The performance of a surface-applied corrosion inhibitor for the carbon steel in saturated Ca(OH)2 solutions

In the present work, the performance of an amino alcohol based surface applied inhibitor was studied by the electrochemical techniques in saturated Ca(OH)2 solutions. The surface morphology of the carbon steel was observed by scanning electron microscope, and the energy diffraction spectrum was also tested. Results showed that the inhibitor used in this work demonstrated obvious inhibition efficiency on the carbon steel in saturated Ca(OH)2 solutions. The inhibition mechanism of the inhibitor lies in the quick adsorption of the active component on carbon steel surface.
