- •
The PEO coatings are detached by an electrochemical method.
- •
A ~ 1 μm thick continuous thin layer is observed at the root of the coatings.
- •
The thin layer plays a main role in the anti-corrosion behavior of the coatings.
- •
Coating structure effects on the corrosion process change with immersion time.
