CERAMIC COMPONENT AND METHOD FOR THREE-DIMENSIONALLY MANUFACTURING CERAMIC COMPONENT
PROBLEM TO BE SOLVED: To suppress a problem of peeling of a ceramic layer in a ceramic component placed in a high-temperature environment, while increasing heat resistance of the component.SOLUTION: A ceramic component 1 of the present invention is to be placed in a high-temperature environment 5 and includes a first member 3 composed of a first material 21 and a ceramic layer 9 that is joined to a surface 7 of the first member 3 to be exposed to the high-temperature environment 5 and is composed of a ceramic material 23 having higher heat resistance than that of the first member 3. The joined part of the first member 3 and the ceramic layer 9 is composed of a composite material having the first material 21 and the ceramic material 23 and is configured to have a gradient composition in which in a direction from the first member 3 to the ceramic layer 9, an abundance percentage of the first material 21 gradually decreases while an abundance percentage of the ceramic material 23 gradually increases.SELECTED DRAWING: Figure 1
【課題】高温環境に置かれるセラミックス部品において、耐熱性を向上させつつセラミックス層の剥離の問題を抑制する。【解決手段】本発明のセラミックス部品１は、高温環境５に置かれるセラミックス部品であって、第１材料２１で構成される第１部材３と、第１部材３の高温環境５に晒される側となる面７に接合され、第１部材３よりも耐熱性の高いセラミックス材料２３で構成されるセラミックス層９と、を備え、前記第１部材３とセラミックス層９の接合部分は、第１材料２１とセラミックス材料２３を有する複合材料で構成され、第１部材３からセラミックス層９に向かう方向において第１材料２１の存在割合が徐々に減り、セラミックス材料２３の存在割合が徐々に増える傾斜組成に構成されている。【選択図】図１
