A.] Keyword(s) steel rare earth filiform lanthanum cinnamate Summary The potential of lanthanum 4-hydroxy cinnamate to inhibit filiform corrosion on coated mild steel (AS1020) was investigated. The effectiveness and behaviour of this rare-earth inhibitor was examined with filiform corrosion scribe tests and Potentiodynamic Polarisation. The filiform scribe tests showed that lanthanum 4-hydroxy cinnamate, as a pigment in a coating, inhibited the initiation and propagation of both delamination and filiform corrosion on coated steel. The polarisation tests demonstrated that at pH 3, no significant inhibition was observed but a secondary passivation effect was present. At pH 9, inhibition on coated steel was found to be greater than that of the inhibition found at pH 6. The models of filament initiation and growth proposed by previous authors are also discussed.
