“…The most widely used is conversion coating, which is based on chromate species. However, this approach is subject to increasingly stringent environmental regulations, which has spurred efforts to develop alternatives; these efforts have not had good results to date [ 5 , 6 ]. Coating adhesion is not only an issue with aluminum alloys; attempts have been made to improve the adhesion of coatings on other metal surfaces such as zinc.…”

An experimental protocol was studied to improve the adhesion of a polymeric poly(methyl methacrylate) coating that was modified with silver nanoparticles to an aluminum alloy, AA2024. The nanoparticles were incorporated into the polymeric matrix to add the property of inhibiting biofilm formation to the anticorrosive characteristics of the film, thus also making the coating antibiocorrosive. The protocol consists of functionalizing the surface through a pseudotransesterification treatment using a methyl methacrylate monomer that bonds covalently to the surface and leaves a terminal double bond that promotes and directs the polymerization reaction that takes place in the process that follows immediately after. This results in more compact and thicker poly(methyl methacrylate) (PMMA) coatings than those obtained without pseudotransesterification. The poly(methyl methacrylate) matrix modified with nanoparticles was obtained by incorporating both the nanoparticles and the methyl methacrylate in the reactor. The in situ polymerization involved combining the pretreated AA2024 specimens combined with the methyl methacrylate monomer and AgNps. The antibiofilm capacity of the coating was evaluated against P. aeruginosa, with an excellent response. Not only did the presence of bacteria decrease, but the formation of the exopolymer subunits was 99.99% lower than on the uncoated aluminum alloy or the alloy coated with unmodified poly(methyl methacrylate). As well and significantly, the potentiodynamic polarization measurements indicate that the PMMA-Ag coating has a good anticorrosive property in a 0.1-M NaCl medium.

“…However, the above-mentioned HDGS has certain drawbacks, such as relatively inadequate protection performance to cope with the increasingly harsh natural environment. As an alternative, a new strategy involving the combination of the pretreatment layer and organic coating, called duplex coatings, have been proposed (Dallin et al, 2018;Svoboda et al, 2018). Therefore, the exploration of novel duplex coatings has become a hot issue.…”
