Beschreibung
Zusammenfassung:	A cold spray apparatus for applying a coating of particles to a substrate includes a nozzle assembly having a plurality of inner passages terminating at a common exit. The nozzle assembly includes a particle supply members in communication with the inner passages. The particle supply members supply the particles to flow and accelerate through the inner passages and out of the nozzle assembly via the common exit toward the substrate to be coated thereon. Furthermore, each inner passage includes a laser that emits a laser beam that is transmitted through the inner passage. The laser heats at least one of the particles and the substrate to promote coating of the substrate with the particles.
