    Abstract: The present application provides methods and apparatus for processing ceramic fibers for the manufacture of ceramic matrix composites (CMCs). One method may include providing at least one frame including a planar array of unidirectional ceramic fibers extending across a void thereof. The method may further include depositing a coating on the ceramic fibers of the at least one frame via a chemical vapor deposition (CVD) process. The method may also include impregnating the coated ceramic fibers with a slurry including a ceramic matrix precursor composition to form at least one CMC prepreg, such as a prepreg tape. The ceramic fibers may be substantially SiC fibers, for example.

    Abstract: A method for manufacturing a fuel contacting component that facilitates reducing coke formation on at least one surface of the fuel contacting component is disclosed herein. The method includes applying a slurry composition including a powder including aluminum to the component surface, wherein the fuel contacting component is formed by an additive manufacturing process. The slurry composition is heat treated to diffuse the aluminum into the component surface. The heat treatment comprises forming a diffusion aluminide coating on the component surface, wherein the diffusion coating comprises a diffusion sublayer formed on the component surface and an additive sublayer formed on the diffusion sublayer. The method further comprises removing the additive sublayer of the diffusion aluminide coating with at least one aqueous solution such that the diffusion sublayer and the component surface are substantially unaffected, wherein the diffusion layer facilitates preventing coke formation on component surface.
