1.抵抗力のある焼結セラミック材料の使用により、遮熱層の温度抵抗を改善することができる。これにより、遮熱層材料の圧縮増大、ひいては高い温度における遮熱層の振動過程を制限することができる。
−7YSZ/La2Hf2O7;
−7YSZ/BaZrO3;
−7YSZ/LaYbO3、
この場合、7YSZ=酸化イットリウム7重量%を用いて安定化された酸化ジルコニウムである。1000℃の温度では、熱膨張率CTEは以下の通りである:
−CTE7YSZ〜10−5K−1;
−CTELaHfO〜8.0・10−6K−1;
−CTEBaZrO〜8.3・10−6K−1;
−CTELaYbO〜8.6・10−6K−1。
図2は、遮熱層の表面における、ガスタービンの典型的な運転条件のもとで生じる歪みを表すx−y線図である。
−7YSZ/La2Hf2O7、ただしCTELaHfO(1000℃)〜8.0・10−6K−1;
−7YSZ/BaZrO3、ただしCTEBaZrO(1000℃)〜8.3・10−6K−1;
−7YSZ/LaYbO3、ただしCTELaYbO(1000℃)〜8.6・10−6K−1。
