    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: Described is a process for producing sintered parts from an aluminum sintering mixture, wherein between 10 and 70% by weight of pure aluminum powder and between 30 and 90% by weight of an aluminum alloy powder are mixed to form an aluminum sintering mixture. The aluminum alloy powder is of the following composition: between 14 and 35% by weight of Si; between 1 and 7% by weight of Cu; between 0.3 and 2.5% by weight of Mg; between 0.3 and 6% by weight of a transition metal, the balance aluminum. The pure alloy powder and the aluminum alloy powder are each of a grain size of a maximum of 315 &mgr;m. The aluminum sintering mixture is mixed with between 0.5 and 2% by weight of compacting additive. The mix of alloy sintering mixture and compacting additive is compacted to form a green compact. The green compact is then sintered. As no low-melting phases occur in the invention, sintered bodies which are stable in respect of shape are reproducibly obtained in the sintering operation.
