Characterizing the risk of corrosion due to environmental severity is critical for a variety of disciplines. However, a survey of the literature shows that there are multiple techniques and materials being used to assess environmental severity, making it difficult to compare results from different sources. To highlight this, groups from the Naval Research Lab and Naval Air Warfare Center – Aircraft Division co-deployed program-unique assessment techniques to address project-specific needs. During the post-exposure data analysis, the two teams combined the data sets in order to understand how different alloys perform in the same environments. This study will evaluate how alloy choices, along with techniques for characterizing atmospheric chemistry and real-time monitoring, can influence corrosion severity assessments. This work will also be used to aid in the development of the new standards in work through the AMPP SC-07 working committee.
