Özet

Corrosion behavior of electrolytic coated carbon steel in 3% NaCl solution was investigated using potentiodynamic polarization, lineer polarization resistance, chronoamperometry, open circuit potential as a function of time and impedance (EIS) measurements. Zn and Ni coated carbon steel surfaces immersed into 3% NaCl solution during 1, 5 and 10 days were characterized using scanning electron microscope (SEM). According to the experimental results, nickel coated carbon steel corrosion resistance was higher than that of Zn coating. Accordingly, the corrosion rate of nickel coated carbon steel decreased by 89.6% compared to the zinc coating.
