Description
Summary:•ZnFeCo alloy particles obtained on the carbon steel substrate by electrochemical deposition had more homogenous, smooth with pyrisma structure.•The ZnFeCo particles exhibited important barrier efficiency on carbon steel electrode.•Poly(aniline-co-o-anisidine), poly(aniline-co-pyrrole), poly(aniline-co-N-methylpyrrole) and poly(o-anisidine-co-pyrrole) copolymer films were synthesized on ZnFeCo particle plated carbon steel in sodium oxalate medium.•The corrosion resistances of copolymer film coated CS/ZnFeCo electrodes were fairly higher when compared with bare CS and CS/ZnFeCo electrodes.•Copolymer films synthesized on CS/ZnFeCo electrode provided the anodic protection to ternary alloy coating and carbon steel. Zinc–iron–cobalt (ZnFeCo) particles were electrochemically deposited on carbon steel (CS) electrode applying current of 3mA with chronopotentiometry technique. ZnFeCo particles had homogenous, smooth with prismatic structure. It was shown that the ZnFeCo particles exhibited important barrier effect on CS substrate. Poly(aniline-co-o-anisidine), poly(aniline-co-pyrrole), poly(aniline-co-N-methylpyrrole) and poly(o-anisidine-co-pyrrole) copolymer films were obtained on CS/ZnFeCo electrode. Evaluation of anticorrosion performance of copolymer coatings in 3.5% NaCl solution was investigated by using AC impedance spectroscopy (EIS) technique, anodic polarization and the Eocp–time curves. Copolymer films exhibited significant physical barrier behavior on ZnFeCo plated carbon steel, in longer exposure time.
