In one aspect, a material system comprises a metal substrate and a first coating layer disposed on the metal substrate. A first electrode is directly disposed on the first coating layer, and a second electrode is disposed on the metal substrate. In one aspect, a method for determining material performance includes flexing a material system and detecting impedance of the material system with an electrochemical impedance spectrometer. The material system has a metal substrate, a first coating layer disposed on the metal substrate, a first electrode directly disposed on the first coating layer, and a second electrode disposed on the metal substrate.
