The investigation of processes having place during a supersonic deposition of solid coatings is carried out. The methods of computational gas dynamics, gas dynamics of disperse media, the theory of stress-strain state and the mechanics of solids are used. Mathematical modelling of a three-dimensional flow of a viscous two-phase compressible turbulent medium consisting of a real gas—air and deformable destructible conjugating solid particles of powder is carried out. Fields of parameters and kinetic characteristics of the motion of a two-phase medium in both the Dymet nozzle and a free flow zone between the nozzle and a solid substrate are obtained.

Key words: sputtering, two-phase flow, mathematical modelling, supersonic flow, Dymet nozzle.
