Ceramic and ceramic-coated components will be of increasing importance in the advanced engines now under development. Ceramics enable engines to run at much higher temperatures than the superalloys in more conventional engines can. The two options for noncontact high-temperature measurements of ceramic components are pyrometry and phosphor thermometry. This article describes how when properly applied as a thin coating, thermally sensitive phosphors can monitor the temperature of ceramic surfaces inside an engine.
