The corrosion behaviour of zinc has been investigated in chloride medium, in the absence and presence of acetate ions. The temperature effect has also been investigated by varying the temperature in a range between 298 and 328 K, while the pH was kept constant at 8.5. Polarization resistance (Rp) and activation energy (Ea) values were determined, by means of potentiodynamic and EIS measurements. Thermodynamical properties have been evaluated with help of current-potential measurement results. The role of temperature, ionic species and the formation of oxide film on anodic and cathodic processes are discussed. It was shown that zinc acetate [Zn(CH3COO)2] formation could provide important protection with other zinc corrosion products, against the attack of corrosive environment.
