Corrosion Inhibition of Sodium Alginate on AZ31 Magnesium Alloy in Simulated Automotive Coolant

More Information
  • Received Date: February 14, 2011
  • The inhibition of sodium alginate on AZ31 magnesium alloy corrosion in simulated automotive coolant was investigated by electrochemical impedance spectroscopy (EIS) and polarization curves measurement. Results show that sodium alginate of 0.005 g/L had good inhibitive effect on the corrosion of AZ31 magnesium alloy. Sodium alginate is a cathodic type corrosion inhibitor and retards the hydrogen evolution of AZ31magnesium alloy.
