Abstract

The inhibition properties of galactomannans (GM) on low carbon steel samples immersed in 1M HCl were judged by advanced electrochemical assessments. The electrochemical results obtained by potentiodynamic polarization and electrochemical impedance spectroscopy of the inhibited electrodes were evaluated in contrast to the electrodes prone to corrosive solution and GM’s character in inhibition of corrosion was perceived. The results, qualitative and quantitative thus derived prove GM to be effective for corrosion protection of SAE 1010 carbonsteel in 1 M HCl.
