Abstract: Systems and methods for infiltrating porous ceramic matrix composite (CMC) preforms to form CMC articles are disclosed. One method may include positioning the porous CMC preform in an opening of a die set for an infiltration system, and flowing a molten densifier over the porous CMC preform in a first flow direction to infiltrate a plurality of voids formed between each of a plurality of ply stacks of the CMC preform. The method may also include flowing the molten densifier over the porous CMC preform in a second flow direction, distinct from the first flow direction, to infiltrate the plurality of voids formed between each of the plurality of ply stacks of the CMC preform. The second flow direction may be substantially parallel to a predetermined, unidirectional material orientation of at least one ply stack of the plurality of ply stacks of the CMC preform.

Abstract: A method includes masking at least one hole of an article with a paste, wherein the hole opens onto a surface of the article, applying a coating to the surface of the article, and removing the paste including contacting the paste with water, leaving at least one open hole in the surface of the coated article. The paste includes about 40-80 wt % of a filler material, about 0.5-20 wt % of an inorganic binder, about 0.5-15 wt % of a polyhydroxy compound and about 5-25 wt % of water. The filler material includes a first material which includes alkali metal doped alumina, zirconium oxide, titanium oxide, silicon dioxide, or a combination thereof and a second material which includes a silicate. A weight ratio between the first and second materials is in a range of about 1-10.

Abstract: A method for protecting a coating on a surface of a component is provided. The method includes a coating step for coating at least a portion of the component with a ceramic slurry. A projecting step is used for projecting a pattern of light onto the component with a lithographic process to expose and solidify a ceramic layer. A removing step is used for removing unexposed portions of the ceramic slurry from the component. A heating step heats the component to sinter the ceramic layer. The ceramic layer is formed with multiple fracture planes.

Abstract: A mold assembly for use in forming a component having an internal passage defined therein includes a mold defining a mold cavity therein, and a jacketed core positioned with respect to the mold. The jacketed core includes a hollow structure, and an inner core disposed within the hollow structure and positioned to define the internal passage within the component when a component material in a molten state is introduced into the mold cavity and cooled to form the component. The jacketed core also includes a first coating layer disposed between the hollow structure and the inner core.

Abstract: A method for forming a CMC article is disclosed, including forming a CMC precursor ply assembly. Forming the CMC precursor ply assembly includes laying up a plurality of CMC precursor plies and entraining a melt infiltration agent to form an entrained agent supply. Each of the plurality of CMC precursor plies includes a matrix precursor and a plurality of ceramic fibers. The plurality of CMC precursor plies and the entrained agent supply are arranged to form the CMC precursor ply assembly, which includes an article conformation. The method further includes carbonizing the CMC precursor ply assembly, infusing the melt infiltration agent from the entrained agent supply into the plurality of CMC precursor plies, and densifying the CMC precursor ply assembly with the melt infiltration agent to form the CMC article.
