Electrochemical evaluation of corrosion inhibition of SAE 1010 carbon steel in 1M HCl by galactomannans
Keywords: Corrosion inhibition, EIS, Galactomannan, HCl, SAE 1010 c steel
AbstractThe 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.
