| 摘要 |
The present invention provides a member coated with thermal barrier coating film having a metal substrate, the surface of which is covered with an adhesive layer (bond coat layer) composed of a heat resisting alloy and a thermal barrier film layer (thermal barrier coating layer) composed of a heat resisting ceramic formed on the adhesive layer, and a thermal spraying powder used for the formation of the adhesive layer, characterized in that the adhesive layer is a MCrAlX alloy (wherein M is at least one metal selected from among Fe, Ni and Co, and X is at least one metal selected from among Y, Hf, Ta, Cs, Pt Zr, La and Th), and an element capable of inhibiting the growth of an oxide layer (TGO) which is grown between the adhesive layer and the thermal barrier film layer by the exposure to a high temperature is added to the adhesive layer.
