THERMAL BARRIER COATING MATERIAL, THERMAL BARRIER COATING, TURBINE MEMBER, AND GAS TURBINE |
摘要 |
<p>A thermal barrier coating material that exhibits superior high-temperature crystal stability to YSZ, as well as a high degree of toughness and an excellent thermal barrier effect. Also provided are a thermal barrier coating, which has a ceramic layer formed using the thermal barrier coating material and exhibits excellent durability to heat cycling, and a turbine member and a gas turbine which are each provided with the thermal barrier coating. The thermal barrier coating material comprises mainly ZrO 2 which contains Yb 2 O 3 and Sm 2 O 3 as stabilizers, wherein the amount of the stabilizers is not less than 2 mol% and not more than 7 mol%, and the amount of the Sm 2 O 3 is not less than 0.1 mol% and not more than 2.5 mol%.</p> |
