APPLICATIONS METAL MATRIX COiWPOSITES 5518383 MANUFACTURE 5518061 METHOD OF MODIFYING THE PROPERTIES OF A METAL MATRIX COMPOSITE BODY Newkirk Marc S; Urquhart Andrew; Aghajanian Michael K; Mortenson Mark; Ravi Vilupanur; Nagelberg Alan Newark, DE, UNITED STATES assigned to Lanxide Technology Company LP The present invention relates to modifying the properties of a metal matrix composite body by a post formation process treatment and/or a substantially contiguous modification treatment. The post formation process treatment may be apphcable to a variety of metal matrix composite bodies produced by various techniques, and is particularly applicable to modifying the properties of a metal matrix composite body produced by a spontaneous infiltration technique. The substantially contiguous modification process may also be used primarily in conjunction with metal matrix composite bodies produced according to a spontaneous infiltration technique. Particularly, at least a portion of the matrix metal of the metal matrix composite body and/or the filler material of the metal matrix composite body is modified or altered during and/or after the formation process.
5525374 METHOD FOR MAKING CERAMIC-METAL GRADIENT COMPOSITES Ritland Marcus A; Readey Dennis W; Sibold Jack; Rulis Dean Golden, CO, UNITED STATES assigned to Golden Technologies Company A process for fabricating ceramic-metal composites having ceramic and metal phases wherein the ceramic to metal ratio changes within the ceramic. The process includes the steps of contacting a porous ceramic matrix material with a molten metal whereby capillary action pulls the metal into the ceramic matrix to substantially fill the void space. The ceramic matrix has a porosity gradient wherein the infiltrated composite has a varying ratio of ceramic to metal.
REFLECTOR WITH METALLIC MATRIX COMPOSITE SUPPORT AND METHOD OF MANUFACTURING IT Abiven Henri Oinville, FRANCE assigned to Aerospatiale Societe Nationale Industrielle To manufacture a reflector formed by a reflective metallic layer on a metallic matrix composite support, a metallic layer having a reflective surface whose shape is at least approximately identical to the required geometrical shape is disposed on a mold surface having a geometrical shape complementary to the required geometrical shape of the reflector. Fibers to constitute the composite support are draped on the metallic layer. They are metallized by the metallic or intermetallic material to form the metallic matrix. This layer and the metallized fibers are subjected to temperature and pressure conditions adapted to press the reflective surface strongly against the mold surface and to cause diffusion welding of the layer with the metallized fibers and of the metallized fibers with themselves so as to integrate the layer to the composite support during consolidation of the latter.

OF FORMING ELECTRONIC PACKAGES
Keck Steven D; Rocazella Michael A; Engelgau Peter M; Hannon Gregory E; White Danny R; Nagelberg Alan S Hockessin, DE, UNITED STATES assigned to Lanxide Technology Company LP The present invention relates to the formation of a macrocomposite body for use as an electronic package or container. The macrocomposite body is formed by spontaneously infiltrating a permeable mass of filler material or a preform with molten matrix metal and bonding the spontaneously infiltrated material to at least one second material such as a ceramic or ceramic containing body or a metal or metal containing body. Moreover, prior to infiltration, the filler material or preform is placed into contact with at least a portion of a second material such that after infiltration of the filler material or preform by molten matrix metal, the infiltrated material is bonded to said second material, thereby forming a macrocomposite body. The macrocomposite body may then be coated by techniques according to the present invention to enhance its performance or bonding capabilities.
