摘要： The present application provides slot seals for reducing leakages between adjacent components of turbomachinery. The seals may include a metallic shim and a coating overlying the metallic shim. The coating may be a metallic coating, a glass coating, an enamel coating or a ceramic coating. The coating may form an outer surface of the seal for engagement with seal slot surfaces of a seal slot of a turbomachine. The coating may be operable to conform to surface irregularities of the seal slot surfaces and remain coupled to the metallic shim at a predefined operating temperature and a predefined operating pressure to reduce leakage past the seal and thereby between the components. The coating may be configured to flow into depressions formed by the surface irregularities of the seal slot surfaces and remain coupled to the metallic shim at the predefined operating temperature and the predefined operating pressure.
摘要翻译： 本申请提供了槽密封件，用于减少涡轮机械的相邻部件之间的泄漏。 密封件可以包括金属垫片和覆盖金属垫片的涂层。 涂层可以是金属涂层，玻璃涂层，搪瓷涂层或陶瓷涂层。 涂层可以形成密封件的外表面，用于与涡轮机的密封槽的密封槽表面接合。 涂层可操作以符合密封槽表面的表面凹凸，并且在预定的操作温度和预定的操作压力下保持与金属垫片耦合，以减少经过密封件之间以及从而在组件之间的泄漏。 涂层可以被配置为流入由密封槽表面的表面不规则形成的凹陷中，并在预定义的操作温度和预定的操作压力下保持与金属垫片耦合。

摘要： Various embodiments include a gas turbine seal and methods of forming such seal. The method of forming the seal includes forming a freestanding ceramic seal for sealing in a gas turbine by applying a ceramic material on a substrate to form a ceramic layer, removing the substrate from the ceramic layer and finishing the ceramic layer to define the freestanding ceramic seal. The method includes depositing particles of the ceramic material in one of a molten or vapor state on a surface of the substrate and quenching the ceramic material to form the ceramic layer. The ceramic material comprises yttria-stabilized zirconia having a t′ tetragonal structure. A gas turbine including the freestanding ceramic seal is additionally disclosed.

摘要： A coated seal slot system for turbomachinery includes a first turbine component comprising a first groove having at least one first coating attached to at least a portion of the first groove of the first turbine component, a second turbine component comprising a second groove having at least one second coating attached to at least a portion of the second groove of the second turbine component. The first and the second turbine components are disposable adjacent to each other with the first groove having the first coating and the second groove having the second coating together forming a coated seal slot extending across a gap between the first turbine component and the second turbine component. A seal is disposable in the coated seal slot and extendable across the gap between the first and the second turbine components and engageable with the first coating and the second coating to inhibit leakage of gas through the gap.
