Abstract

This paper describes a systematic study into the initiation and propagation of filiform corrosion (FFC) on industrially important Cr(III) coatings applied to packaging steel. FFC was initiated by introducing an artificial scribe into a model PVB organic coating which had been applied to the metallic...
