Claims
- 1. A composite comprising:
- a substrate having a carbon-rich surface, said carbon-rich surface having sufficient carbon to react with molybdenum to produce molybdenum carbide on said substrate, said substrate being selected from the group consisting of silicon carbide, boron carbide, alumina, silicon nitride, and aluminum nitride;
- a molybdenum carbide coating on said carbon-rich surface on said substrate; and
- a metal infiltrated into said substrate.
- 2. The composite defined in claim 1 wherein said coating of molybdenum carbide comprises a wetting agent for the infiltration of said carbonaceous material with metal.
- 3. The composite defined in claim 2 wherein said metal comprises metals and metal alloys selected from the group consisting of copper, aluminum, magnesium, iron, nickel, cobalt, titanium, silver, gold, platinum, rhodium, tin, and zinc and alloys of said copper, aluminum, magnesium, iron, nickel, cobalt, titanium, silver, gold, platinum, rhodium, tin, and zinc.
- 4. A composite having high thermal and electrical conductivity and a low coefficient of thermal expansion comprising:
- a substrate having a carbon-rich surface, said carbon-rich surface having sufficient carbon to react with molybdenum to produce molybdenum carbide on said substrate, said substrate being selected from the group consisting of silicon carbide, boron carbide, alumina, silicon nitrite, and aluminum nitride.
- a molybdenum carbide coating on said carbide-rich surface on said substrate; and
- a metal infiltrated into said substrate.
- 5. The composite defined in claim 4 wherein said metal is selected from the group consisting of copper, aluminum, magnesium, iron, nickel, cobalt, titanium, silver, gold, platinum, rhodium, tin, and zinc, and alloys of said metals.
