There are those that reach, and those that collide with the sprayed part and bounce off and scatter. In this way, the thermal spray material that is projected and flown is surrounded by the gas that is directed and jetted from the tip of the thermal spray gun to the thermal spray material, and the thermal spray material is guided by the surrounding gas while being projected to the thermal spray object. For example, room temperature air or an inert gas such as nitrogen gas can be used. Further, by surrounding the thermal spray material projected from the tip of the thermal spray gun to the thermal spray object with a guide body, and directing the above-mentioned gas from the thermal spray gun tip to the thermal spray object along the inner wall of this surrounding guide body, it becomes more accurate. It is possible to guide the thermal spray material to improve the yield and the like. That is, it is possible to prevent the thermal spray material from scattering and adhering to the guide body by the gas that is directed and injected along the inner wall of the guide body, and to more reliably surround the thermal spray material with the gas. Thus, the spraying of gas accelerates the sprayed material for projection flight in the projection direction, and the directivity in the projection direction becomes accurate by the guide by the gas. In this way, the spray material that is projected and fly is guided by the gas and is accelerated, so the spread of the spray material between the tip of the spray gun and the object to be sprayed is reduced, and the spray material is accurately projected onto the spray part. In addition, since the projection speed is accelerated from the initial speed and the final speed is increased, the projection speed bites into the sprayed part, the splashes and splashes are reduced, and the yield is dramatically improved. Further, by accelerating the projection speed, the spraying time for obtaining a sprayed film having a predetermined film thickness can be shortened, the productivity can be improved, and the projection speed becomes high, so that the sprayed material collides with the sprayed object. The force is increased, the generation of pores in the sprayed film is reduced, and the adhesion of the sprayed film can be improved. For this reason, it is extremely advantageous when the sprayed portion of the sprayed object has a curved surface shape or the like and the spraying range is narrow.

With a, the spraying material can be reliably prevented from scattering, and the projection speed can be accelerated. If it is less than 0.3 MPa, it will be difficult to obtain a sufficient effect. Can be prevented from scattering.
