Effects of direct stray current on the performance of cathodic disbonding epoxy powder coatings

Abstract The influence of the direction and magnitude of direct (DC) stray current on the disbonding performance of epoxy powder coating was studied by using electrochemical impedance spectroscopy and scanning electron microscopy technology. The results show that the application of DC stray current...
