摘要：The object of the present invention is to provide a cold spray method in whichspray efficiency is improved by using a device comprising a similar construction to theconventional ones with minor change in conditions. The cold spray method employs thenozzle for cold spray system which comprises a convergent shape part, a throat part anda conical divergent shape part widen forward from the throat part used for making theraw material powder introduce from a inlet of the nozzle which locates in the convergentshape part into and shoot the powder as a supersonic flow by using a working gas havingtemperature equal to or lower than a melting point of the raw material powder from aspout provided at the tip of the divergent shape part, wherein the convergent shape partis composed of a preheating region and a convergent region.
