REFRACTORY COMPONENT WITH CERAMIC MATRIX COMPOSITE SKELETON

摘要

Aspects of the invention relate to a construction system and method for components in high temperature environments, such as the hot gas path components of a turbine engine. Such a component includes a skeleton (12) and a coating (14). The skeleton (12) is formed by a plurality of interconnected frame members (16), which give the component its general shape. The frame members (16) are made of ceramic matrix composite. A coating (14) is provided around at least a portion of the skeleton (12). The coating (14) is a refractory material, such as refractory ceramic. Examples of turbine engine components that can be constructed according to aspects of the invention are airfoils (10) with or without platforms (38), ring segments (66), combustor tiles and heat shields. A component according to aspects of the invention can be made using low cost fabrication and construction methods.
