Description
単結晶超合金Rene N5試験クーポンを試験材料で被覆した。試験クーポンは、直径25ミリメートルかつ厚さ3.25mmであった。実施例1は、式Ni−40Al−6Co−5Pt−4Cr(原子%)に従った概略組成を有する50マイクロメートルの(Ni,Pt)Alコーティングを含んでいた。比較例2は、式Ni−47Ti(原子%)に従った組成を有する275マイクロメートルのNiTiコーティングを含んでいた。クーポンには、空気中で反復熱サイクルを施した。この場合、クーポンを1150℃の温度に1時間加熱し、続いて室温まで冷却した。図5は、熱サイクリング前、1サイクル後及び100サイクル後における実施例1及び比較例2を示している。比較例2はただ1回のサイクル後に激しい酸化によって破損した一方、実施例1は1150℃で100サイクル後にも無傷のままであったことが注目される。図6は、実施例1及び比較例2に関する相対質量増加を示すグラフである。この例からわかるように、耐高温性組成の形状記憶合金はタービン運転を代表する苛酷な酸化環境に耐え得る一方、低温動作用として当技術分野で知られているNiTi系形状記憶合金は激しく酸化されるために高温では有用でない。
