THERMAL BARRIER COATING MATERIAL, METHOD OF PRODUCTION THEREOF, AND GAS TURBINE MEMBER AND GAS TURBINE APPLYING THE THERMAL BARRIER COATING MATERIAL

摘要

Disclosed is a thermal barrier coating (TBC) raw material for coating a gas turbine member that provides a higher thermal barrier property and a higher peeling resistance. The thermal barrier coating (TBC) raw material comprises a zirconia powder having a specific surface area of at least 10 m2/g and a rare earth oxide having a specific surface area of at least 10 m2/g.
