Refractory Material with Supercritical Fluid-Deposited Interface Coatings

A ceramic matrix composite, comprising:

• a refractory material, including:
• a plurality of refractory filaments assembled together in the form of a broadgood,
• an interface coating applied to the plurality of refractory filaments, wherein the interface coating includes a refractory metal or semi-metal oxide, metal or semi-metal nitride, metal or semi-metal carbide, metal or semi-metal oxynitride, metal or semi-metal carbonitride, metal or semi metal oxycarbide, or a combination thereof formed by depositing an organometallic precursor onto the refractory filament by supercritical fluid deposition, and heat treating the organometallic precursor in the presence of an atmospheric condition so that the organometallic precursor becomes oxidized, pyrolyzed, or carbidized forming an interface coating that surrounds a surface of the refractory filament;
• and
• a ceramic material composited with and encapsulating at least a portion of the broadgood.
