Oxidation of Rare-Earth Silicate Multilayer EBCs
Student: Benjamin Herren
Due to their high melting temperature, low density, and good thermomechanical stability silicon-based ceramics (SiC, Si
3N
4) are one of the most promising materials systems for high temperature structural applications in gas turbine engines. However, their passivating SiO
2 surface layer reacts with water vapor contained in combustion environments.
