Title:
NANOMATRIX METAL COMPOSITE
Document Type and Number:
WIPO Patent Application WO/2012/015567
Kind Code:
A3
Abstract:
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, A1, 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.
