Paper Title:
Environmental Characterization of Monolithic Ceramics for Gas Turbine Applications
  Abstract

Over the last 30 years, a number of programs in Russia, Europe, Japan, and the United States have sought to introduce monolithic ceramic components into gas turbines with the goals of increasing efficiency and lowering emissions. High performance silicon nitride and silicon carbide ceramics typically have been leading candidates for use in these applications. Recent field tests involving silicon nitride vanes and blades have shown that these materials can experience significant recession due to the loss of the normally protective silica scale. This paper first summarizes key findings from these field tests and then describes a relatively simple method for evaluating environmental effects in a laboratory environment.
