Abstract (en)
[Subject] A thermal spraying nozzle device and a thermal spraying system are to be provided which can supply a thermal spraying material constantly and can control the state of a film or deposit. [Solution] In a thermal spraying nozzle device wherein carrier gas is introduced into an inlet side of a nozzle to form a supersonic gas flow and a thermal spraying material is atomized and ejected by the gas flow, a storage section (4) for the storage of molten metal as the thermal spraying material is connected an end portion on the inlet side of the nozzle (2) through a connecting pipe, the nozzle has a throat portion (2a) for accelerating the introduced carrier gas to supersonic velocity and a divergent region (2b) formed downstream of the throat portion toward an outlet, the metal particles atomized by the supersonic gas being cooled to a solidified or semi-solidified state in the divergent region.
