Definitions

  • the second powder 30 includes a plurality of second powder particles 32. These second powder particles 32 may be selected to change a physical, chemical, mechanical or other property of a powder particle compact 200 formed from powder 10 and second powder 30, or a combination of such properties. In an exemplary embodiment, the property change may include an increase in the compressive strength of powder compact 200 formed from powder 10 and second powder 30. In another exemplary embodiment, the second powder 30 may be selected to promote the selective and controllable dissolution of in particle compact 200 formed from powder 10 and second powder 30 in response to a change in a property of the wellbore, including the wellbore fluid, as described herein. Second powder particles 32 may be uncoated or coated with a metallic coating layer 36.
  • the reactive fluid including carrier fluid, causes at least a portion of the plurality of particle cores 14 to be suspended in the fluid, thereby enabling the entire surface of the suspended particle cores 14 to be exposed to the reactive fluid, including, for example, a desired organometallic constituent, and enabling deposition of metallic coating material 20 and coating layer 16 over the entire surfaces of particle cores 14 such that they each become enclosed forming coated particles 12 having metallic coating layers 16, as described herein.
  • each metallic coating layer 16 may include a plurality of coating layers.
  • dispersed particles 214 are formed from particle cores 14 dispersed in the cellular nanomatrix 216 of sintered metallic coating layers 16, and the nanomatrix 216 includes a solid-state metallurgical bond 217 or bond layer 219, as illustrated schematically in FIG. 10, extending between the dispersed particles 214 throughout the cellular nanomatrix 216 that is formed at a sintering temperature (T s ), where T s is less than T c and T P .
  • T s sintering temperature
  • dispersed particles 214 and particle core materials 218 are formed in conjunction with nanomatrix 216, diffusion of constituents of metallic coating layers 16 into the particle cores 14 is also possible, which may result in changes in the chemical composition or phase distribution, or both, of particle cores 14.
  • dispersed particles 214 and particle core materials 218 may have a melting temperature (TDP) that is different than Tp.
  • TDP includes the lowest temperature at which incipient melting or liquation or other forms of partial melting will occur within dispersed particles 214, regardless of whether particle core material 218 comprise a pure metal, an alloy with multiple phases each having different melting temperatures or a composite, or otherwise.
  • Powder compact 200 is formed at a sintering temperature (T s ), where T s is less than T C ,T P ,
  • Method 400 includes forming 410 a coated metallic powder 10 comprising powder particles 12 having particle cores 14 with nanoscale metallic coating layers 16 disposed thereon, wherein the metallic coating layers 16 have a chemical composition and the particle cores 14 have a chemical composition that is different than the chemical composition of the metallic coating material 16.
  • predetermined hold times of about 1 to about 5 hours may be used.
  • the predetermined sintering temperature, T s will preferably be selected as described herein to avoid melting of either particle cores 14 and metallic coating layers 16 as they are transformed during method 400 to provide dispersed particles 214 and nanomatrix 216.
  • dynamic forging may include application of a forging pressure, such as by dynamic pressing to a maximum of about 80 ksi at pressure ramp rate of about 0.5 to about 2 ksi/second.
