    摘要: Coated particles comprise a core particle comprising a superhard material and having an average diameter of between 1 μm and 500 μm. A coating material is adhered to and covers at least a portion of an outer surface of the core particle, the coating material comprising an amine terminated group. A plurality of nanoparticles selected from the group consisting of carbon nanotubes, nanographite, nanographene, non-diamond carbon allotropes, surface modified nanodiamond, nanoscale particles of BeO, and nanoscale particles comprising a Group VIIIA element is adhered to the coating material.

    摘要: A powder metal composite is disclosed. The powder metal composite includes a substantially-continuous, cellular nanomatrix comprising a nanomatrix material. The composite also includes a plurality of dispersed first particles each comprising a first particle core material that comprises Mg, Al, Zn or Mn, or a combination thereof, dispersed in the nanomatrix; a plurality of dispersed second particles intermixed with the dispersed first particles, each comprising a second particle core material that comprises a carbon nanoparticle; and a solid-state bond layer extending throughout the nanomatrix between the dispersed first and second particles. The nanomatrix powder metal composites are uniquely lightweight, high-strength materials that also provide uniquely selectable and controllable corrosion properties, including very rapid corrosion rates, useful for making a wide variety of degradable or disposable articles, including various downhole tools and components.
