Abstract

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