Summary

As part of an effort to develop low-cost, nondestructive, non-contact methods to characterize large ceramic components, a 3-D X-ray tomographic imaging system was developed. An existing 320-kVp X-ray head was coupled to a large area, 40-cm by 40-cm, amorphous-silicon flat-panel detector as well as a precision motion control stage with new locally written software. The new flat-panel detector and software allow rapid data acquisition and high-resolution image reconstruction. Results to be presented include a discussion of the 3-D X-ray computed tomography system and detection capability for: a) internal cracking in large, >20 cm diameter gelcast Si3N4 turbine rotors, b) delaminations in 33 cm diameter SiC/SiC ceramic matrix composite gas turbine combustor liners, and c) special features inside EBC-coated and uncoated SiC/SiC composites.
