摘要

Highlights?The steel substrate was treated by cerium-lanthanum based conversion coatings.?Post-treatment of cerium conversion coating by lanthanum gave rise to the superior corrosion resistance.?Post-treatment of cerium coating by lanthanum gave rise to the enhanced interfacial adhesion of epoxy coating.?Molecular dynamic (MD) simulations revealed the enhanced adhesion between the epoxy coating and steel surface.AbstractThe steel substrate was treated by cerium-lanthanum based conversion coatings. The effects of surface treatment of steel on the interfacial adhesion, cathodic delamination and corrosion resistance of the epoxy coating were studied through experimental and computational studies. Corrosion resistance of the epoxy coating applied on the untreated and surface treated samples was evaluated by electrochemical impedance spectroscopy and salt spray test. Results of experiments revealed that p
