dc.description.abstractPolyaniline (PANI) conducting polymer coatings have been obtained galvanostatically with various current densities (from 0.1 to 0.4 mA cm(-2)) and ZnNi alloy coatings have been obtained galvanostatically at 30 mA cm(-2) current density. Corrosion protection performances of monolayered PANI and ZnNi alloy coatings and multi-layered ZnNi/PANI and PANI/ZnNi coatings on st-37 low carbon mild steel (MS) have been investigated by an open circuit potential method, Tafel extrapolation method and electrochemical impedance method in 3.5 wt-% NaCl solution. In addition, the surface morphology of the coatings has been characterised by using scanning electron microscopy (SEM). Synthesising PANI films between two metal layers provided better corrosion protection to the steel. MS/PANI/ZnNi layer formation exhibited the biggest corrosion protection performance among all layer formations of the films and protected MS for up to 72 h.en_US
