Experimental and MDS studies of corrosion inhibition of carbon steel by saccharinate sodium

Abstract

This work describes the successful performance of saccharinate molecule as an ecological corrosion inhibitor for carbon steel in 3% NaCl solution. A combination of experimental results such as (XPS, Raman, OCP, EIS, and potentiodynamic polarization) and other theoretical (DFT and molecular dynamic simulation) show that saccharinate ions provide very acceptable protection against corrosion of carbon steel. The behavior of carbon steel in the presence of different concentrations of saccharinate shows the high protective effect of this inhibitor against the corrosion of steel. These inhibitors act as mixed inhibitors with a stronger effect on the anodic side.
