Abstract: The present invention relates to a novel method for forming metal matrix composite bodies, and the metal ma­trix composite bodies produced according to the novel method. Particularly, a permeable mass of filler material is formed into a preform by first forming a negative ca­vity (2) in a matrix metal (1) and thereafter placing said permeable mass of filler material (5) into said cavity (2). An infiltration enhancer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere are also in communication with the filler material (5), at least at some point along the process, which permit the matrix me­tal (1), when made molten, to spontaneously infiltrate the permeable mass of filler material (5), which at some point during the processing, may become self-supporting.

Abstract: A method is provided for producing a self-­supporting ceramic body comprising a polycrystalline ma­terial comprised of the oxidation reaction product of a parent metal (10) and having therein one or more channels which inversely replicate the geometry of a configured fugitive metal (6). The method includes providing an assembly of the configured fugitive metal (6) and the parent metal (10), optionally including a bed of per­meable filler (4), and heating the assembly to form a body of molten parent metal. The molten parent metal is oxidized under selected conditions to grow the polycry­stalline material to engulf the configured fugitive me­tal (6) (and to infiltrate the filler (4), if the filler (4) is present) and to cause the fugitive metal (6) to disperse into the engulfing polycrystalline material thereby leaving behind as the one or more channels the space formerly occupied by the configured fugitive me­tal (6). The method provides self-supporting ceramic bodies having therein one or more channels inversely replicating the shape of the configured fugitive metal (6).

Abstract: The disclosure concerns self-supporting ceramic structures, including ceramic composite structures embedding a filler, and methods of making them. The ceramic structures comprise a polycrystlline material made by oxidation of a body of molten parent metal with an oxidant. The poly­crystalline material has a first region substrate surmounted by a terminal region stratum which is integral with the first region. The terminal region stratum which is harder and of denser, finer crystalline structure than the first region substrate and is formed in a reaction stage subsequent to the reaction stage in which the first region of polycrystalline material is formed. Growth of the first stage is attained by by attenuating or interrupting the transport of molten parent metal to the first region under conditions which nonetheless leave or maintain therein enough oxidizable molten parent metal to form the polycrystalline material of the terminal region.

Abstract: The invention comprises a method of making self-supporting composite ceramic structures by the oxidation reaction of a body of molten parent metal precursor with a vapor-phase oxidant to form an oxidation reaction product. This reaction or growth is continued to form a thick, self-supporting ceramic body. The composite is recovered and in a separate subsequent operation, the surface is coated with one or more materials in order to effect desired changes in the properties of the surface, e.g., hardness, corrosion resistance.

Abstract: A heat storage medium comprising a body of parent metal and an intrinsically cohesive ceramic layer formed integrally with the metal body and encapsulating said metal body is produced by the directed oxidation of a body of parent metal outwardly from the surface of said body to form integrally with the body of parent metal a layer of oxidation reaction product which encapsulates unreacted parent metal and forms a cavity resulting from the depletion of parent metal.

Abstract: A ceramic-reinforced aluminum matrix composite is formed by contacting a molten aluminum-magnesium alloy with a permeable mass of ceramic material in the presence of a gas comprising from about 10 to 100% nitrogen, by volume, balance non-oxidizing gas, e.g., hydrogen or argon. Under these conditions, the molten alloy spontaneously infiltrates the ceramic mass under normal atmospheric pressures. A solid body of the alloy can be placed adjacent a permeable bedding of ceramic material, and brought to the molten state, preferably to at least about 700°C, in order to form the aluminum matrix composite by infiltration. In addition to magnesium, auxiliary alloying elements may be employed with aluminum. The resulting composite products may contain a discontinuous aluminum nitride phase in the aluminum matrix and/or an aluminum nitride external surface layer.

Abstract: A method of producing shaped, self-supporting ceramic bodies includes preparing a mold by applying a permeable, conformable material (5) to a shape-defining surface (3) of an expendable pattern (2). The permeable, conformable material, when set or stable, provides a mold with a shaped surface which is defined by, and is there­fore substantially congruent to, the shape-defining sur­face. Upon heating, the material of the expendable pattern (2) combusts or volatilizes and thus establishes the shaped cavity mold. A molten parent metal (1) is then vaporized with a vapor-phase oxidant in such a manner as to form a ceramic body which grows into the mold cavity, and is shaped by it. The ceramic body is recovered from the mold having a shaped surface replicating the shape-­defining surface (3) of the expendable pattern (2).

Abstract: A method is provided of producing a self-supporting ceramic composite structure having one or more encasement members (14), such as an encasing stell sleeve, joined to it by growth of the ceramic material to engagement surface(s) of the encasement member(s) (14). A parent metal is contacted with a body of filler (38) which is encased by the encasement mmber(s) (14). The resulting assembly is heated to melt and oxidize the parent metal, e.g., aluminum, to form a polycrystalline material comprising an oxidation reaction product which grows through the body of filler (38) and stops at the engagement surface(s) of the encasement member(s) (14) which thereby determines the surface geometry of the grown ceramic matrix. Upon cooling, the encasement member(s) (14) is shrinkfitted about the ceramic composite body. The invention also provides the resultant articles, for example, a ceramic composite body having a stainless steel member affixed thereto.
