Special Issue Information

Dear Colleagues,

Coatings and coating systems are frequently the first line of defense against corrosion for metals and alloys; this is especially the case in atmospheric corrosion scenarios because of the limited ability to provide for cathodic protection. However, exposure to the service environment causes ageing and degradation to the protective coatings themselves. The need to develop a new understanding of organic and inorganic coating degradation in various exposure environments so that predictions of coating protection can be made is driving new advances in experimental activities and modeling capabilities.

We hope that this Special Issue will serve as a forum for original research articles and reviews that are inclusive of—but not limited to—the following areas:

  • Theoretical and experimental research on changes in the mechanical and visual properties of coatings, especially under atmospheric exposure conditions.
  • Theoretical and experimental research on methods for evaluating the state of a coating.
  • Theoretical and experimental research on mechanisms of coating degradation through environmental exposure and loading conditions.
  • Computer modeling and simulations that can predict coating properties, performance, durability and reliability in service environments.
  • Experimental and theoretical research on accelerated test methods for predicting coating performance and reliability that incorporate physical, chemical, and electrochemical interactions, with an emphasis on relating test techniques with field performance data.

We look forward to receiving your contributions!

Electrochemical impedance spectroscopy (EIS) is a widely used method for monitoring coatings because it can be done in situ and causes little damage to the coating. However, interpreting the impedance data from coatings in order to determine the state of the coating and its protective abilities is challenging. A modified version of the rapid electrochemical assessment of paint (REAP) equivalent circuit is developed here, along with a method to calculate the impedance of a circuit using matrix algebra. This new equivalent circuit and the calculation method are used to analyze EIS data obtained from a two-layer commercial organic coating system immersed in NaCl solutions with different concentrations and at different temperatures. The matrix calculation method is validated by comparing results obtained from commercial analysis software to this method for two different equivalent circuits, and the parameter values are nearly equal. Physics-based models of the equivalent circuit elements are derived and used to obtain both initial estimates for the regressions and physics-based constraints on the model parameters. These models are integrated into the regression procedure, and the corrected Akaike information criterion (AICc) is used to compare fits between the new circuit and classic equivalent circuits. The AICc values indicate the new circuit results in better fits than classic equivalent circuits used for coatings analysis. Full article
