The interaction of a stream of high-velocity particles with the surface layer of a target was investigated. The impact of discrete particles with the sample surface was shown to lead to the formation of a coating consisting of these particles and to the changes in the physical and mechanical properties of the surface layer of the target. The obtained coatings are a composite material consisting of sintered (not melted) powder particles. The impact of high-velocity particles was shown to lead to the hardening of the surface layer of samples exposed to the stream of powder particles of tungsten, nickel and titanium nitride. The maximum increase in the microhardness of targets was observed at a depth of 2 and 4 mm from the surface treated with a stream of particles.
