Abstract
Official abstract text for this publication.
A method for producing a device having at least one internal feature includes manufacturing an internal volume of the internal features out of a first material, disposing the internal volume in a parent material that has a higher melting point than the first material, causing the internal volume to melt within the parent material, and allowing at least a portion of the first material to diffuse into the parent material, thereby leaving behind the at least one internal feature within the parent material.
First claim
Opening claim text (preview).
What is claimed is: 1. A flow device, comprising: a parent material defining a flow channel; and a channel material diffused into the parent material through a wall that defines the flow channel, wherein the channel material is only partially diffused into the parent material from the flow channel such that there is a portion of the parent material that includes the channel material and a portion of the parent material that does not include the channel material. 2. The flow device of claim 1 , wherein a diffusion gradient exists such that an amount of channel material becomes greater closer to the wall that defines the flow channel. 3. The flow device of claim 1 , wherein the flow device is a fuel nozzle and the flow channel is one or more fuel circuits. 4. The flow device of claim 1 , wherein the parent material includes at least one of a metal, metal alloy, a composite material, or a ceramic. 5. The flow device of claim 1 , wherein the channel material includes at least one of BNi-2, BNi-6, NB 30, NB 150, Bni-3, MBF-60, MBF-80, DF-3, Ni—Cr—B—Si, Haynes 230 doped with B, Al, Al+SiO 2 , B 2 O 3 , or Oxynitride glass. 6. The flow device of claim 5 , wherein the wall that defines the flow channel includes a mirror finish. 7. A flow device, comprising: a parent material defining a flow channel; and a channel material diffused into the parent material through a wall that defines the flow channel, wherein a diffusion gradient exists such that an amount of channel material becomes greater closer to the wall that defines the flow channel. 8. The flow device of claim 7 , wherein the flow device is a fuel nozzle and the flow channel is one or more fuel circuits. 9. The flow device of claim 7 , wherein the parent material includes at least one of a metal, metal alloy, a composite material, or a ceramic. 10. The flow device of claim 7 , wherein the channel material includes at least one of BNi-2, BNi-6, NB 30, NB 150, Bni-3, MBF-60, MBF-80, DF-3, Ni—Cr—B—Si, Haynes 230 doped with B, Al, Al+SiO 2 , B 2 O 3 , or Oxynitride glass. 11. A flow device, comprising: a parent material defining a flow channel; and a channel material diffused into the parent material through a wall that defines the flow channel, wherein the flow device is a fuel nozzle and the flow channel is one or more fuel circuits. 12. The flow device of claim 11 , wherein the parent material includes at least one of a metal, metal alloy, a composite material, or a ceramic. 13. The flow device of claim 11 , wherein the channel material includes at least one of BNi-2, BNi-6, NB 30, NB 150, Bni-3, MBF-60, MBF-80, DF-3, Ni—Cr—B—Si, Haynes 230 doped with B, Al, Al+SiO 2 , B 2 O 3 , or Oxynitride glass.
