Abstract
A coating system is disclosed. The coating system includes a coating disposed on a substrate and a plurality of functionalized particles within the coating. The plurality of functionalized particles is configured to dissipate localized thermal flux from the substrate, where at least a portion of the plurality of functionalized particles are aligned.
Claims20
A coating system comprising:
- a coating disposed on a substrate;
- and
- a plurality of functionalized particles within the coating configured to dissipate localized thermal flux from the substrate, wherein at least a portion of the plurality of functionalized particles are aligned.
A vehicle propulsion system comprising:
- an engine having a manifold body;
- and
- a coating system coupled to the manifold body, the coating system including
- a coating disposed on the manifold body;
- and
- a plurality of functionalized particles within the coating configured to dissipate localized thermal flux from the manifold body, wherein at least a portion of the plurality of functionalized particles are aligned, at least a portion of the plurality of functionalized particles are sheets, and the plurality of functionalized particles have a thermal conductivity greater than 0.3 W/mK.
