Abstract

A method of manufacturing a multi-material tubular structure includes spinning a can, depositing a powdered material into the can and compacting the powdered material within the can to provide a tubular structure.

First claim

What is claimed is:

1 . A method of manufacturing a multi-material tubular structure comprising:
spinning a can; depositing a powdered material into the can; and compacting the powdered material within the can to provide a tubular structure.

2 . The method according to claim 1 , wherein the can is spun to forces of greater than 1G.

3 . The method according to claim 1 , wherein the can is cylindrical in shape.

4 . The method according to claim 1 , wherein the depositing step includes the can and a powder injector moving relative to one another during powder deposition.

5 . The method according to claim 1 , wherein the powdered material is an atomized metal.

6 . The method according to claim 1 , wherein the compacting step includes vibrating the can during spinning step.

7 . The method according to claim 6 , wherein the can is mechanically vibrated.

8 . The method according to claim 6 , wherein the can is acoustically vibrated.

9 . The method according to claim 1 , comprising the step of scraping a layer of powdered material in the can to provide a desired wall thickness.

10 . The method according to claim 1 , comprising inspecting the characteristics of the layer.

11 . The method according to claim 1 , comprising the step of depositing a powdered metal into an inner cavity of the tubular structure to form a cylindrical structure having a solid cross-section.

12 . The method according to claim 11 , comprising the step of compacting the tubular structure to provide a billet.

13 . The method according to claim 12 , comprising the step of cutting a compacted billet to a desired length.

14 . The method according to claim 12 , comprising the step of forging the billet.

15 . The method according to claim 1 , comprising the step of depositing multiple layers of powdered material.

16 . The method according to claim 15 , wherein the multiple layers include a different material than one another.

17 . The method according to claim 1 , comprising the step of packing a first layer before depositing a second layer.

18 . The method according to claim 1 , comprising the step of providing an inner form within the can.

19 . The method according to claim 18 , comprising the step of providing a vacuum on the inner form.

20 . The method according to claim 1 , comprising the step of heating the powdered material.
