摘要: Abstract Copolymer of poly(aniline-co-pyrrole) film was electrodeposited on low nickel stainless steel (LN SS) substrate from 0.1 M monomers (aniline and pyrrole) containing aqueous oxalic acid solution. The coatings were synthesized by means cyclic voltammetric technique. Then, the polymer modified depositing zinc particles over it potentiodynamic cathodic sweeps. corrosion performance investigated in 1 M HCl solution, using polarization electrochemical impedance spectroscopic techniques. It shown that exhibited a very permeability provided better protection to LN SS. This enhanced stability barrier properties may be due formation pore free adherent layer. Atomic force microscopy (AFM) energy-dispersive X-ray analysis (EDAX) used study morphology coating composition SS specimen.
