Corrosion Inhibition of Carbon Steel by Cerium Citrate Compound in NaCl Medium

More Information
  • Received Date: April 08, 2008
  • The efficiency of cerium chloride,cerium nitrate and cerium citrate was investigated for corrosion inhibition of carbon steel in 3.5% NaCl solution by potentiodynamic polarization,electrochemical impedance spectroscopy and surface analyses(XPS and SEM).The measurements demonstrated that these cerium salts all displayed strong cathodic behavioura for carbon steel in 3.5% NaCl solution,and the corrosion rate decreased with the addition of the cerium salts with a maximum decrease and critical value effect offered by cerium citrate.Scanning electron microscopy and X-ray photoelectron spectroscopy confirmed the formation of precipitates of cerium citrate on carbon steel,which contained cerium,iron,oxygen and carbon.
