The invention relates to a method of, and a nozzle arrangement for, spraying cold gas. The nozzle arrangement has a first nozzle (1, 3, 5) and a second nozzle (2, 4, 6), which is arranged within the first nozzle (1, 3, 5). The first nozzle (1, 3, 5) is fed a gas which optionally contains particles. The second nozzle (2, 4, 6) is fed a particle-containing gas. The particles are applied to a surface of the substrate by means of the gases. |
