Recently, researchers succeeded in identifying defect levels in organic coatings with electrochemical noise (EN) measured in Single Cell (SC) mode.
A new work aims to develop field corrosion detection method for identifying the defect levels in organic coatings by using electrochemical noise (EN) measured at Singe Cell (SC) mode. An electrochemical sensor was used for defects identification, the results indicate that, as the defect levels rise, the amplitudes of the electrochemical current noise (ECN) increase.
Successful discrimination of protectivity levels
Further data analysis based on power spectral density (PSD), and discrete wavelet analysis confirmed that white noise level WL, and wavelet energy distribution can successfully discriminate the levels of protectivity of the organic coating.
