HEAT-RESISTANT COMPONENT AND MANUFACTURING METHOD THEREFOR
To provide a heat-resistant component which is applicable to complex three-dimensional geometries and highly hermetical, and ensures stable strength, and also to provide a manufacturing method for the heat-resistant component.SOLUTION: A heat-resistant component 1 comprises; a core material 2; a coating layer 3 covering a surface of the core material 2; and an internal space 4 defined by the core material 2. The coating layer 3 is joined by way of an adhesion layer 5 which is formed by converting a silicon-containing adhesive to the core material 2. The core material 2 also contains SiC fibers as an aggregate and is comprised of CVD-SiC. The coating layer 3 formed from an SiC fiber-reinforced SiC composite material and is split into a plurality of portions. The heat-resistant component 1 is manufactured by: a CVD step of depositing a SiC layer 12 on a graphite-based substrate 10 by a CVD method; a separation step of removing the substrate 10 for separating the SiC layer 12 to form the core material 2; and a coating formation step of forming the coating layer 3 of the SiC fiber-reinforced SiC composite material on a surface of an adhesive material 13 to convert the adhesive material 13 to the adhesion layer 5.SELECTED DRAWING: Figure 1
【課題】複雑な立体形状にも適用でき、気密性が高く、安定して強度の得られる耐熱部品およびその製造方法を提供する。【解決手段】耐熱部品１は、芯材２と、芯材２の表面を覆う被覆層３と、芯材２で形成される内部空間４とを備える。被覆層３は、芯材２に対してシリコンを含む接着剤を転化した接着層５を介して接合されている。また、芯材２は、ＳｉＣ繊維が骨材として含まれ、ＣＶＤ−ＳｉＣからなり、被覆層３は、ＳｉＣ繊維強化ＳｉＣ複合材からなり、複数に分割されている。耐熱部品１は、黒鉛からなる基材１０にＣＶＤ法でＳｉＣ層１２を形成するＣＶＤ工程と、基材１０を除去することによりＳｉＣ層１２を分離して芯材２を形成する分離工程と、接着材１３の表面にＳｉＣ繊維強化ＳｉＣ複合材の被覆層３を形成させて接着材１３を接着層５に転化する被覆形成工程により製造される。【選択図】図１
