Oxidation Behavior of Non-Oxide Ceramics in a High-Pressure, High-Temperature Steam Environment
註釋This paper provides a review of two recent studies undertaken to examine the oxidation behavior of monolithic SiC and SiC-SiC composites in simulated and actual gas turbine environments. In the first study, a high-pressure and high-temperature test facility was used to expose a variety of structural ceramics and ceramic matrix composites to 15% water vapor carried in an air environment at 10 atm of total pressure and 1204°C. The second study involved the exposure of a SiC-SiC combustor liner in an industrial gas turbine for approximately 2300 h at a total pressure of 10 atm and peak liner temperature of 1150°C.
