Electrochemical Impedance Spectroscopy (EIS) Evaluation of Single Layer Coating Performance in Corrosive Environments

Talk Description:
Substrate preparation which includes the removal of contaminates along with abrading or etching to create a surface profile via mechanical or chemical methods have a major impact on the adhesion performance of applied coatings. For coatings, a primary performance characteristic is adhesion after exposure to corrosive environments. One of the consequences of corrosion forming under a coating is the loss of adhesion or delamination of the coating. We used electrochemical impedance spectroscopy (EIS) along with accelerated exposure testing (ultraviolet light cycling with condensation, salt-spray) to determine the influence of corrosion inhibitors on the adhesion of direct-to- topcoats.
