Abstract
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.
Claims13
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.
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.
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.
