The failure processes of a multi-layer coating system (zinc-rich epoxy primer, epoxy middle layer, and fluorocarbon topcoat) in four corrosion environments were studied with electrochemical impedance spectroscopy (EIS). The failure rate of the coating system in the four environments decreases in following order: immersion in a 3.5% NaCl solution under UV light, steam above a water surface at 45 ℃, salt spray at 35 ℃, and immersion in a 3.5% NaCl solution at room temperature. Although the failure rates of the coating system in the four environments are different, the variations of the phase angles at the middle frequency range, particularly 10 Hz, are very close to that of the coating impedance; hence they may be used as a qualitative evaluation parameter for coating inspection.
