Organic coating systems with corrosion inhibitors are the primary means of protecting structures from atmospheric corrosion in harsh environments. Environmental compliance and a desire for increased performance continue to drive coating development and new product introductions. Current corrosion tests and measurement methods for selection of aerospace coatings often provide poor correlation to usage environments and do not assess the highest risk failure modes of localized corrosion galvanic attack and environment assisted cracking. Furthermore these tests do not quantify material interactions or corrosion rates needed to establish relative coating performance in accelerated tests outdoor exposures or service environments. New coating qualification typically includes accelerated corrosion tests outdoor exposures and aircraft trials; however these product introductions may take 10 – 15 years. There is an important need for improved measurement and monitoring techniques that can be used to accelerate new coating introductions and monitor coating performance in actual usage environments. A recently developed coating and corrosion monitoring system includes an extensible network of measurement systems each with multimodal sensors for comprehensive evaluation of the capacity of a corrosion protection system to control alloy free corrosion and galvanic corrosion maintain barrier properties and resist environment assisted cracking. The system is compatible with existing accelerated test chambers and suitable for use in outdoor service environments. An overview of the atmospheric corrosion and coating degradation sensors and measurement techniques to support comparative testing materials selection and site monitoring will be presented.
