Hydrogen permeation potentiometry is a novel scientific approach for measuring oxygen reduction kinetics at buried organic coating/metal interfaces and correlated degradation. Scope of the technique is especially in those systems where the standard three electrode approach is not easy to apply. On the long term, the method will be of extreme importance for developing simulation tools for predicting coating performance.

Current efforts are in understanding how the tailored functional interface chemistry affects coating degradation kinetics
