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.
Abstract translation: 描述了具有耐高温降解的涂层的制品以及制造这种制品的方法。 该制品包括设置在基底上的涂层。 涂层包括多个细长的表面连接的空隙。 该制品还包括设置在涂层的至少一些空隙内的保护剂; 保护剂包括能够与液体标称CMAS发生化学反应以在所述标称CMAS的结晶场外形成固体结晶产物的物质。 该固体结晶产物的熔融温度大于约1200摄氏度。 该方法通常包括以有效浓度将上述保护剂置于表面连接的空隙内,以基本上防止CMAS材料侵入到其中设置保护剂的空隙中。

Abstract: Embodiments of the present disclosure are directed to an article and methods of forming the article. The article includes a thermal barrier coating disposed on a substrate. The thermal barrier coating includes a thermal barrier material and partially filled surface-connected columnar voids. The partially filled surface-connected columnar voids are interspersed with the thermal barrier material in the thermal barrier coating. At least some of the partially filled surface-connected columnar voids include a calcium-magnesium-aluminum-silicon-oxide (CMAS)-reactive material disposed within, such that the CMAS-reactive material is physically separated from the substrate by a columnar cavity having an aspect ratio greater than 3.

Abstract: An article for service at high temperatures comprises a substrate comprising a first region and a second region; and a coating disposed over the substrate. The coating comprises a first portion disposed over the first region of the substrate and a second portion disposed over the second region of the substrate. The coating includes a layer comprising a ceramic material and further including a quantity of surface-connected voids, and a protective agent is disposed within at least some of the surface-connected voids of the layer. Within the first portion, the agent is present within the layer at a concentration of less than or equal to 4 percent by volume of the layer exclusive of the voids, while, within the second portion, the agent is present within the layer at a concentration up to the carrying capacity of the layer. Methods for forming the article are also presented.
