Abstract: Articles, such as components for high temperature turbomachinery components, include one or more coatings bearing certain perovskite compositions resistant to incursion by liquid calcium-magnesium-aluminum-silicon-oxide (CMAS) materials during service. The CMAS-reactive material includes a perovskite-structured oxide, which comprises a) a rare earth element, b) niobium, tantalum or a combination of tantalum and niobium, and c) oxygen. The CMAS-reactive material is present in an effective amount to react with a CMAS composition at an operating temperature, thereby forming a reaction product having one or both of melting temperature and viscosity greater than that of the CMAS composition.

Abstract: An article including a substrate and a plurality of coatings disposed on the substrate is presented. The plurality of coatings includes a thermal barrier coating disposed on the substrate; and a protective coating including a calcium-magnesium-aluminum-silicon-oxide (CMAS)-reactive material disposed on the thermal barrier coating. The CMAS-reactive material has an orthorhombic weberite crystal structure. The CMAS-reactive material is present in the plurality of coatings in an effective amount to react with a CMAS composition at an operating temperature of the thermal barrier coating, thereby forming a reaction product having one or both of melting temperature and viscosity greater than that of the CMAS composition. A method of making the article and a related turbine engine component are also presented.
Abstract translation: 提出了一种包括基板和设置在基板上的多个涂层的制品。 多个涂层包括设置在基板上的热障涂层; 以及包括设置在热障涂层上的钙镁 - 铝 - 氧化硅（CMAS）反应材料的保护涂层。 CMAS反应性材料具有斜方晶系的Weberite晶体结构。 CMAS反应性材料以有效量存在于多个涂层中，以在热障涂层的操作温度下与CMAS组合物反应，从而形成具有大于或等于 CMAS组成。 还提出了制造物品和相关涡轮发动机部件的方法。

Abstract: Articles having coatings that are resistant to high temperature degradation are described, along with methods for making such articles. The article comprises a coating disposed on a substrate. The coating comprises a plurality of elongated surface-connected voids. The article further includes a protective agent disposed within at least some of the voids of the coating; the protective agent comprises a substance capable of chemically reacting with liquid nominal CMAS to form a solid crystalline product outside the crystallization field of said nominal CMAS. This solid crystalline product has a melting temperature greater than about 1200 degrees Celsius. The method generally includes disposing the protective agent noted above within the surface connected voids of the coating at an effective concentration to substantially prevent incursion of CMAS materials into the voids in which the protective agent is disposed.
