Abstract
Provided are discs and bores of a gas turbine engine having one or more graphene layers and methods of preparing the same. The one or more graphene layers are disposed adjacent to the disc rim and/or bore to improve heat transfer and reduce oxidation of the discs. Methods of preparing the graphene layers and systems for using the same are provided.
Claims16
A disc comprising:
- a disc defining an outer surface, wherein the disc comprises a base material, and
- one or more graphene layers embedded in the base material such that the one or more graphene layers is not exposed from an outer surface of the base material,
- wherein one or more of the graphene layers is doped.
A disc comprising:
- a disc defining an outer surface, wherein the disc comprises a base material, and
- one or more graphene layers embedded in the base material,
- wherein the outer surface comprises a front surface, a back surface, and a disc rim, wherein the disc rim is perpendicular to the front and back surfaces and is defined by the circumference of the disc, and
- wherein the one or more graphene layers are uniformly embedded in the base material along an entire length of the disc rim.

A method of preparing a disc, the method comprising:
- applying graphene to a base material of a disc,
- forming the disc such that one or more layers of graphene are embedded in the base material such that the one or more graphene layers is not exposed from an outer surface of the base material, and
- doping the one or more layers of graphene.
A method of preparing a disc, the method comprising:
- applying graphene to a base material of a disc, and
- forming the disc such that one or more layers of graphene are embedded in the base material such that the one or more graphene layers is not exposed from an outer surface of the base material,
- wherein the one or more layers of graphene are adjacent to a bore of the disc.
A gas turbine engine comprising:
- a disc defining a disc rim and a bore, the disc comprising a base material;
- one or more blades disposed along the disc rim of the disc;
- and
- a shaft disposed through the bore of the disc,
- wherein the disc comprises one or more graphene layers embedded in the base material such that the one or more graphene layers is not exposed from an outer surface of the base material.
