Material degradation mechanisms such as galvanic, pitting and crevice corrosion limit the operational lifetime of structures and result in unsustainable long term maintenance costs. Recent studies of naval aircraft suggest that galvanic corrosion is the primary corrosion mechanism, in nearly 80% of the cases, when corrosion damage is observed on the aircraft. Corrosion maintenance is often very labour intensive so more effective scheduling can reduce costs. Therefore there is an economical need to move from a “Find and Fix” approach to a more efficient and cost-effective “Predict and Prevent/Manage” approach.
