The overall objective of the ceramic nondestructive evaluation (NDE) program is to assess and develop NDE procedures for high-temperature ceramic components. Ceramic components are lighter than metallic components, can operate at high temperatures, and can be fabricated from inexpensive and abundant elements. Although previous work in this program has been on ceramic rotors, the current effort emphasizes ceramic heat-exchanger tubes. Ceramic heat exchangers would be useful in coal-fired Brayton conversion or waste heat-recovery systems. In the current NDE effort, several acoustic, optical, and radiographic techniques are under investigation for their effectiveness in testing ceramic heat-exchanger tubing. Progress on fracture mechanics analysis for ceramic tubing, as well as progress in the application of ultrasonic, acoustic-microscopy, dye-enhanced radiography, and infrared techniques to flaw detection in silicon carbide heat-exchanger tubing are reviewed.
