The corrosion performance of steel coated with co-polyamide polymers and polyaniline in neutral salt spray (NSS) and accelerated corrosion testing is presented. A coating of the nylon polymer on steel is not sufficient to prevent corrosion in a chlor

The corrosion behavior of steel and polyaniline-coated steel in caustic media is presented. DC polarization curves show steel is protected from excessive corrosion forming a passive oxide layer in a caustic solution even in the presence of dilute chl

Cyclic voltammetric (CV) studies on steel were done to study the effects of oxalic acid on the polymerization of aniline. Steel is first passivated forming an iron(II)–iron(III) oxalate layer at potentials more negative than those used to polymeriz

Cyclic polarization measurements made on steel, iron oxalate-coated steel and polyaniline in a high pH solution and in the absence of chloride ions showed no tendency of the surface towards pitting corrosion. In all cases, the pitting potential was s
