Kind Code:
A1
Abstract:
The present invention inhibits the problem of peeling of a ceramic layer, while improving heat resistance, in a ceramic component which is to be placed in a high-temperature environment. The ceramic component 1 according to the present invention, which is to be placed in a high-temperature environment 5, is provided with: a first member 3 made of a first material 21; and a ceramic layer 9 which is joined to a surface 7 of the first member 3 to be exposed to the high-temperature environment 5, and is made of a ceramic material 23 that is more heat-resistant than is the first member 3, wherein a joint portion of the first member 3 and the ceramic layer 9 is made of a composite material having the first material 21 and the ceramic material 23, and is gradational in composition in which the proportion of the first material 21 gradually becomes smaller and the proportion of the ceramic material 23 gradually becomes greater, in the direction from the first member 3 toward the ceramic layer 9.
