Abstract
Mathematical model is suggested, describing interaction of powder particles with detonation products inside the channel of a detonation unit and in the space between an exit section of the channel and a workpiece. Calculation and experimental results are compared. Peculiarities of behaviour of powder particles in detonation spraying are numerically studied
Keywords: detonation spraying, coating, process parameters, optimisation, mathematical model, parameters of flow of particles
