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
after forming the first layer, 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 material comprises at least one of a phosphorus based antioxidation compound or a ceramic precursor compound, and wherein the antioxidant coating comprises the first layer and the 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 at least a portion of the second layer overlaps a portion of the first layer.

5. 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.

6. 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.

7. 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 region 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.

8. 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.

9. 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.

10. The method of claim 1 , wherein the first layer is positioned between the second layer and the carbon-carbon composite substrate.

11. The method of claim 1 , wherein the first layer and the second layer are directly adjacent to each other.

12. The method of claim 1 , wherein the second layer is positioned directly on the first layer.

13. The method of claim 1 , wherein the first surface region and the second surface region of the substrate comprise non-friction surface regions of the substrate.
