Abstract
Official abstract text for this publication.
A tool configured to dissolve in a selected subsurface environment includes a coating layer disposed about a particle core. The coating layer is formed from a plurality of substantially contiguous coated particles forming a substantially-continuous, cellular nanomatrix comprising a nanomatrix material.
First claim
Opening claim text (preview).
The invention claimed is: 1. A tool configured to dissolve in a selected subsurface environment comprising: a coating layer disposed about a particle core, the coating layer being formed from a plurality of substantially contiguous coated particles forming a substantially-continuous, cellular nanomatrix comprising a nanomatrix material, wherein the substantially continuous, cellular nanomatrix includes a thickness that is about two times a thickness of the coating layer. 2. The tool according to claim 1 , wherein the thickness of the substantially-continuous, cellular nanomatrix is substantially uniform. 3. The tool according to claim 2 , wherein the thickness of the substantially-continuous, cellular nanomatrix is between about 50 nm and about 5000 nm. 4. The tool according to claim 1 , wherein the substantially-continuous, cellular nanomatrix has a melting temperature (TM) and the particle core has a melting temperature (T DP ); wherein the coating layer is sinterable in a solid-state at a sintering temperature (Ts), and Ts is less than T M and TDP. 5. The tool according to claim 1 , wherein only the coating layer is dissolvable in the selected subterranean environment. 6. The tool according to claim 1 , wherein the tool is positioned to block fluid flow in the selected subterranean environment. 7. The tool according to claim 1 , wherein the substantially-continuous, cellular nanomatrix comprises a powder metal compact. 8. The tool according to claim 1 , wherein the coating layer is bonded to the particle core through interdiffusion. 9. The tool according to claim 1 , wherein the particle core is formed from the plurality of substantially contiguous coated particles forming a substantially-continuous, cellular nanomatrix comprising the nanomatrix material formed from adjacent particles sintered together through interdiffusion. 10. The tool according to claim 1 , wherein the particle core comprises a metal having a standard oxidation potential less than Zn. 11. The tool according to claim 1 , wherein the particle core comprises a non-metallic material comprising at least one of ceramics, glasses, and carbon. 12. A tool configured to dissolve in a selected subsurface environment comprising: a coating layer disposed about a particle core, the coating layer being formed from a plurality of substantially contiguous coated particles forming a substantially-continuous, cellular nanomatrix comprising a nanomatrix material, wherein the nanomatrix material comprises a cellular network of sintered metallic particles. 13. A tool configured to dissolve in a selected subsurface environment comprising: a coating layer disposed about a particle core, the coating layer being formed from a plurality of substantially contiguous coated particles forming a substantially-continuous, cellular nanomatrix comprising a nanomatrix material, wherein the nanomatrix material is formed from adjacent particles sintered together through interdiffusion.
