ABSTRACT:
A composite structural ceramic article and method of fabrication thereof. The article of the invention is specifically designed for use in high temperature, corrosive and erosive environments such as those found in heat engines, heat exchangers, stationary power equipments and industrial process equipments. The article comprises a porous carbon fibrous substrate or other suitable high temperature fibrous substrate which may include: a pyrolytic carbon or appropriate chemical vapor deposited sheath formed about each fiber of the substrate; a chemically vapor deposited metallic carbide, oxide, boride or nitride coating over the coated fibers of the substrate; and an impermeable metallic carbide, oxide, boride or nitride outer protective layer formed about the entire periphery of the coated substrate. In accordance with the method of the invention, the metallic coating is applied to the fibers in such a manner such that internal porosity of the article is precisely controlled and a flaw resistant, tough, non-catastrophic failing structural ceramic body is formed.
