摘要： To provide a thermal spraying nozzle device and thermal spraying equipment on which a thermal spraying material can be supplied constantly and filming or deposition state can be controlled. In a thermal spraying nozzle device for forming an ultrahigh speed gas stream by introducing carrier gas to the inlet side of a nozzle and then atomizing a thermal spraying material by that gas stream and discharging the atomized thermal spraying material, a storage section (4) for storing molten metal as the thermal spraying material is connected to the inlet side end of the nozzle (2) through a communication passage, the nozzle has a throat portion (2a) for accelerating the introduced carrier gas to supersonic velocity, and a diameter-expanded channel portion (2b) formed on the downstream side of the throat portion toward the outlet direction. The thermal spraying nozzle is characterized in that the metal particles atomized by the supersonic gas stream are cooled down to solidification or semi-solidification state at the diameter-expanded channel portion.
