技术领域 TECHNICAL FIELD
本发明大体涉及涡轮。  The present invention relates generally to a turbine. 更具体地，涉及陶瓷基质复合物(CMC)构件和将金属密封件附接至陶瓷基质复合物构件的方法。 More specifically, attached to the ceramic matrix composite member relates to a method of a ceramic matrix composite (CMC) and a metal seal member.
背景技术 Background technique
曾经已经使用许多技术来制造涡轮发动机构件，例如使用陶瓷基质复合物(CMC)的涡轮叶片或喷嘴。  Many techniques have been used to manufacture turbine engine components, e.g., a ceramic matrix composite (CMC) turbine blade or nozzle. 制造CMC构件的一种方法涉及包含纤维性材料的碳化硅基质复合物的生产，该纤维性材料渗透有熔化的硅，在本文中指(Silcomp)加工。 A method of manufacturing CMC producing member comprising a fibrous material relates to silicon carbide matrix composite, the fibrous material is impregnated with molten silicon, we refer herein (Silcomp) processing. 该纤维通常具有大约140微米或更大的直径，这防止了难理解的、复杂的形状，例如将通过(Silcomp)加工制造的涡轮叶片构件。 The fibers typically have about 140 microns or larger in diameter, which prevents difficult to understand, complex shapes, such as a turbine blade member through (Silcomp) processing and manufacturing.
制造CMC涡轮叶片的另一种技术是公知为浆体铸型熔化浸渗法(MI)加工的方法。  Another technique of manufacturing CMC turbine blades is known as the slurry cast melt infiltration method (MI) Processing Method. 在使用浆体铸入MI方法制造的一种方法中，通过首先提供均衡的二维(2D)织布的折叠来产生CMC，该织布包括包含碳化硅(SiC)的纤维，具有彼此成基本90角的两个编织方向，带有在编织的两个方向上延伸的基本相同数量的纤维。 In one method, a method using a slurry cast into MI manufactured by first providing a balanced two-dimensional (2D) woven fabric folded to produce CMC, including the woven fibers comprising silicon carbide (SiC), with each other substantially two knitting direction angle 90 with substantially the same number of fibers woven in two directions extending.
通常，这种涡轮构件要求邻近的金属硬件和/或金属表面的附接。  Typically, such a turbine requires member attached adjacent metal hardware and / or metal surfaces. 与将CMC附接至金属硬件相关的两个缺点为:硬研磨性陶瓷材料表面对金属硬件的磨损;和负载在CMC中的分布不足。 Two disadvantages associated with the CMC is attached to the metal hardware related to: hard abrasive surface of the ceramic material wear and tear on the metal hardware; and inadequate distribution of load in the CMC. 负载分布在CMC构件和金属表面(例如罩)之间的界面中是关键的。 Interface load distributing member in the CMC and metal surfaces (e.g., mask) between critical. 典型地，已经将金属垫片或陶瓷布插入在CMC和金属表面之间以改进负载分布。 Typically, it has been the metal gasket or ceramic cloth inserted between the CMC and metal surfaces for improved load distribution. 通过涂层向金属硬件或涂层向喷嘴附接表面的应用，使磨损典型地降低。 By coating the metal hardware or coatings applied to the surface of the nozzle attachment, the wear typically decrease.
因此，在本领域中所希望的是，不遭受上述缺点的陶瓷基质复合物(CMC)构件和将金属密封件附接至CMC构件的方法。  Thus, in the art it is desirable that the attachment member to the CMC method does not suffer from the above drawbacks of the ceramic matrix composite (CMC) and a metal seal member.
