The direct losses to the U.S. economy attributed to corrosion each year exceed $300 billion. The methodologies and materials arising out of the Phase II effort can be applied to protect not only steel, but aluminum and magnesium. For, example, the U.S. Navy, the U.S. Air Force and commercial airlines need low-toxicity, high-performance corrosion inhibiting additives for corrodible aerospace aluminum alloys. New and effective corrosion inhibitors could replace the toxic chromates that are still being used in aerospace applications. Protective coatings employing our corrosion inhibitors could be used for low-toxicity corrosion protection for metals employed in a wide range of applications, including, automotive, aerospace, bridges and buildings. Additionally, the corrosion inhibitors could be used in related products such as adhesives and sealants where low toxicity corrosion protection is desired.
The proposed technology will have primary application to the ground support equipment and facilities at KSC, but the proposed technology could be used at any location where NASA maintains either equipment or facilities exposed to corrosive environments. The compositions of TDA's corrosion inhibitors and the nanostructured carriers arising from the Phase II efforts can be used as a low-toxicity, high performance corrosion inhibiting additive for protective coatings on the structural steel that makes up most of the ground facilities at KSC. Furthermore the methodology can be used to identify corrosion inhibiting packages for other metals and alloys that NASA needs to protect from the environment.
