Abstract: A low pressure plasma spraying method includes turning working gas into plasma by direct-current arc to generate a plasma jet while setting a plasma power source output to 2 to 10 kW in a pressure reducing vessel and feeding raw material powder having an average particle size of 1 to 10 μm into the plasma jet from feeding ports of a thermal spraying gun to form a thermal sprayed coating, which can suppress transformation of the raw material powder and form a dense coating.

Abstract: A temperature control unit has a temperature control unit body, a temperature control part provided inside the temperature control unit body, which raises and lowers a surface temperature of the temperature control unit body on a side where a temperature control object is located, and a thin coating temperature measuring resistance part composed of a thermal sprayed coating. The thin coating temperature measuring resistance part is formed over a certain range in a surface on the side where the temperature control object is located, and which is provided inside the temperature control unit body on a side closer to the temperature control object than the temperature control part. The thin coating temperature measuring resistance part can accurately measure an average temperature of a temperature control surface.

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.
