FUSED SAND-RESISTANT AERONAUTICAL PART
The invention relates to an aeronautical part, such as, for example, a turbine blade or a distributor vane, which is used in aeronautics, comprising at least one reactive layer adapted to react with at least one CMAS compound, the reactive layer at least partially covering the environmental barrier, characterized in that the material of the reactive layer comprises at least one oxide of the formula A'4-xA"xB'2-yB"yO11-delta, A' being selected from a rare earth, yttrium and scandium, A" being selected from a rare earth, yttrium, scandium and aluminum, B' being selected from tantalum and niobium, B" being selected from tantalum, niobium, titanium, zirconium, hafnium, aluminum and cesium, wherein x and y are real numbers between 0 and 2 and delta is a real number between -1 and 2 and preferably between -1 and 1.
本发明设计一种航空部件，该航空部件例如为用于航空学的涡轮叶片或分配器扇叶，该航空部件包括至少一种反应层，该至少一种反应层适合于与至少一种CMAS化合物反应，反应层至少部分地覆盖环境屏障，其特征在于，反应层的材料包括分子式为A’4‑xA”xB’2‑yB”yO11‑δ的至少一种氧化物，A’选自稀土、钇和钪，A”选自稀土、钇、钪和铝，B’选自钽和铌，B”选自钽、铌、钛、锆、铪、铝和铯，其中，x和y是介于0到2之间的实数，并且δ是介于‑1到2之间，优选地是介于‑1到1之间的实数。
