Abstract
(57)【要約】
高温に晒されるタービンエンジンの超合金羽根用の熱障壁被覆体が開示される。この被覆体には、電子ビーム物理蒸着法によりアルミナイドあるいはMCrAlY結合被覆層に塗布されるセラミツク層が含まれる。セラミツク層は不安定化した孔を有する第1の部分と、第1の部分上に配置され安定化された孔を有する第2の部分と、孔に貴金属が被覆されている外側部分とを有する。安定化された孔の部分および貴金属被覆体により、セラミツク層の熱伝導率が減少される。孔を安定化することにより、高温での焼結圧縮が更に強く阻止され得る。

【発明の詳細な説明】
多孔質熱障壁被覆体
(技術分野)
本発明は超合金基板用の熱障壁被覆体、特にガスタービンエンジンの超合金羽
根に使用され低い熱伝導率を有する多層セラミツク熱障壁被覆体に関する。
(背景技術)
ガスタービンエンジン技術が進歩し、より高い効率のエンジンが必要とされる
に伴い、エンジン内のガス温度が高温化している。一方この高温での動作能力は
、衝突するガスの熱、酸化および腐食作用を受けるときの機械的な強度を維持す
る超合金タービン羽根の能力により制限される。この問題に対応する一方法は、
保護熱障壁被覆体を羽根に塗布して羽根を出来得る限り断熱し酸化あるいは高温
ガス腐食を防止することにあつた。
通常、結合被覆層およびセラミツク上層からなる熱障壁被覆体が超合金基板に
塗布される。セラミツク上層はプラズマ溶射法あるいは電子ビーム物理蒸着(E
B−PVD)法により塗布され得る。EB−PVD法を採用する場合、外側セラ

出願第06/603,811号には、アルミナイド層、アルミナ層および外側柱粒子セラミ
ツク層を含む超合金基板用の熱障壁被覆体が開示されている。
産業界で入手できるEB−PVD法により塗布されるセラミツク上層の欠点は
、セラミツク上層の熱伝導率がプラズマ溶射法により塗布されるセラミツク上層
の熱伝導率より約2倍高いことにある。高い熱伝導率は好ましくなく、これは内
部微細孔がほとんどなく柱粒子が比較的高い密度で蒸着されたことにより生じる
ものと考えられる。
従つてEB−PVD法により塗布され熱伝導率の低い熱障壁被覆およびその製
造法が求められている。
(発明の開示)
本発明の一目的はEB−PVD法により塗布され熱伝導率の低い熱障壁被覆体
を有する超合金製品を提供することにある。
本発明の他の目的はこのような被覆体を塗布する方法を提供することにある。
本発明によればこれらの目的は、アルミナイド結合被覆層と電子ビーム物理蒸
着法によりこの結合被覆層に塗布されるセラミツク層とを含む熱障壁被覆体を提
供することにより達成される。このセラミツク層は不安定孔を有する第1の部分
と、安定孔を有し第1の部分を覆う第2の部分と、孔が貴金属で被覆されている
外側部分とを有している。
この場合安定孔部分により、セラミツク層の熱伝導率が低
下され高温での焼結圧縮に対する抵抗が高くなる。且つ貴金属被覆層により、熱
伝導率がより低下され得る。
