Abstract
In a method for the cold-gas spraying of particles having different solidities and/or ductilities and in a cold-gas spraying device () suitable for use in with the method, in order to obtain a comparatively high proportion of particles () having higher solidity and/or smaller ductility in comparison to the other particles (), these particles are fed into an area () of the stagnation chamber () of the cold-gas spraying device which is very distant from the nozzle (). Advantageously, the particles () have to cover a longer course through the stagnation chamber and are thus preheated. In this way, the deposition of these particles () on a substrate () is improved. Particularly metals having a transition temperature ranging between brittle and ductile behavior can be provided with ductile properties by the preheating process, thereby simplifying the deposition process.
