摘要
The object of the present invention is to provide a cold spray method in which spray efficiency is improved by using a device comprising a similar construction to the conventional ones with minor change in conditions. The cold spray method employs the nozzle for cold spray system which comprises a convergent shape part, a throat part and a conical divergent shape part widened forward from the throat part used for making the raw material powder introduce from an inlet of the nozzle, which is located in the convergent shape part, into and shoot as a supersonic flow by using a working gas having temperature equal to or lower than a melting point of the raw material powder from a spout provided at the tip of the divergent shape part, wherein the convergent shape part is composed of a preheating region and a convergent region.
