摘要: Abstract The effects of steel surface treatment by a novel nanofilm based on praseodymium oxide the interfacial adhesion, corrosion protection properties and cathodic delamination rate polyester-melamine coating were studied combined experimental theoretical molecular dynamics (MD) quantum mechanics (QM) techniques. Field emission-scanning electron microscopy (FE-SEM), atomic force (AFM), X-ray photoelectron spectroscopy (XPS) employed to characterize morphology chemical composition nanofilm. results obtained from electrochemical impedance spectroscopy, pull-off tests demonstrated significant improvement steel/polymer decrease disbonding increase performance aid decoration Furthermore, outcomes derived atomistic MD simulations metal/polymer interface conducted in dry wet environments further evidenced strengthened adhesion onto surface-treated steel. It was also theoretically observed that electrostatic interactions major binding untreated/treated substrate.
