| 摘要： | Ship ballast tanks represent corrosion control nightmares. Ballast tanks are one of the most costly areas in which to apply coatings in both new ship construction and ship maintenance. Being subjected to intermittent wet and dry cycles of aerated sea water places extreme demand on corrosion control methods. Harsh service environments are coupled with necessarily complex tank geometries, especially in Navy combatants where weight and hull designs dictate small, irregular tanks with difficult accessibility. This research project was formulated to investigate alternative, environmentally acceptable, cost effective corrosion control solutions for ships ballast tanks. The first project began in 1980 and was entitled Cathodic Protection/Partial Coatings Versus Complete Coating in Tanks.' A series of steel ballast tank mock-ups were constructed which duplicate tank geometries. The tanks are large enough to allow access for surface preparation and installation of the various corrosion control methods. Previous testing results are documented in NSKP Reports 0158, 0205, 0280, and 0332. |
