Title:

THERMAL BARRIER COATING MATERIAL, THERMAL BARRIER COATING, TURBINE MEMBER, AND GAS TURBINE

Document Type and Number:

WIPO Patent Application WO/2010/116568

Kind Code:

A1

Abstract:

Provided is a thermal barrier coating material which has more excellent high-temperature crystal stability than that of YSZ, and which exhibits high toughness and thermal barrier effect. Also provided are a thermal barrier coating which has a ceramic layer formed using the thermal barrier coating material and which exhibits excellent durability in terms of heat cycle, and a turbine member and a gas turbine which are each provided with the thermal barrier coating. The thermal barrier coating material comprises, as the main component, ZrO2 which contains both Yb2O3 and Sm2O3 as stabilizers, the total contents of the stabilizers being 2 to 7mol% and the content of Sm2O3 being 0.1 to 2.5mol%.
