摘要： A powder metal composite is disclosed. The powder metal composite includes a substantially-continuous, cellular nanomatrix comprising a nanomatrix material. The compact also includes a plurality of dispersed particles comprising a particle core material that comprises Mg, Al, Zn or Mn, or a combination thereof, dispersed in the nanomatrix, the core material of the dispersed particles comprising a plurality a plurality of distributed carbon nanoparticles, and a bond layer extending throughout the nanomatrix between the dispersed 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.

摘要： A composite includes a substrate, a binder layer disposed on a surface of the substrate; and a nanofiller layer comprising nanographene and disposed on a surface of the binder layer opposite the substrate. In addition, a nano-coating layer for coating a substrate includes multiple alternating layers of the binder layer and the nanofiller layer. Articles coated with the nano-coating layer prepared from alternating layers of nanofiller layer and binder layer have improved barrier properties, and may be used in down-hole applications.

摘要： A method of making a powder metal compact is disclosed. The method includes forming a coated metallic powder comprising a plurality of coated metallic powder particles having particle cores with nanoscale metallic coating layers disposed thereon, wherein the metallic coating layers have a chemical composition and the particle cores have a chemical composition that is different than the chemical composition of the metallic coating layers. The method also includes applying a predetermined temperature and a predetermined pressure to the coated powder particles sufficient to form a powder metal compact by solid-phase sintering of the nanoscale metallic coating layers of the plurality of coated powder particles to form a substantially-continuous, cellular nanomatrix of a nanomatrix material, a plurality of dispersed particles dispersed within the cellular nanomatrix and a solid-state bond layer extending throughout the cellular nanomatrix.

摘要： Se describen partículas desintegradoras que están diseñadas para ser mezcladas y bombeadas con materiales de soporte típicos, por ejemplo, arena, cerámicas, bauxita, etc., en las fracturas de una formación subterránea. Con el tiempo y/o cambio en las condiciones del sondeo o ambientales, estás partículas se desintegrarán ya sea parcial o completamente, en ejemplos no limitantes, mediante el contacto con un fluido para fracturación en el fondo del pozo, agua en formación o un fluido de estimulación tal como un ácido o salmuera. Una vez desintegrado, el paquete de soporte dentro de las fracturas conducirá a un mayor espacio abierto permitiendo una mayor conductividad y velocidades de flujo, las partículas desintegradoras se pueden producir al compactar y/o sinterizar partículas de polvo metálico, por ejemplo, magnesio u otro metal reactivo o sus aleaciones. Alternativamente, también se podrían diseñar partículas recubiertas con recubrimientos compactados y/o sinterizados de tamaño nanométrico y/o tamaño micrométrico donde los recubrimientos se desintegran más rápido o más lento que el núcleo en un entorno cambiado en el fondo del pozo.
