings by detonation on the cumulative lining of perforation systems used in the opening of oil and gas reservoirs. Due to the different properties of the initial metal powders used to produce coatings, the interaction of their particles with each other in the gas-thermal flow can lead to premature chemical reactions, which will lead to a deterioration in the strength properties of the resulting coating. Therefore, a preliminary calculation of the probability of collision of metal powder particles makes it possible to conclude about their quantitative characteristics before obtaining a coating, as well as the possible transition of interacting particles into intermetallic phases, which subsequently affect the adhesion characteristics of the coating.
