a Corrosion weight loss. The error bar is the standard deviation of three measurement results; b corrosion rate derived from corrosion weight loss; c cross-sectional morphology after 72 and 576 h of corrosion. The area marked by the yellow dashed line represents the relatively dense inner rust layer, while the area marked by the pink dashed line indicates the loosely structured outer rust layer.
