摘要： Improvements in processing metal matrix composite materials by infiltration are disclosed. Specifically, a permeable mass comprising a preform or bedding material is provided to an infiltration setup in addition to that being the objective of the infiltration. The additional preform or bed is itself infiltrated at least at some point during processing to produce an additional, e.g., "sacrificial" MMC body. This sacrificial MMC reduces the amount that the carcass of matrix metal may shrink during cooling which in turn reduces the stress on and warping induced in the objective preform. The second or additional bed or preform is termed a "sacrificial" bed or sacrificial preform. The sacrificial bed or preform may be disposed between the object preform and the body of matrix metal, or opposite the body of matrix metal from the object preform, or both. The sacrificial MMC may be reused in subsequent infiltration setups to produce additional infiltrations of objective preforms. Further, a separation facilitator may be disposed between the objective preform and the sacrificial bedding/preform/MMC to assist in the recovery of the desired MMC body following infiltration and solidification of matrix metal.

摘要： Improvements in process metal matrix composite materials by infiltration are disclosed. Specifically, the effective contact area between a permeable mass or preform and a molten matrix metal (which is to infiltrate the permeable mass or preform) can be enlarged by coating one or more exterior surfaces of the permeable mass or preform to a desired extent with an infiltration enhancer or infiltration enhancer precursor. This technique is particularly useful for the infiltration of complex or irregularly shaped preforms. Further, it is frequently advantageous that the permeable mass or preform is not to be in direct contact with the body of molten matrix metal. The above concept can be extended to achieve this objective. Specifically, as long as there exists a pathway (33) comprising infiltration enhancer or infiltration enhancer precursor between the molten matrix metal (13) and the permeable mass or preform (11) to be infiltrated, infiltration of the permeable mass or preform can be achieved. More particularly, the molten matrix metal first infiltrates the pathway, following the pathway toward and into the permeable mass or preform.

摘要： New and improved automobile and light truck components are disclosed. Specifically, certain components traditionnally made from steel, sometimes hardened steel, such as cylinder liners, various valve train components, clutch discs, brake rotors and brake caliper pistons can now be made from aluminum based materials, thereby saving considerable weight. An aluminum/aluminum nitride metal matrix composite material is provided on the contacting or wear surfaces to provide adequate abrasion resistance, yet protect the engaging component from being excessively worn. The metal matrix composite layer can be applied to an aluminum based metal matrix composite substrate or to an unreinforced aluminum substrate. The A1/A1N surface is also easier to machine than most metal matrix composite materials.

摘要： 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.
