Comparison of NDE techniques for sintered-SiC components
High frequency, bulk-wave ultrasonics detected defects in manufactured SiC components. In addition, gas-turbine blades and vanes were examined by scanning laser acoustic microscopy (SLAM). Comparative results obtained on simple shapes such as disks and bars by microfocus X-ray radiography, ultrasonics, scanning photoacoustic spectroscopy, and SLAM are discussed.
