Abstract

A method and apparatus for providing molten metal infiltration into a component is provided.

Claims (31)

1. A wick attachment comprising:

a wick;

a component; and

a weld material;

wherein the wick and the component are attached together using the weld material that is selected from the group of materials consisting of Si/Zr, Si, Zr/Si, ZrB 2 and TiB 2 , wherein the weld material has a first melting point and the wick is for fluidly communicating an infiltrant haying a second melting point to the component, and wherein the first melting point of the weld material is higher than the second melting point of the infiltrant.

2. The wick attachment of claim 1 further comprising an infiltrant source, wherein the wick is in fluid communication with the infiltrant source and the component, the component comprising a ceramic matrix composite.

3. The wick attachment of claim 1 wherein the attachment comprises a spot weld.

4. The wick attachment of claim 1 wherein the attachment comprises a continuous weld.

5. The wick attachment of claim 1 wherein multiple attachments are used.

6. The wick attachment of claim 1 further comprising multiple wicks.

7. The wick attachment of claim 1 further comprising an infiltrant source adapted to receive the infiltrant, wherein the wick is in fluid communication with the infiltrant source and the component and wherein the infiltrant is selected from the group of materials consisting of silicon, Si/C/B, Zr/Si, Zr and Ti/6Al/4V.

8. The wick attachment of claim 1 further comprising an infiltrant source adapted to receive the infiltrant, wherein the wick is in fluid communication with the infiltrant source and the component and wherein the infiltrant is selected from the group of materials consisting of silicon, and Si/C/B.

9. The wick attachment of claim 1 further comprising an infiltrant source adapted to receive the infiltrant, wherein the wick is in fluid communication with the infiltrant source and the component and wherein the infiltrant comprises silicon.

10. A method of infiltrating a material into a component, the method comprising the steps of

providing a wick;

providing a component;

coupling together the component and the wick in fluid communication with one another, wherein the wick and the component are attached together using a weld material that is selected from the group of materials consisting of Si/Zr, Si, Zr/Si, ZrB 2 and TiB 2 , wherein the weld material has a first melting point and the wick is for fluidly communicating an infiltrant having a second melting point to the component, and wherein the first melting point of the weld material is higher than the second melting point of the infiltrant.

11. The method of claim 10 further comprising the step of providing an infiltrant source having the infiltrant contained therein, the wick and the infiltrant being in fluid communication with one another, and wherein the coupling step comprises welding together the wick and the component, the component comprising a ceramic matrix composite.

12. The method of claim 11 wherein the welding step comprises accomplishing the process selected from the group consisting of Gas Tungsten Arc Welding, Tungsten Inert Gas, Gas Metal Arc Welding, Metal Inert Gas, resistance welding, laser welding, e-beam welding, local metal casting or a range of plasma spray and cold metal spray processes.

13. A wick attachment comprising:

a wick;

a component; and

a weld material;

wherein the wick and the component are attached together using the weld material that is selected from the group of materials consisting of Si/Zr, Si, and Zr/Si, wherein the weld material has a first melting point and the wick is for fluidly communicating an infiltrant having a second melting point to the component, and wherein the first melting point of the weld material is higher than the second melting point of the infiltrant.

14. The wick attachment of claim 13 further comprising an infiltrant source adapted to receive the infiltrant, wherein the wick is in fluid communication with the infiltrant source and the component and wherein the infiltrant is selected from the group of materials consisting of silicon, and Si/C/B.

15. The wick attachment of claim 13 further comprising an infiltrant source adapted to receive the infiltrant, wherein the wick is in fluid communication with the infiltrant source and the component and wherein the infiltrant comprises silicon.

16. The wick attachment of claim 13 further comprising an infiltrant source, wherein the wick is in fluid communication with the infiltrant source and the component, the component comprising a ceramic matrix composite.

17. The wick attachment of claim 13 wherein the attachment comprises a spot weld.

18. The wick attachment of claim 13 wherein the attachment comprises a continuous weld.

19. The wick attachment of claim 13 wherein multiple attachments are used.

20. The wick attachment of claim 13 further comprising multiple wicks.
