Corrosion Protection using Appliqu¿s with Embedded Corrosion Sensors

"The MDA must maintain high-value missile defense test and evaluation facilities in Hawaii and the Marshall Islands, among other remote locations, where the tropical marine environment is very aggressive. Corrosion protection is a critical issue forreliability and performance and maintenance of that protection is difficult given the remoteness and corrosiveness of the sites. DACCO SCI and Integument Technologies propose an innovative sensored appliqu¿ that not only will provide outstanding corrosionprotection, but will also allow health monitoring to de-tect degradation before it becomes serious. These appliqu¿s will incorporate in-situ corrosion sensors into the film structure so that appliqu¿ damage or deterioration and structure corrosion can bedetected before such degradation becomes serious and adversely affects the reliability of the structure/system. Consequently, the sensored appliqu¿ will enable condition based maintenance and predictive assessment. In addition to the MDA's test andevaluation facilities, both military and civilian aircraft are prime candidates for this technology. Potential markets include those that benefit from non-fouling, anti-corrosive, coatings that may require one or more of the following properties: 1) highthermal stability, 2) high resistance to chemicals, and 3) good insulative electrical properties. Films can be directly bonded or wrapped onto metals, plastics, glass and other composite surfa
