One important factor affecting crevice corrosion of passive metals is the crevice geometry, e.g. the gap and shape of the crevice. Depending upon the materials properties, different crevice formers can affect the crevice geometry, e.g. a polymeric crevice former can conform to the surface roughness of a metal specimen. The objectives of this work are to investigate the crevice corrosion damage propagation of alloy 22 (N06022) with different crevice former materials and to address factors that may limit the initiation of localized corrosion and also factors that may slow or stop the continued propagation of corrosion.
