    • [PROBLEMS] A thermal spray nozzle device capable of accurately forming a uniform and compact metal laminate, and a thermal spray device using the thermal spray nozzle device. [MEANS FOR SOLVING PROBLEMS] A thermal spray nozzle device in which a carrier gas is introduced into the entrance side of a nozzle (1) to form a supersonic gas flow in the entire region inside the nozzle and a thermal spray material is atomized and ejected by the gas flow. The thermal spray nozzle device has a thermal spray material insertion section (5) through which the thermal spray material (4), formed in a linear shape, is inserted into the nozzle (1) from the entrance side so as to be substantially parallel to the gas flow, and has a laser device for heating and melting, in the vicinity of the fore-end of the thermal spray material insertion section (5), the thermal spray material (4) projecting from the thermal spray material insertion section (5). Thermal spray material particles that are melted and atomized by the laser device are quickly cooled by the gas flow in the nozzle (1) and ejected in a coagulated state or a semi-coagulated state.
    • 本发明提供一种能够精确地形成均匀且紧凑的金属层压体的热喷嘴装置,以及使用热喷嘴装置的热喷涂装置。 解决问题的手段一种热喷嘴装置,其中载气在喷嘴(1)的入口侧引入,以在喷嘴内部的整个区域中形成超音速气流,并且喷射喷射材料 通过气流。 热喷嘴装置具有热喷涂材料插入部分(5),形成为直线形状的热喷涂材料(4)从入口侧插入到喷嘴(1)中,以便基本平行于 气流,并且具有用于加热和熔化的激光装置,在热喷涂材料插入部分(5)的前端附近,从热喷涂材料插入部分(5)突出的热喷涂材料(4) )。 通过激光装置熔化和雾化的热喷涂材料颗粒被喷嘴(1)中的气流快速冷却,并以凝固状态或半凝固状态喷射。
