Monitoring the Electrochemical potential noise produced by coated metal electrodes

The protective properties of paints with polyvinyl phenol formaldehyde and cumar resin bases were tested on mild steel using electrochemical noise measurements. Amplitude spectra of low frequency electrochemical potential noise demonstrated a correlation between the rate and form of the corrosion potential. Such results suggest a practical nondestructive electrochemical corrosion monitoring technique for detecting general corrosion and pitting. The corrosion products were subjected to X-ray diffraction analysis and electron-probe microanalysis.
