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 coatings. The FFC corroded area was shown to decrease at increased values of Cr(III) oxide coating weight. This was explained largely due to the insulating properties of Cr(III) oxide. Chloride entrapment within the tail caused filament tapering. FFC was shown not to initiate on traditional electro chromium coated steel (ECCS).
期刊介绍:
Electrochimica Acta is an international journal. It is intended for the publication of both original work and reviews in the field of electrochemistry. Electrochemistry should be interpreted to mean any of the research fields covered by the Divisions of the International Society of Electrochemistry listed below, as well as emerging scientific domains covered by ISE New Topics Committee.
