Structural Sensing of Corrosion in 5XXX-Series Aluminum Navy SBIR FY2010.3 Sol No.: Navy SBIR FY2010.3 Topic No.: N103-227 Topic Title: Structural Sensing of Corrosion in 5XXX-Series Aluminum Proposal No.: N103-227-0702 Firm: Intelligent Automation, Inc. 15400 Calhoun Drive Suite 400 Rockville, Maryland 20855-2737 Contact: Dan Xiang Phone: (301) 294-4160 Web Site: www.i-a-i.com Abstract: 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. Benefits: We anticipate the proposed multi-parameter wireless smart sensor network for corrosion monitoring in aluminum alloys has market in most industries such as aerospace and ship industry. The total market will increase in the future because high value structures, for technical and financial reasons are becoming more difficult to replace and hence they are left in service for longer becoming more prone to corrosion. IAI has very strong relationships with several large prime contractors with whom it has worked closely on major contracts over several years. We leverage our relationships and contacts with these partners to market our technologies and facilitate their insertion into relevant programs. Return
