## Description

- description: 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.
