Research Institution
The 5XXX-series aluminum alloys have high strength-to-weight ratios, good as-welded strength and excellent corrosion resistance. Changes in physical properties as a result of degradation processes of 5XXX-series (e.g., 5083, 5383, 5059) aluminum alloys are not completely understood. The susceptibility of 5XXX-series aluminum alloys to localized corrosion and stress corrosion cracking (SCC) can take place over time, and is accelerated under aggressive environmental, geometric, and structural conditions. In this proposal, Intelligent Automation, Inc. (IAI) along with Southwest Research Institute (SWRI) proposes to develop a self-powered multi-parameter wireless smart sensor network (Wi-Corr) for real-time monitoring of the corrosion in 5XXX-series aluminum alloys in combination with environmental conditions.
