In this work, we discuss the development of accelerated atmospheric corrosion test cycles designed to produce similar types of corrosion damage observed during field exposures while also highly accelerating the formation of that damage. These four cycles vary the times spent in three different ranges of RH (high, intermediate, and low) while maintaining a constant temperature. The ratios of testing time spent in each of these three RH ranges were inspired by the RH profiles obtained during field exposures in a variety of locations throughout the continental U.S. To ensure similar performance between the two testing labs involved in performing testing, extensive qualification of the test environment was performed prior to and during testing, including analysis
of the salt depositions as well as examination of the RH profile of the test chamber. After the test chambers were found to be performing similarly, lapped 7075 aluminum coupons with galvanic recessed fasteners were coated with a variety of military-grade coating systems, and subjected to 500 or 1000 hours in the test environment. Analysis of the resulting corrosion is presented and compared between the different cycles.
