Abstract of:

Corrosion inhibition of Sodium tungstate on carbon steel in 3.5 % NaCl

A. I. Ali      ,N. Mohamed and E.M. Mabrouk
Sodium tungstate was examined as corrosion inhibitors for carbon steel in 3.5 % NaCl solution using potentiodynamic polarization and electrochemical impedance spectroscopy methods. The inhibition efficiencies obtained from all methods employed are in good agreement with each other. The results obtained revealed that Sodium tungstate inhibits the corrosion of carbon steel in the investigated corrosive medium and the inhibition efficiency reached to81.9 %. Polarization curves reveal that Sodium tungstate can be classified as mixed inhibitor type.
