Corrosion Detection Under Coatings – Phase II

NCMS Project #: 141037

Problem: Coatings have productive lifespans and when a coating begins to deteriorate its effectiveness fades.  A key component to the maintenance and sustainment of coated surfaces is diagnosing when they are breaking down and when corrosion of the underlying surface has begun.

Benefit: Coatings have come a long way in retarding corrosion, but that lasts only as long as the coating’s integrity is maintained.  Having a method to detect potential coating failure mitigates the expense of corrosion and possible catastrophic failures.  It has significant benefit to the general public as the coating systems and NDE techniques are broadly applicable to systems employed in civilian infrastructure applications such as bridges, building architectures, pipelines, chemical processing plants and oil/gas exploration.  A fast, reliable and field deployable system would provide the warfighter with unprecedented levels of information regarding material state assessment and the ability to make informed decisions on asset maintenance.

Solution/Approach: In Phase II, the project will continue research on the more promising technologies downselected technologies from Phase I to solve and satisfy more specifically defined problems as well as develop them as either a lab tool or a field-deployable prototype to detect corrosion under coatings.
