| Abstract: |
A new physics-based approach is proposed to predict galvanic corrosion in complex 3-D structures of multiple materials and finishes typical of Naval aircraft. This computational model will be modified as necessary and evaluated for its capability to predict galvanic "hot spots" that lead to corrosion of Naval air vehicles. The results will be compared to a test system known to experience galvanic corrosion in service. |
| Benefits: |
Successful physics-based galvanic prediction will make it possible to predict potential galvanic problems in the design phase, eliminating the problem from new weapons systems. It can also be used to predict the galvanic effect of changes in coatings and surface treatments, such as those required for environmental reasons, as well as to ensure that "fixes" applied to legacy systems to correct galvanic problems will work in the long term before they are put into production. The benefit of this software will be to reduce the very high costs of corrosion in Naval air vehicles, both new weapons platforms and legacy systems. |
