Abstract
A substrate exposed to high temperatures, the substrate having a TBC layer that includes fibers of reinforcing material to add strength to the layer of TBC. The fibers are made from carbon nanotubes to withstand the high temperatures, and have a diameter of about 0.1 mm or less in order that a thin layer of TBC can completely cover and embed the fibers within the layer. A bond coat is applied to the substrate and the fibers are attached to the bond coat to limit the fibers from being pulled away from the substrate. The carbon nanotubes also provide for improved heat transfer through the TBC to improve the cooling capability of the TBC.
