get. Here, it is preferable that the mold 7 has a large difference in coefficient of thermal expansion from the material constituting the first sprayed layer 2, and for example, a ceramic material such as alumina is preferably used. Then, when the mold 7 is peeled off from the thermal sprayed layer 2.4.5, it is rapidly cooled and is easily peeled off due to the difference in the coefficient of thermal expansion, thus eliminating the need to apply a mold release agent on the mold 7 in advance. Further, when the mold 7 is formed of a ceramic material, the mold 7 may be peeled off by a method such as elution with an alkaline solution in addition to the above-mentioned rapid cooling. In this case, the mold 7 is attached to the sprayed layer 2.

できる。"Effects of the Invention" As explained above, the invention of claim 1 of the present invention is to thermally spray two or more different materials on a base material in sequence to form a plurality of layers, and then to form a plurality of layers. Since the formed base material is subjected to thermal 1111 isostatic press treatment to form a composite material, it is not only possible to form multiple layers by thermal spraying, but also to easily form a desired material onto a complex-shaped base material. A sprayed layer can be formed. In addition, by performing hot isostatic pressing, even if the sprayed layer is porous, it can be made denser and the bonding strength between the garnishing material and the sprayed layer can be strengthened. Can be done. Furthermore, it is possible to create multiple layers in one process, but since encapsulating and sealing are not necessary when performing hot isostatic pressing, it is possible to suppress the rise in production costs and make it easier! i can manufacture products.

; Two or more different types. The material is thermally sprayed sequentially to form 1 (number of layers), and then hot isostatic pressing is performed on the mold on which the plurality of layers have been formed, and then the mold is peeled off to obtain a composite material. Therefore, it is possible to easily produce hollow composite materials by peeling off the mold, and the product shape can be changed during manufacturing. You can have more freedom.
