For coatings that require long service lives, like those used in the automotive and aerospace industries, economic and environmental concerns necessitate a thorough understanding of expected coating failure modes. Such coatings are exposed to large temperature gradients, mechanical stresses, radiation, and aggressive species like salt and water, providing a host of variables to consider when testing and approving new coatings for widespread use. Little is understood about substantive complete links between microscopic degradation, mesoscopic ablation, and overall failure modes of coatings in service. Further, while test methods exist for general classes of automotive and aerospace coatings, such tests do not exist for specialty conductive coatings. We discuss first steps toward a test methodology for analyzing such coatings for suitability for field use and expected failure modes. In particular, we address characterization methods and design modeling for test coupons intended for environmental chamber inclusion.
