An automated disbond inspection system using an ultrasonic array for Metal Matrix Composite (MMC) tank track shoes has been developed. To ensure a reliable inspection, we investigated the test procedures and disbond identification criteria. A standard specimen was designed and fabricated for calibration of the transducer array. This specimen was also used to study the variables that affect the system performance, such as the repeatability and reproducibility with respect to acoustic coupling, and contact conditions, etc. Based on the statistic data analysis, an automated test procedure and criteria for detection and classification of MMC disbond have been established. By applying the inspection procedure to a set of track shoes, we have achieved more reproducible and reliable inspection results than previous tests. The inspection results were confirmed by ultrasonic C-scans.
