GDOES semiquantitative composition profile of AA2024 coated with a multilayer sol–gel film containing cerium nitrate. The sol–gel film consists of two layers produced with a 0.4 M inorganic precursor solution. The insert in the figure evidences the trend of Ce signal in the sol–gel coating (Reprinted from Prog Org Coatings, 69, Andreatta F, Paussa L, Aldighieri P, Lanzutti A, Raps D, Fedrizzi L, Corrosion behaviour of sol-gel treated and painted AA2024 aluminium alloy, 133–142, Copyright (2010a), with permission from Elsevier)
