状態にある。Conventional technology Thermal spray coating 2 is applied to the inner surface of a cylindrical ion beam to be thermally sprayed using the beam blasting method.
When carried out, the conventional method is carried out with the configuration shown in FIG. In this configuration, the ion to be thermally sprayed and the wire rod which is the thermal spraying material disposed at the center of the inner surface of the material to be thermally sprayed are electrically insulated.

面に線爆溶射法で溶射被覆することは不可能であった。In the conventional method, the wire rod is placed on the inner surface of the cylindrical material to be thermally sprayed, so if the material to be thermally sprayed is a cylindrical shape with a three-sided open, for example a U-shaped bottom, the wire rod is placed on the inner surface of the material to be thermally sprayed. It is impossible to thermally spray the inner surface of the material to be thermally sprayed unless a large hole is made and the wire is passed through. However, there is a method of inserting the 7114ITJ inside, that is, a method of using a coaxial cable as shown in Figure 2 (special d↑ number 7).
20023), a partial thermal spray coating can be achieved. Even in this case, are you connected to coaxial cable 9? l
Because of the pole 7, it is impossible to thermally coat the deep part of the U-shaped inner diameter of the material to be thermally sprayed, and the thermal spraying efficiency is also poor. Therefore, when the material to be thermally sprayed is in the shape of an upwardly open cylinder with a bottom, for example, it has been impossible to thermally spray the inner surface of the material by the wire bombardment spraying method in an industrial manner.

It is characterized by forming. That is, to explain the structure in detail with reference to FIG. 3, one electrode 13 is electrically insulated around the periphery to prevent electrical discharge with the sprayed material 12, and one end of the wire 5, which is the sprayed material, is covered. It is fixed in contact with the center of the bottom of the thermal spray material 12, and the other end is wired to the electrode 15. That is, the material to be thermally sprayed itself serves as the other electrode. Next, a large impact current necessary and sufficient to melt and explode the wire 5 is applied to achieve the desired thermal spray coating.

Therefore, even if the material to be thermally sprayed has a cylindrical shape with an open bottom, the inner surface of the material can be thermally sprayed.
