Abstract

In one example, a method including depositing an antioxidant material on a first surface region of a carbon-carbon composite substrate via a print head of a three-dimensional printing device to form a first layer of the antioxidant material on the first surface region of the substrate, and depositing the antioxidant material on a second surface region of the substrate via the print head of the three-dimensional printing device to form a second layer of the antioxidant material on the second surface region. The method may be, for example, a method for forming a carbon-carbon composite component including an antioxidant coating, the antioxidant coating including the first layer and second layer of the antioxidant material.

First claim

What is claimed is:

1 . A method for forming a carbon-carbon composite component including an antioxidant coating, the method comprising:
depositing an antioxidant material on a first surface region of a carbon-carbon composite substrate via a print head of a three-dimensional printing device to form a first layer of the antioxidant material on the first surface region of the substrate; and depositing the antioxidant material on a second surface region of the substrate via the print head of the three-dimensional printing device to form a second layer of the antioxidant material on the second surface region, wherein the antioxidant coating includes the first layer and second layer of the antioxidant material.

2 . The method of claim 1 , wherein the first layer comprises a penetrant type layer of antioxidant material.

3 . The method of claim 1 , wherein the first layer comprises a barrier type layer of antioxidant material

4 . The method of claim 1 , wherein the antioxidant material comprises at least one of a phosphorus based antioxidation compound or ceramic precursor compound.

5 . The method of claim 1 , wherein at least a portion of the second layer overlaps a portion of the first layer.

6 . The method of claim 1 , wherein the antioxidant coating includes a plurality of individual layers of the antioxidant material, including the first layer and second layer, defining an overall thickness of the antioxidant coating of approximately 2 microns to approximately 30 microns.

7 . The method of claim 1 , wherein the first layer and the second layer each define a thickness between approximately one micron and approximately 10 microns.

8 . The method of claim 1 , further comprising leaving a third surface region of the substrate not covered with antioxidant material, wherein the first surface region and the second surface regions of the substrate comprise non-friction surface regions of the substrate, and the third surface region of the substrate comprises a friction surface of the substrate.

9 . The method of claim 1 , wherein the carbon-carbon composite material exhibits a density greater than or equal to approximately 1.7 grams per cubic centimeter.

10 . The method of claim 1 , further comprising densifying a carbonized carbon fiber preform to form the carbon-carbon composite material prior to depositing the antioxidant material.

11 . A system comprising:
a three-dimensional print head configured to deposit an antioxidant material on a carbon-carbon composite component to form an antioxidant coating; and a controller configured to control the print head to deposit the antioxidant material on a first surface region of the carbon-carbon composite substrate to form a first layer of the antioxidant material on the first surface region of the substrate, and control the print head to deposit the antioxidant material on a second surface region of the substrate via the print head of the three-dimensional printing device to form a second layer of the antioxidant material on the second surface region, wherein the antioxidant coating includes the first layer and the second layer.

12 . The system of claim 11 , wherein the controller is configured to control the print head to deposit the antioxidant material on the first surface region to form a penetrant type layer of antioxidant material on the first surface region of the substrate.

13 . The system of claim 11 , wherein the controller is configured to control the print head to deposit the antioxidant material on the first surface region to form a barrier type layer of antioxidant material on the first surface region of the substrate.

14 . The system of claim 11 , wherein the antioxidant material comprises at least one of a phosphorus based antioxidation compound or ceramic precursor compound.

15 . The system of claim 11 , wherein the processor is configured to control the print head such that at least a portion of the second layer overlaps a portion of the first layer.

16 . The system of claim 11 , wherein the antioxidant coating defines an overall thickness of approximately 2 microns to approximately 30 microns.

17 . The system of claim 11 , wherein the processor is configured to control the print head such that the first layer and the second layer each define a thickness between approximately one micron and approximately 10 microns.

18 . The system of claim 11 , wherein the processor configured to control the print head such that a third surface region of the substrate is not covered with antioxidant material, wherein the first surface region and the second surface regions of the substrate comprises non-friction surface regions of the substrate, and the third surface region of the substrate comprises a friction surface of the substrate.

19 . An article comprising:
a carbon-carbon composite substrate; and an antioxidant coating on a surface of the substrate, wherein the antioxidant coating includes a first layer of the antioxidant material on the first surface region of the substrate, and a second layer of the antioxidant material on the second surface region, wherein each of the first layer and second layer are formed by depositing the antioxidant material via a print head of a three-dimensional printing device.

20 . The article of claim 19 , wherein the first layer and the second layer each define a thickness between approximately one micron and approximately 10 microns
