Notes According to the structure characteristics of grain, the ultrasonic impact-echo method of immersion was adopted to detect the cladding/propellant flaws accurately in this paper. By extracting various echo signals of defect characteristics, and then adopting the ultrasonic C-scan imaging technique, the flaw＇s image of specimen was obtained. Finally information on defect location and size is achieved by image denoising, binarization. Specimens of the known debonding are selectd for comparing with the results of this system, and the result shows that the method can detect the precise location of defects and have a good resolution.
