摘要: Abstract Electrochemical impedance spectroscopy (EIS) and noise measurements (ENM) were used to evaluate protective properties of three different organic coating systems. The coatings under investigation two-component aerospace coatings, applied on aluminum substrate. They immersed in a 0.5 mol l−1 sodium chloride (NaCl) solution, within controlled flow cell tested for 1 year. modulus the low frequency domain resistance calculated compared. From EIS data, capacitances resistances performance estimated. electrochemical results are good agreement with final visual observations. this study yield ranking coatings.
