St udies of Elect rochemical Impedance Spect roscopy on Coated Steel wit h Artificial Defect

Elect rochemical Impedance Spect roscopy ( EIS) was applied to rapidly evaluate t he performance of organic coatings and t he characterization of t he protective properties of anticor2 rosive pigment s in t he presence of artificial defect in or ganic coatings. The result s showed t hat ar2 tificial defect met hod can rapidly evaluate t he performance of coatings and discriminate whet her t he pigment s in t he coatings have inhibitive.
