Water uptake in commercially available epoxy coating on mild steel using impedance spectroscopy and gravimetrywas studied. The water content in the coating was determined using the Brasher-Kingsbury equation andvarious methods of coating capacitance calculation used in the literature. The obtained results were comparedwith reference gravimetric data. An overestimation of values obtained from impedance data in relation...

The use of the principal component analysis (PCA) permits the complex and quantitative analysis of the time dependence of electrical and electrochemical parameters of coated metal obtained by fitting impedance data. So far, changes in electrical and electrochemical parameters during exposure were analyzed independently. In this way, some of the information contained in the relationship between changes in parameters over time are...
