    • The method of the present invention utilizes high pressure, near-supercritical CO2 within a pressure vessel to process filamentary nanocarbon to debulk, disperse, purify, surface treat, pre-impregnate, and micronize the carbon nanofibers. In accordance with the invention, near-supercritical CO2 is utilized within a pressure vessel to effect the desired process upon filamentary nanocarbon. For example, a quantity of filamentary nanocarbon can be effectively debulked, de-agglomerated and disentangled by agitating the mixture within the pressure vessel. When the CO2 is released from the pressure vessel, the filamentary nanocarbon exhibits a dramatic reduction in volume. Other nanofiber processes can be performed such as surface treating and pre-impregnation by introduction of the desirable species into the near-supercritical CO2 prior to processing. Purification processing can additionally be performed by introducing a co-solvent into the near-supercritical CO2.
    • 本发明的方法利用压力容器内的高压,近超临界CO 2来处理丝状纳米碳以减少,分散,净化,表面处理,预先浸渍和微粉化碳纳米纤维。 根据本发明,在压力容器内使用近超临界CO 2以在丝状纳米碳上实现所需的方法。 例如,通过搅动压力容器内的混合物,一定量的丝状纳米碳可以被有效地减粘,去结块和解开。 当二氧化碳从压力容器释放时,丝状纳米碳体积显着减少。 可以在处理之前通过将所需物质引入近超临界CO 2来进行其它纳米纤维工艺,例如表面处理和预浸渍。 净化处理可另外通过将辅助溶剂引入近超临界CO 2来进行。

    • Novel processes for fabricating metal matrix composites consisting of discontinuous reinforcing particles in a metal matrix are described. In one aspect, reinforcing particles are coated with a metal matrix material by means of chemical vapor deposition using a volatile metal-containing compound, followed by consolidation of the metal-coated particles. In another aspect, reinforcing particles are coated with a metal matrix material by means of electrochemical deposition of a metal, followed by consolidation of the metal-coated particles. In yet another aspect, reinforcing particles coated with a metal matrix material by one of the aforesaid methods are blended with metal or alloy particles not containing such reinforcement, then consolidated.
    • 描述了在金属基质中制造由不连续增强颗粒组成的金属基复合材料的新方法。 在一个方面,通过使用含挥发性金属的化合物进行化学气相沉积,然后将金属包覆的颗粒固结,用金属基质材料涂覆增强颗粒。 另一方面,通过金属的电化学沉积,然后将金属包覆的颗粒固结,用金属基体材料涂覆增强颗粒。 在另一方面,通过上述方法之一用金属基质材料涂覆的增强颗粒与不含这种增强剂的金属或合金颗粒混合,然后固化。
