Corrosion inhibition of carbon steel (K-55) in CO2-saturated 0.5 M KCl solution by polyacrylamide
Abstract
Polyacrylamide (PAM) was used to investigate the inhibition efficiency on corrosion of carbon steel (K-55) in 0.5 M KCl solution with CO2 through AC impedance, polarization curves, and SEM techniques under static and hydrodynamic conditions. The electrochemical experimental results indicated that carbon steel showed active dissolution behaviour in the absence and the presence of the inhibitor PAM. However, the Nyquist diagrams showed increase in RP values in the presence of inhibitor under static and hydrodynamic conditions, thus increasing inhibition efficiency. Potentiodynamic curves suggested that the inhibitor is mixed type in nature. SEM results showed that PAM was able to influence the flow dynamic properties of solution by decreasing the friction (wall shear-stresses) between the metal surface and flowing media, thus reducing the risk of flow induced localized corrosion
