Outline of Final Research Achievements |
Acoustic emission (AE) is a powerful tool to monitor the damage and impact in materials and structures. Process control is also one of the applications of AE measurement. However, it was very difficult to detect and analyze AE signals during material processing because of severe environment. Recently new technique to record AE signals such as laser AE and continuous waveform recording have been developed to apply to material processing. AE signals were successfully detected and analyzed in surface treatment such atmospheric plasma spraying, high velocity oxy-fuel coating process and shot peening. Condition monitoring of material processing using AE will be promising to improve the reliability of materials and structures.
