THERMAL SPRAY NOZZLE DEVICE AND THERMAL SPRAY DEVICE USING THE SAME

摘要

[Subject] A thermal spraying nozzle device capable of accurately forming a uniform and compact metal laminate, as well as a thermal spraying system using the thermal spraying nozzle device, are to be provided. [Solution] A thermal spraying nozzle device wherein carrier gas is introduced into an inlet side of a nozzle (1) to form a supersonic gas flow in the entire region inside the nozzle and a thermal spraying material is atomized and ejected by the gas flow, the thermal spraying nozzle device comprising a thermal spraying material inserting section (5) for insertion therethrough of the thermal spraying material (4) formed in a linear shape into the nozzle (1) from the inlet side substantially in parallel with the gas flow and a laser device for heating and melting the thermal spraying material projected from the thermal spraying material inserting section in the vicinity of a front end of the thermal spraying material inserting section, particles of the thermal spraying material melted and atomized by the laser device being cooled quickly by the supersonic gas flow in the nozzle (1) and ejected in a solidified or semi-solidified state.
