説明:

Hydrogen (H2)-bubble evolution has been proposed as an important source of acoustic emission (AE) during metal corrosion since 1976. However, direct evidence is still lacking. Here, we report a simple yet effective strategy to spatiotemporally isolate single H2-bubble events in sodium sulfate droplet corrosion of AZ31 alloy, which are synchronously captured by AE-driven high-speed observations. The individual AE waveform is directly related to the two-stage evolution of a single bubble, including detachment and bursting. Furthermore, by linking H2 evolution to the corrosion process, H2-bubble evolution-AE signals may provide a unique approach to evaluate the microstructure-dependent corrosion rate of Mg alloys.
