PROBLEM TO BE SOLVED: To provide a method for manufacturing a CMC turbine engine component having an interface layer on a CMC to improve load distribution within the CMC and reduce metallic wear. SOLUTION: A ductile interface is provided in an attachment location to which a metallic surface is adjacent, by an integral layer provided with a main body comprising a ceramic matrix material, including the attachment location and constituted so as to be adjacent to a second component while being exposed in high-temperature environment and with the interface layer (38) which defines at least part of the surface of the attachment location, has a matrix side face (42) and outside face (40) and is inserted into a space between the main body and the second component while being exposed in the high-temperature environment, and of which matrix side face (42) is coupled to the main body by metallurgical technology. This ductile layer provides favorable load distribution from the attachment location to inside of the composite, and eliminates the need for a metallic shim. COPYRIGHT: (C)2006,JPO&NCIPI |
