Thin Protective Coatings on Metals Formed by Organic Corrosion Inhibitors in Neutral Media

“…Well-known methods of metal surface preparation include: immersion in a solution in which reactions of chemical deposition, e.g., of cerium oxide, or selective metal etching take place [8,[212][213][214][215][216][217][218][219][220][221][222], electrodeposition [8,223], sol-gel method [224], nanocomposite coatings [225] and templating method [8,226]. A special place is occupied by the creation of polymodal roughness using laser treatment, which in many cases is the most efficient method that positively affects the surface superhydrophobization upon HPA application [227][228][229][230][231][232]. Although it is beyond the scope of our review to consider the best SHP coating fabrication technologies, we note that optimizing the parameters of such technologies is undoubtedly very important.…”

“…According to [220], the surface energy of monolayer coatings decreases in the series: -CH 2 > -CH 3 > -CF 2 > -CF 2 H > -CF 3 . Not surprisingly, fluorinated organic acids (e.g., alkylcarboxylic and alkylphosphonic acids) or alkyltrialkoxysilanes are often successfully used to obtain stable SHP coatings [8,9,15,220,[227][228][229][230][231][232].…”
