Abstract: A method for producing metal/ceramic composite materials includes an injection plunger; a casting chamber having an opening through which casting metal is poured in and a ceramic precursor product is shot in; and a die having a runner and a die cavity. A shot head is used to shoot ceramic powder into a die, so that the powder is compacted to form a porous preform. The preform is infiltrated with liquid metal under pressure in the die.

Abstract: Often, metal matrix composites (MMC's) lack adequate machinability and possess excessive abrasiveness because hard ceramic materials, such as silicon carbide, are used as the reinforcement phase. To make a metal matrix composite body having a more machinable and less abrasive surface, an MMC comprising an aluminum nitride reinforcement is formed on the surface of the body. In one embodiment, a layer is provided to a permeable mass or preform at the surface at issue, the layer featuring at least a reduced loading of ceramic filler material, and sometimes no ceramic material at all. The reduced loading is achieved by incorporating a fugitive material into the coating layer. Molten matrix metal is caused to infiltrate the permeable mass or preform and the coating layer to produce a macrocomposite body comprising a metal matrix composite coating and substrate. The metal matrix composite coating layer is distinguishable from the metal matrix composite substrate material, both compositionally and in terms of resulting properties. Under spontaneous infiltration conditions, as defined herein, aluminum nitride forms in-situ in the infiltrated body, including the surface layer. The present coating technique, however, permits a thicker MMC surface layer to be produced than could be produced previously. The present MMC surface layer can be applied to virtually any reinforced or unreinforced aluminum or aluminum alloy body.

Abstract translation: 通常，金属基复合材料（MMC）由于硬质陶瓷材料（如碳化硅）被用作增强相，因此缺乏足够的机械加工性并具有过度的磨损性。 为了制造具有更多可加工性和磨蚀性较差的表面的金属基质复合体，在本体的表面上形成包含氮化铝增强材料的MMC。 在一个实施方案中，在所讨论的表面上向可渗透质量块或预成型件提供一层，该层具有至少减少的陶瓷填料材料的载荷，并且有时根本不具有陶瓷材料。 减少的负荷是通过将一种短暂的材料掺入涂层来实现的。 使熔融基质金属渗入可渗透物质或预型体和涂层中以产生包含金属基质复合涂层和基底的大复合体。 金属基复合涂层与金属基复合基材材料的组成和结果特性无异。 在如本文所定义的自发渗透条件下，氮化铝在渗透体中原位形成，包括表面层。 然而，当前的涂覆技术允许生产比之前可以生产的更厚的MMC表面层。 本MMC表面层可以应用于几乎任何增强或未增强的铝或铝合金体。

Abstract: The specification and drawings describe and show an embodiment of and method of forming a liquid flow through heat exchanger structure cast in a metal matrix composite. The composite comprises a preform reinforcement material infiltrated with molten metal. The composite reinforcement material is injection molded around the heat exchanger structure allowing for intimate contact between the composite and structure. The composite formed has a specific coefficient of thermal expansion to match an active heat-generating device mounted thereon. The present invention allows for enhanced thermal and mechanical properties by eliminating voids or gaps at the composite to heat exchanger structure interface, these voids or gaps being present in prior art fabrication methods or induced by usage due to thermal cycling of prior art composites. It is emphasized that this abstract is provided to comply with the rules requiring an abstract, which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

Abstract: An apparatus for mixing particles in a liquid or semi-liquid medium, such as ceramic reinforcing particles in a molten metal or metal alloy matrix for the production of stir-cast metal matrix composite (MMC) materials. The particles can be introduced under the surface of the matrix by feeding the particles through the inner passage of a rotatable hollow impeller tube. The impeller tube is terminated at its lower end by an impeller head that includes teeth positioned proximate to an impeller base. The particles enter the matrix through a shear region in and around the volume between the impeller base and the impeller head. The rotating impeller and the high shear force thereby created wet the particles in the composite matrix and effect homogenization of the composite matrix. The present invention may be practiced either under vacuum or atmospheric pressure.

Abstract: An impermeable ceramic mold is disposed within a steel die and used in a process for pressure casting of elevated melting temperature alloys and pressure infiltration casting of elevated melting temperature alloys having wear resistant particles, included therewith. The ceramic mold provides an insulation layer between the molten metal and the steel die, and prevents welding between the molten metal and the die. The alloy steel die encloses the ceramic mold and provides the strength needed to resist the pressures generated during pressure infiltration casting.

Abstract: A free machining aluminum alloy contains an effective amount of one or more high melting point constituents that provide enhanced machining capability. The high melting point constituents occupy from about 0.1 to about 3.0 volume percent of the aluminum alloy. The constituents can be any material that is essentially insoluble in the aluminum alloy matrix so as to form a discontinuity and one that will resist deformation during machining to enhance the formation of voids between the matrix and the free machining constituents. The constituents include elements, nitrides, oxides, borides, carbides, silicides, aluminides and combinations thereof that have a high melting point and high strength and low solubility in aluminum at the elevated temperature so that the constituents resist deformation during the machining operation. The free machining aluminum alloy can be formed as a workpiece and subjected to any machining operation.
