Abstract: Seal assemblies for reducing leakage between components of turbomachinery are provided. The seals may include a metallic shim, at least a pair of non-metallic end blocks, and ceramic fiber positioned between the shim and the end blocks. The shim may be mechanically coupled with the end blocks such that the metallic shim, non-metallic end blocks and ceramic fiber are coupled. The end blocks may be configured to account for misalignment of turbine components by ensuring sealing engagement of the seal to the components. The end blocks may be made from a ceramic or glass material, and the ceramic fiber may be a high temperature woven ceramic fiber. The ceramic fiber and/or the end blocks may protect the metallic shim from reaching potentially harmful temperatures during use of the seal, such as use in high temperature turbines including CMC components.

Abstract: The present application provides composite seals for reducing leakages between adjacent components of turbomachinery. The composite seals may include a metallic shim, a metallic support structure and a ceramic, glass or enamel coating. The shim and the support structure may be bonded or fused together. The support structure may include internal voids or gaps, and the coating may be applied to the shim and the support structure such that the coating is provided within the voids or gaps of the support structure, between portions of the support structure and the shim, and substantially over the outer surface of the support structure. The support structure may thereby provide a mechanical attachment between the shim and the coating. In use, the coating provides thermal and/or chemical insulation to the metallic shim and the support structure of the seal.

Abstract translation: 本申请提供了用于减少涡轮机械的相邻部件之间的泄漏的复合密封件。 复合密封件可以包括金属垫片，金属支撑结构和陶瓷，玻璃或搪瓷涂层。 垫片和支撑结构可以结合或熔合在一起。 支撑结构可以包括内部空隙或间隙，并且可以将涂层施加到垫片和支撑结构，使得涂层设置在支撑结构的空隙或间隙内，支撑结构的部分和垫片之间，以及 基本上在支撑结构的外表面上。 因此，支撑结构可以在垫片和涂层之间提供机械连接。 在使用中，涂层为金属垫片和密封件的支撑结构提供热和/或化学绝缘。
