Evaluating Material Loss of Steel Under Protective Coatings in Marine Environments

摘要

Over the past 20 years, the U.S. Navy has widely implemented the use of advanced ultra-high-solids UHS) coatings for the protection of ship tanks and voids to extend the life of tank coatings123. The Navy intends these coatings to provide 20 years of service. Experience to date has been largely positive concerning these coatings, although they are not immune to breakdown prior to the end of their intended service lives. In areas of breakdown, the maintenance community needs a suitable touch-up and repair coating and as part of this ongoing effort, the Navy sought methods to improve basic coating test methods to better assess repair coating performance. The program intended to conduct testing that would determine greater than 10 years of service life.
