HEAT RESISTANT MEMBER, GAS TURBINE MEMBER USING THE SAME, AND MANUFACTURING METHOD OF HEAT RESISTANT MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a heat resistant member which has a porous structure capable of blowing out cooling medium from the entire surface, and has a TBC film in which strength reliability of the film is secured.SOLUTION: There is provided a heat resistant member having a thermal barrier coating film formed on a metal base via a bonding layer, which has a structure that the metal base and the bonding layer have through-holes penetrating them, the thermal barrier coating film is a porous body having a large number of voids, the large number of voids are connected via cracks, and gas flowing through the through-holes passes from a bottom part of the thermal barrier coating film to a surface part.
