A gas turbine member in which a bond coat, an intermediate layer and a top coat are disposed on a substrate in this order, characterized in that the intermediate layer comprises Y2O3 and Al2O3. The intermediate layer fulfills a function of trapping oxygen contained in combustion gas, and thus suppresses the growth of a TGO (Thermal Grown Oxide) layer formed at the interface of the bond coat layer. |
