| Outline of Annual Research Achievements |
Firstly, the main idea of the project was to link corrosion-induced hydrogen ingress into metals and real-time Acoustic Emission (AE) signals, but unfortunately proved to be "negative" according to the experimental data obtained so far. In the future, more investigation with improved framework will be conducted to further verify this original idea. On the other hand, thanks to this grant funding, one experimental framework, i.e., micro-electrochemical system equipped with in-situ high-speed microscopy and real-time AE monitoring, was successfully established; And one original electrochemical test approach, i.e., intermittent anodic polarization (IAP) test approach, was developed.
