摘要： Disclosed is a nozzle for cold spray and a cold spray apparatus using the same. The nozzle for cold spray includes a hollow-type nozzle section. The nozzle section includes a convergence inlet section in which the cross-sectional area is converging, a throat area connected to the convergence end point of the inlet section, and an outlet section connected to the end point of the throat area. The nozzle for cold spray is provided with a spray tube located inside the convergence inlet section, the spray tube having a spray hole formed at its end point in such a way as to be placed at the throat area or the outlet section beyond the throat area. The speed of the powder flow at the outlet end point of the outlet section reaches 300-1,200 m/s.
