By doing so, a method of forming the heat receiving plate 2 is considered. As a shape of the manufacturing base material of the nuclear fusion device heat receiving device 1, for example, a flat plate-shaped manufacturing base material shown in FIGS. 9A and 9B is used.

The cooling pipe 4 is attached so as to penetrate the opposing surface of the heat sink 3. In the heat sink 3 which is the flat plate type manufacturing substrate shown in FIG. 9A, the heat receiving plate forming surface 6 for forming the heat receiving plate 2 is formed on the upper surface when the surface through which the cooling pipe 4 penetrates is defined as the side surface. There is a heat receiving plate 2 on the heat receiving plate forming surface 6.
The heat receiving plate 2 is formed by depositing the material of (1), and the heat receiving device 1 of the nuclear fusion device shown in FIG. 8 is manufactured.

膜厚は通常数十〜数百μｍオーダである。The film-forming method by thermal spraying is a method generally used for the purpose of surface modification of industrial materials. This film forming method generally uses a single material as a thermal spray coating material. The film thickness formed by this film forming method is usually on the order of tens to hundreds of μm.

れが生じやすい。In the heat receiving device 1 of the nuclear fusion device, the thermal expansion material of the heat receiving plate 2 and the heat sink 3 of the manufacturing base material are greatly different in linear expansion coefficient. When performing film formation by thermal spraying between such different materials, peeling or cracking is likely to occur from the end of the interface between the formed thermal spray coating and the thermal spray base material during or after thermal spraying.

ある。On the other hand, in the heat receiving device 1, there is a large temperature difference between the surface of the heat receiving plate 2 and the cooling pipe 4, and a large thermal stress is generated. In order to alleviate this thermal stress, a method of mixing a thermal spray material and a thermal spray base material and performing thermal spray has been considered.
In the manufacture of the heat receiving device 1 of the nuclear fusion device, the material of the heat receiving plate 2 and the material of the heat sink 3 are mixed and sprayed to form a thermal spray coating to form the heat receiving plate 2.

なるように受熱板２を形成していく方法である。The manufacturing method of the heat receiving device 1 by the mixed spraying is as follows:
For example, thermal spraying is performed while continuously changing the material mixing ratio of tungsten, which is the material of the heat receiving plate 2, and copper, which is the material of the heat sink 3. The material mixing ratio is 100% tungsten on the heat receiving plate 2 side and 1 copper on the heat sink 3 side.
Gradient thermal spraying is carried out while continuously or stepwise changing so as to be 00%. And on the heat receiving plate 2 side, 10
This is a method of forming the heat receiving plate 2 so that 0% tungsten and 100% copper are formed on the heat sink 3 side.

界面で剥離や割れが生じやすいという問題点がある。However, the method of forming a film by gradient thermal spraying in which different kinds of materials are mixed has a problem different from the thermal spraying of a single material. For example, when using a low melting point material and a high melting point material such as copper and tungsten, the problem that peeling or cracking easily occurs at the interface where the material mixing ratio of the thermal spray coating material changes and the interface between the thermal spray base material and the thermal spray coating There is a point.

When a film is formed, peeling or cracking is likely to occur from the end portion of the interface between the formed sprayed coating and the sprayed base material during or after the spraying. Further, peeling and cracking are likely to occur also at the interface where the material mixing ratio of the thermal spray coating material changes and the interface between the thermal spray base material and the thermal spray coating. Further, it has been difficult to form a thermal spray coating having a film thickness on the order of several mm or several mm.

The same phenomenon is likely to occur not only in the flat plate-type manufacturing base material shown in FIG. 9A but also in the manufacturing base material of the nuclear fusion device heat-receiving device 1 in which the heat-receiving plate forming surface 6 is curved, for example. It is undeniable that the quality and reliability of the formed heat receiving plate 2 may deteriorate.

い。In the conventional method of manufacturing the heat receiving device 1 of the nuclear fusion apparatus by thermal spraying, the above-mentioned peeling and cracking of the heat receiving plate 2 are prominent in the thermal spraying of a combination of different materials. This is largely due to the presence of free edges at the interface where the material mixing ratio of the coatings formed by mixed spraying changes and the interface between the sprayed coating and the sprayed base material.
