Abstract
The invention provides a composite carbon or graphite having desirable properties such as corrosion and wear resistance. The invention combines a graphite substrate with a protective porous zone of silicon carbide. The whole body of graphite plus silicon carbide then is infiltrated with aluminum phosphate. An adhered barrier of silicon carbide, ranging in thickness between 0.015 and 0.050 inch thick is integrated with a graphite stratum to form a very hard surface, resistant to mechanical and chemical wear. The silicon carbide barrier is closely compatible to the graphite substrate, in resistance to thermal shock and in qualities of thermal expansion. In order to improve oxidation resistance further, a new composition was formed by infiltrating aluminum phosphate through the silicon carbide into the graphite to form a single body of composite graphite.
