Study of the Structures of Thermally Formed Oxides on Amorphous SiAlCN Ceramics
EMSL Project ID
7193
Abstract
In this proposal, we propose to use NMR to study the coordination structural of Al in SiO2 (Al glass) thermally formed on the surface of amorphous SiAlCN ceramics. The SiAlCN are promising to be used as structural materials for next generation gas turbines and other high temperature applications due to their excellent oxidation and hot-corrosion resistance. Fundamental understanding the oxidation/hot-corrosion mechanism, which strongly depends on the understanding of network structures of the oxide layer, will lead to the design and synthesis of new materials, and form scientific basis for rational use of the materials.
