Abstract: A thermal barrier coating material contains a compound X that is a cation-deficient-type defective perovskite complex oxide. Unit cells of the compound X each include six oxygen atoms and has a structure in which two octahedrons sharing one oxygen atom are aligned. In the compound X, central axes of two octahedrons that belong to adjacent unit cells, respectively, and are adjacent to each other are inclined relative to each other. A plurality of sets of the two octahedrons that belong to the adjacent unit cells, respectively, and are adjacent to each other are arranged to form a periodic structure in which octahedrons having different inclinations are alternately arranged, and the compound X has a boundary surface at which a periodicity of the periodic structure changes, in a crystal structure thereof.

Abstract: A thermal barrier coating includes: a metal bonding layer made of an alloy containing Al; a thermal barrier layer; and an intermediate layer provided between the metal bonding layer and the thermal barrier layer. The thermal barrier layer contains a compound represented by the following general formula (1), LnxTayHfzO(3x+5y+4z)/2 (1) (wherein Ln is an atom of one element selected from among rare earth elements, x is 0 to 1.0, y is 0.8 to 3.0, and z is 0 to 7.0). The intermediate layer contains at least one layer selected from among the following (A) to (C): (A) a layer containing hafnium oxide (HfO2) as a main component; (B) a layer containing, as a main component, a compound consisting of tantalum (Ta), hafnium (Hf), and oxygen (O); and (C) a layer containing, as a main component, a compound consisting of a rare earth element, tantalum (Ta), hafnium (Hf), and oxygen (O).

Abstract: An environmental resistant coating member includes a SiC long fiber-reinforced ceramics substrate and an environmental barrier coating layer provided on the whole surface of the SiC long fiber-reinforced ceramics substrate. The environmental barrier coating layer includes a SiAlON bonding layer laminated on the SiC long fiber-reinforced ceramics substrate, a mullite layer laminated on the SiAlON bonding layer, a reaction inhibition layer laminated on the mullite layer, and a gradient layer formed on the reaction inhibition layer that gradually changes from a rare-earth disilicate to a rare-earth monosilicate. The reaction inhibition layer includes at least one of an alumina layer, a garnet layer, and a rare-earth (mono)silicate layer. When the reaction inhibition layer includes two or more of these layers, the layers are formed in the order of the alumina layer, the garnet layer, and the rare-earth (mono)silicate layer from a mullite layer side toward a gradient layer side.
