摘要
A cold spray nozzle assembly for applying a coating of particles to a substrate includes a nozzle defining an inner passage with a nozzle exit. The nozzle assembly also includes a particle supply member in communication with the inner passage. The particle supply member supplies the particles to flow and accelerate through the inner passage and out of the nozzle via the nozzle exit toward the substrate to be coated thereon. Furthermore, the nozzle assembly 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.
