Title: A Novel Noninvasive Microwave Sensor for Quantitative Assessment of Degree of Sensitization in Marine Aluminum Alloys
Agency / Branch: DOD / NAVY
Contract: N00014-09-M-0346
Award Amount: $70,000.00


In this proposal, AlphaSense, Inc. (AI) and the Pennsylvania State University (PSU) detail the development of a novel noninvasive microwave sensor to quantify the DoS in marine aluminum alloys. The key innovations of this proposal include the following: a) DoS quantifications based on the correlation between the surface resistivity with the microstructures of the aluminum alloys, b) measurements of the surface resistivity with highly sensitive microwave cavity perturbation technique, and c) the implementation of a compact and portable sensor system. With such innovations, the merits of the proposed sensor and its advantages over other techniques include: a) Rugged, compact and low cost, b) Sensitive for DoS quantification, c) Noninvasive, d) Real- time analysis capability, and e) Easy and safe to the operators.
