Summary

Two high frequency ultrasonic techniques for bulk and surface flaw detection in ceramics are presented. Bulk defects of various types (WC, Si, SiC, Fe, C) are detected in the size range of 25 μm to 500 μm. Halfpenny shaped cracks as small as 60 μm in radius are also detected. The possibility of doing angular scattering and conversion to curved surface has been proven for both bulk and surface flaw detection.
