Long-term corrosion behavior and mechanism of hot-dip Zn–Al–Mg coating in typical Chinese soil environments

Key Points

• Corrosion behavior is significantly affected by local soil environments, indicating the varied durability of coatings in different conditions.
• A key metric showed a remarkable increase in corrosion rate over the examination period conducted in typical Chinese soils.
• Observational analysis included assessing Zn–Al–Mg coating over multiple soil samples, focusing on long-term environmental exposure.
• This study highlights the need for tailored coating solutions to mitigate corrosion in diverse soil conditions.
