Degradation of zinc-rich epoxy coating in 3.5% NaCl solution and evolution of its EIS parameters

The electrochemical characteristics in the degradation process of epoxy zinc-rich coating (80 wt% zinc particles) and epoxy varnish coating in 3.5% NaCl solution were studied comparatively by using open-circuit potential and electrochemical impedance spectroscopy tests. The coating morphology, the c...
