A ToF-SIMS investigation of the corrosion behavior of Mg alloy AM50 in atmospheric environments

- The usefulness of ToF-SIMS for studying the corrosion behavior of Mg alloys is evaluated.
- ToF-SIMS was used to analyze the conductivity of surface electrolytes.
- ToF-SIMS resulted in information on the composition of film formed on the Mg alloy surface.
- ToF-SIMS helps to learn more about the Mg corrosion mechanism at sub-zero temperatures.
