The success of corrosion protective coating systems relies, to a great extent, on the coatings’ inherent barrier properties. This barrier property signifies the coating’s ability to withstand the permeation of sea water and oxygen, thus minimizing corrosion of the underlying metal. While various additives or pigments can promote the barrier property of coatings, one of the most common pigments is aluminum flakes [1-4].The idea behind their use is simple, and essentially relies on having the aluminum flakes in the coating oriented parallel to the underlying substrate. With them in place, the pathways for sea water and oxygen effectively increase, thus preventing the progression of corrosion. However, while having been employed in numerous coating formulations for many years, the evidence for the success of aluminum flakes as barrier pigments is still lacking.
