The scribed test sample on the left represents the traditional method of corrosion testing, in which researchers etch through both topcoat and primer layers to simulate damage and resulting corrosion. The new Accelerated Combined-Effects Simulation test chamber enables more realistic full-scale testing of specimens similar to the one on the right, by simultaneously subjecting samples to realistic fatigue testing and environmental conditions.
