文摘
- •
Marine atmospheric corrosion of Al-Mg FSBR joints was investigated.
- •
Severe corrosion on Mg (not in crevice region) was found due to general and galvanic corrosion.
- •
Al corroded in the coupled region near the rivet with the formation of gibbsite.
- •
Al corrosion was caused by the alkaline environment generated by cathodic reaction.
- •
The highly alkaline environment passivated Mg deep inside the crevice.
