概要 （図表や脚注は「報告書全文」に掲載しております）

本報告書では、当所検査法によるＴＢＣ遮熱性能の測定精度評価、実機廃却燃焼器内面全域のＴＢＣ遮熱性能検査結果等に基づく、当所検査法の実機適用性評価を実施し、以下の成果を得た。・当所検査法は、燃焼器ＴＢＣ遮熱性能を目標精度とした±5%以内で測定可能なことを確認した。・当所検査法により、燃焼器内面全域のＴＢＣ遮熱性能を定量的に測定した。ここで、ＴＢＣ熱抵抗の最大値と最小値の比は約3.5倍となり、ＴＢＣ劣化が母材寿命に影響を及ぼすこと等、貴重な情報も得られた。・当所検査法は、ＴＢＣ非破壊検査法として初めて、燃焼器ＴＢＣ遮熱性能の定量的な評価を実現し、測定精度、簡便さ、迅速さ等について実用に十分な能力を持っており、受入検査時の施工不良判断、定期検査時の補修判断等に有効な測定法と言える。

概要 （英文）

In this report, the serviceability of our proposed inspection method was evaluated based on the measurement accuracy of thermal barrier performance of thermal barrier coating (TBC) and the inspection result of the combustor inner surface TBC. The results is shown in the following. Our proposed inspection method confirmed the thermal barrier performance of combustor TBC was able to be measured within ±5% which was the target accuracy. Thermal barrier performance of the combustor inner surface TBC was quantitatively measured by our proposed inspection method. The result of the inspection shows the important informations that TBC degradation effects the substrate remaining life because the ratio of the maximum value and the minimum value of TBC thermal barrier performance was about 3.5 times. Our proposed inspection method achieved a quantitative evaluation of the combustor TBC thermal barrier performance for the first time as a TBC nondestructive inspection method. And our proposed inspection method has an ability enough for practical use in the measurement accuracy, ease and quickness, etc. So, our proposed inspection method is judged effective inspection method on the repair judgment and acceptance inspection etc..
