Summary

3-D X-Ray imaging technology, when applied to advanced ceramics, is limited in some cases by detector sensitivity. This limitation can be overcome to some degree by the use of region-of-interest (ROI) reconstruction software. We have developed such software and applied it to 28 mm-diameter, injection-molded Si3N4 with known hole-type defects ranging in diameter from 25.4 m̈m to 508 m̈m. We have also applied the ROI concept to large (22 cm)-diameter Si3N4 turbocharger rotors, demonstrating the ability to resolve only the critical blade-hub region for each blade.
