An Auger and XPS survey of cerium active corrosion protection for AA2024-T3 aluminum alloy

Coupled SAM/SEM survey of cerium inhibitor migration towards corrosion pits in a conversion coating over AA2024-T3 substrate. [Display omitted] •XPS evidenced the proximity of the inhibitor with the surface AA2024 alloy.•Cerium conversion coatings with [Ce]=0.1M offer the best corrosion resistance.•...
