Evaluation of the effect of Tetramethylammonium hydroxide on the corrosion inhibition of A9M steel in industrial water an experimental, morphological and MD simulation insights.

Abstract : Corrosion inhibition performance of Tetramethylammonium hydroxide (TMAH), for A9M steel in industrial water (IW) was investigated using weight loss, potentiodynamic polarization and EIS measurement. The results showed that the inhibition efficiency of the TMAH increases with the increase of its concentration which acts as anodic inhibitor. The Characterizations that have been performed as the surface morphology by optical microscope, surface roughness and scanning electron microscopy (SEM) have proved that TMAH can exhibit good inhibition ability by forming a protective film on A9M steel surface. Molecular dynamics simulation were used to investigate the strength of the interactions between metal surface and the tested compound. The data obtained from theoretical and experimental studies were in reasonable agreement.
