X-RAY TOMOGRAPHY APPLIED TO NDE OF CERAMICS

Abstract

An x-ray radiographic NDE system specifically suited to three-dimensional tomographic reconstruction is described. The results of two applications of the system are discussed. The first is the reconstruction of a section of a ceramic gas turbine rotor blade. This demonstrates the system's ability to reconstruct parts with complex external shape. In the second, an assembly of ceramic components containing a 50 um gap is examined. The 50 um gap is detected.
