FIELD: process engineering.
SUBSTANCE: invention relates to cold gas spraying unit and method of cold gas spraying, Proposed unit 1 has cold gas spraying appliances (25, 26, 29, 32, 35, 35', 36). Said appliances ensure periodic or aperiodic variation in one of properties of cold gas flow 7 with particles, say, temperature (T), pressure (p), particle density (ρ), particle material (M), rate (v) of cold gas flow (7).
EFFECT: varied cold gas flow conditions.
