Corrosion Inhibition of Sodium Hexametaphosphate for Carbon Steel in KCl Solution

Article Preview

Abstract:

The influence of sodium hexametaPhosphate on the corrosion of carbon steel in 0.5 mol•L-1 KCl solution at 25 °C was investigated using weight loss measurements, potentiodynamic polarization curves and Scan electron microscope (SEM). The obtained results show that sodium hexametaPhosphate is an excellent inhibitor and the inhibition efficiencies exceed 87 %. The polarization measurements reveal that sodium hexametaPhosphate is an inhibitor mainly controlled by anodic process.
