Claim:
1. A process for cold spraying a substrate, comprising: feeding metallic coating particles to a convergent-divergent nozzle device, the metallic coating particles being fed without a plastic encapsulation; supplying a dispersion, comprising a liquid suspension agent and plastic particles dispersed in the liquid suspension agent, to the nozzle device while the metallic coating particles are being fed to the nozzle device, the plastic particles being smaller than the metallic coating particles; accelerating the metallic coating particles with the nozzle device in a cold gas jet, while allowing the plastic particles to accumulate on the coating particles, thereby forming plastic encapsulated coating particles before the metallic coating particles contact the substrate; and depositing the encapsulated coating particles on the substrate to from a layer having a metallic first microstructure phase and a second microstructure phase made of a plastic.
