Electrochemical and conversion-electron Mössbauer spectroscopy(CEMS) methods have been employed to study the corrosion behavior of the electrodeposited Fe1-xZnx (x = 0.15–0.85) on a 1010 steel immersed in a 0.1 wt% NaCl solution at room temperature for two weeks. The corrosion rate measured by metal weight loss and electrochemical methods revealed that the Fe0.25Zn0.75 specimen was more corrosion resistant than the others. CEMS analysis showed that the corrosion product of the pure 1010 steel and the higher iron-containing FeZn alloys on steel in 0.10 wt% NaCl solution is β-FeOOH.
