A review of Corrosion Resistance Nanocomposite Coatings

“…EIS can be considered as a nondestructive technique [32,85,86]. The application of this technique in electrochemical systems considers the combination of physical and chemical interfacial processes with the components of an equivalent electrical circuit as an analogy of the electrochemical phenomena.…”

“…The application of this technique in electrochemical systems considers the combination of physical and chemical interfacial processes with the components of an equivalent electrical circuit as an analogy of the electrochemical phenomena. Therefore, it is possible to obtain the electrolyte resistance (R e ), the charge transfer resistance (R ct ), the polarization resistance (R p ), and the double layer capacitance (C dl ) as variables that allow the assessment of coating/substrate characteristics [32,86]. In addition, it is also possible to evaluate the corrosion rate and the porosity of the coating by comparing the R p values of the coating and of the substrate in the same electrolytic medium [32,82].…”
