Degradation of Organic Coatings on Steel Investigated by Dynamic Electrochemical Impedance Spectroscopy [PDF]
ECS Transactions, 2006 Degradation of the organic coatings on steel has been investigated by the dynamic impedance measurements. The dynamic impedance was displayed on 3-dimension plots, whose axes were real and imaginary components and time. The time variation of the film resistance related to the permeation of water was monitored to discuss the corrosion mechanisms of
