Summary

Continuous fiber-reinforced ceramic composite (CFCC) liners with environmental barrier coatings (EBCs) have been successfully field tested for nearly 14,000 hours in a Solar Turbines engine. The outer liner was chemical-vapor-infiltrated (CVI) SiC/SiC CFCC, and the inner liner was melt-infiltrated (MI) SiC/SiC CFCC. To determine their condition and assess operating damage, the liners were nondestructively evaluated (NDE) during various processing stages, as well as before and after the field test. The NDE techniques included pulsed infrared thermal imaging, air-coupled ultrasonic scanning, and X-ray computed tomography (CT). The NDE results and their correlations with destructive examination data are presented in this paper.
