Abstract: A nanocellular single crystal nickel based material is provided having a thermal diffusivity in the range of 0.0002 cm{circumflex over ( )}2/s to 0.02 cm{circumflex over ( )}2/s and a thermal conductivity in the range of 0.024 W/mK to 9.4 W/mK. The nanocellular single crystal nickel based material may be used to form turbine engine components. The nanocellular single crystal nickel based material may be produced by providing a first solution containing a nickel precursor and deionized water, providing a second solution containing a structure controlling polymer/surfactant and an alcohol, mixing the first and second solutions into a solution containing a reducing agent to form a third solution, and processing the third solution to create the nanocellular single crystal based material.

Abstract: A process for coating a gas turbine engine component is disclosed herein. The process comprises applying a bond coat on a substrate of a gas turbine engine. A thermal barrier material is applied to the bond coat. A coating containing polynuclear aluminum oxide/hydroxide clusters is then applied to the thermal barrier material. The polynuclear aluminum oxide/hydroxide clusters are Al13 Keggin clusters having the formula [AlO4Al12(OH)24(H2O)12]7+, or are salts of the Al13 Keggin clusters called Al13 Keggin complexes. A gas turbine engine component comprising a superalloy substrate; a bond coat disposed on the substrate; a thermal barrier material on the bond coat; and a coating containing the polynuclear aluminum oxide/hydroxide clusters on the thermal barrier material is disclosed herein.
