Thin-film Thermocouple for Measuring the Temperature of a Ceramic Matrix composite (CMC) Component

摘要

A thin-film thermocouple for measuring the temperature of a ceramic matrix composite (CMC) component comprises a first thermocouple leg and a second thermocouple leg deposited on a surface of a CMC component, where each of the first and second thermocouple legs has a length extending from a reference end to a working end thereof. The working ends of the first and second thermocouple legs are joined at a junction region on the surface. At least one of the first thermocouple leg and the second thermocouple leg comprises silicon carbide.
