Abstract |
The study of the inhibitory efficacy of prop-2-yn-1-ol, methyloxirane for corrosion control of mild steel in concentrated hydrochloric acid (18.5%) at temperature 80 °C (chemical pickling conditions of steel) was investigated using electrochemical and gravimetric methods for different concentrations. Using weight loss, and potentiodynamic polarization techniques and the morphological structure, the results shows that inhibitor had an excellent protection. The substance has demonstrated remarkable inhibition efficiency, and its inhibitory characteristics are stronger as concentrations increase (Inhibitory efficacy of up to 91 % for 1.2g/L). Based on the polarisation curves, the addition of the inhibitor in the HCl solution induces the decrease of the anodic current corresponding to the attack of the metal. The morphological structure was examined by scanning electron microscopy, which clearly shows this inhibitor's good protection, which delays the acid attack of bare steel with a uniform and bright pickling appearance. |
