It has been documented that the corrosion behavior of AZ91 (Mg–9Al–1Zn, wt.%) alloy is
strongly influenced by the morphology, distribution, and volume fraction of secondary
phases, however, the proposed corrosion mechanisms are questioned due to new
experimental findings. The present study focused on providing a more detailed
understanding of the corrosion mechanism of a peak-aged AZ91 alloy exposed to a chloride
environment by using scanning Kelvin probe force microscopy, immersion testing, optical …
