    Abstract: A method of making a ceramic composite component includes providing a fibrous preform or a plurality of fibers, providing a first plurality of particles, coating the first plurality of particles with a coating to produce a first plurality of coated particles, delivering the first plurality of coated particles to the fibrous preform or to an outer surface of the plurality of fibers, and converting the first plurality of coated particles into refractory compounds. The first plurality of particles or the coating comprises a refractory metal.

    Abstract: A ceramic article includes a ceramic matrix composite that has a porous reinforcement structure and a ceramic matrix within pores of the porous reinforcement structure. The ceramic matrix composite includes a surface zone comprised of an exterior surface of the ceramic matrix composite and pores that extend from the exterior surface into the ceramic matrix composite. A glaze material seals the surface zone within the pores of the surface zone and on the exterior surface of the surface zone as an exterior glaze layer on the ceramic matrix composite. The glaze material is a glass or glass-ceramic material. The ceramic matrix composite includes an interior zone under the surface zone, and the interior zone is free of any of the glaze material and has a greater porosity than the surface zone.

    Abstract: A method for atomic layer deposition of high temperature materials from single source precursors includes placing a substrate in a reaction zone in gas isolation from other reaction zones and contacting the substrate in the reaction zone with a reactant to allow atoms in the reactant to combine with reaction sites on the substrate to form a layer of the reactant on the substrate. The substrate is then placed in a purge zone and purged with a flowing inert gas. The substrate is then placed in a final reaction zone in gas isolation from the other zones wherein the final reaction zone has an atmosphere and temperature to decompose adsorbed reactant and/or form desired phases with crystallinity to form a layer of material. The substrate is then placed in a purge zone and the process is repeated until a layer of material of desired thickness is formed on the substrate.
