This reduction translates to an increase of approximately 1.5 percent in combined cycle efficiency. DOE Funding: $494,394; Non-DOE Funding: $123,599; Total Value: $617,993 ...
Oxide-Oxide Ceramic Matrix Composites
WebJul 1, 2024 · Several commercial metallic alloys, including silver and zirconium-based brazing materials, exhibit good wetting and joining behavior with ox/ox CMC. However, they have a lower mechanical strength and poor oxidation resistance at 550 °C in air [25], which is much lower than the expected working temperatures of ox/ox CMCs (800 °C–1000°C). WebA zirconia based coating is preferably applied on the surface of the CMC substrate, especially with a ceramic bond layer, which is preferably alumina in the case of Ox-Ox … how to change mac keyboard to windows
