    Abstract: A method for forming a high temperature coating includes applying carbon powder to a surface of a carbon/carbon (C/C) composite substrate to force the carbon powder into one or more surface voids of the surface of the C/C composite substrate. The carbon powder has a substantially same composition and morphology as a surface portion of the C/C composite substrate. The method includes applying a metal slurry to the surface of the C/C composite substrate following the application of the carbon powder and reacting a metal of the metal slurry with carbon of the carbon powder and carbon of the surface portion of the C/C composite substrate to form a metal-rich antioxidant layer of a metal carbide on the C/C composite substrate.

    Abstract: A method includes forming an article from a silicon-rich refractory mixture. The silicon-rich refractory mixture includes a silicon-rich silicon carbide preceramic polymer and a silicon carbide powder. The method includes heating the preform to pyrolyze the silicon-rich silicon carbide preceramic polymer and form a silicon-rich refractory material. The silicon-rich refractory material includes the silicon carbide powder and excess silicon in a silicon carbide matrix. The method further includes heating the silicon-rich refractory material to oxidize at least a portion of the excess silicon and form a reinforced refractory material. The reinforced refractory material includes a silicon dioxide phase at grain boundaries of the silicon carbide powder.

    Abstract: An assembly includes a first tube defining a first smooth, planar surface at an end of the first tube. The assembly includes a second tube defining a second smooth, planar surface at an end of the second tube. The assembly includes a force mechanism configured to apply a force to at least one of the first tube or the second tube to maintain contact between the first surface and the second surface. The first surface and the second surface are configured to interface to form a substantially hermetic seal when the assembly is cycled through a temperature cycle. The force is substantially normal to the first and second surfaces.
