Title:
HEAT-RESISTANT MEMBER AND POWER GENERATION SYSTEM
Document Type and Number:
Japanese Patent JP2022178306
Kind Code:
A
Abstract:
To provide a heat-resistant member, etc., capable of sufficiently improving both thermal insulation and durability.SOLUTION: A heat-resistant member in an embodiment includes a thermal insulation coating layer formed on a base material. The thermal insulation coating layer includes: a bonding layer provided on the surface of the base material; and a ceramic layer provided through the bonding layer on the surface of the base material and having spherical pores and layered pores formed in the inside; and a value R of percentage of a layered porosity RL being a ratio of a layered pore occupied in the ceramic layer to a total porosity RT being a ratio of both the spherical pores and the layered pores occupied in the ceramic layer satisfies the following relation expression (A), 100(RL/RT)=R≤50...the formula (A); and the spherical pores and the layered pores are distributed in the thickness direction so that the value R is larger as separated from the bonding layer.SELECTED DRAWING: Figure 1
