International Classification:

B22D 1900

US Classification:

164 98

Abstract:

A process for forming pressure cast alumina tile reinforced aluminum alloy rmor in which a silver coated aluminum disc is first inserted into a mold assembly, the mold assembly includes a base plate, a hollow steel die with a removable steel liner located on the base plate, a plug disposed on the base plate within the die cavity, and a punch movably disposed within the die cavity, the aluminum disc being inserted within the die cavity over the plug. Next, an alumina tile preform is prepared by cutting a plurality of alumina tiles and weaving the tiles together with a stiff steel wire. The alumina tile preform is inserted over the silver coated aluminum disc in the cavity of mold assembly. The steel die, the plug and the disc are heated. The punch is also heated separately.

International Classification:

B22D 1914
B22D 2700

US Classification:

164 97

Abstract:

A predetermined quantity of a metal-matrix composite material is injected to a heating crucible along an angular infeed direction toward a location therein at which a vortex is formed by the blade of an agitator through which the material is stirred while being superheated above the melting temperature to a pouring temperature under which the melted material is transferred to a casting mold after surface skimming thereof to form a product having improved wear resistance properties.

Assignee:

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

B05D 302

US Classification:

427229

Abstract:

A reaction vessel comprising (1) a porous ceramic structure having intercecting, open pores and (2) silver metal coating the inner ceramic surfaces of the reaction vessel and filling the interconnecting, open pores to form a strong bond between the porous ceramic structure and the silver coating. The reaction vessel can be produced by (1) coating the inner surface and infiltrating the continuous, open pores of an unglazed porous ceramic structure (or vessel) with molten AgNO. sub. 3 ; (2) decomposing the AgNO. sub. 3 to silver metal; and then (3) repeating steps (1) and (2) until all the pores are filled with silver metal.

International Classification:

B05D 302

US Classification:

427217

Abstract:

Silver metal-coated boron carbide (B. sub. 4 C) particle reinforce aluminumthium alloy or magnesium-lithium matrix composites which are prepared by coating the B. sub. 4 C particles with molten AgNO. sub. 3, decomposing the molten AgNO. sub. 3 to form a coating of silver metal on the B. sub. 4 C particles, mixing the silver coated B. sub. 4 C particles into a molten aluminum-lithium alloy or magnesium-lithium alloy matrix, allowing the mixture to cool and solidify the solid composite.

International Classification:

H01L 3924

US Classification:

29599

Abstract:

A Nb-Ti or Nb-Zr low temperature superconducting (LTS) wire is coat with ten AgN0. sub. 3 which is then decomposed to form a uniform silver metal (Ag) coating on the LTS wire. A uniform coating of molten Al or Al alloy is formed on the Ag coated LTS wire and then solidified. A bundle of the coated LTS wires is inserted into an Al or Al alloy tube and cold worked to form a multifilamentary LTS cable comprising the Ag coated LTS wires each surrounded by an Al or Al alloy matrix.

B22D 1300

US Classification:

164100

Abstract:

Alumina tiles within aluminum framing jigs are fixedly positioned by lock ns within an internally coated mold for centrifugal casting within a block of an aluminum alloy material. Such jigs and the tiles framed therein are coated with silver before casting to prevent aluminum oxidation by heating of the aluminum material to a molten state for deposit into the mold. Bonding of the tiles and framing of the jigs with the aluminum material being cast is also enhanced by such silver coating.

International Classification:

C04B 3700

US Classification:

264 61

Abstract:

A process for producing a superconductor wire by: A. coating the inner surface of a steel tube with a thin layer of silver metal; B. packing the tube with high temperature superconductor ceramic (HTSC) powder; C. sealing the tube; D. cold working the tube to reduce its diameter; E. etching or dissolving away the steel tube to leave a superconductor wire comprising the silver metal coating that was on the inner surface of the steel tube as a thin silver metal sheath which encapsulates the HTSC powder. The superconductor wire can be further treated by sintering or oxygenating the HTSC powder.
