Study of corrosion and corrosion inhibition behavior of various metals/alloys in acidic/basic environment using inhibitors

News Article


Metals/alloys can undergo electrochemical oxidation in interaction with the various environment resulting in adverse effects on their properties. Hence, the protection of these metallic materials and thereby conservation of economic resources in technology has gained wide attention. In most chemical industries, the well-functioning of chemical plants very is essential. Different acid solutions are largely employed for the removal of unwanted scale and deposits from the metal surface, which causes metal dissolution. The destruction of metals in the acid environment needs to be addressed as a huge amount of material loss occurs due to acid wash every year worldwide. Hence, the addition of corrosion inhibitors to the corrosive medium is one of the most effective means to combat material corrosion. Among these organic compounds, plant extracts, biopolymers, ionic liquids, natural drugs, and nanocomposites are effectively used as corrosion inhibitors for many metals/alloys in various corrosive environments. The study includes the corrosion inhibition behavior of inhibitor compounds using electrochemical techniques, calculation and interpretation of kinetic and thermodynamic parameters, corrosion inhibition mechanism, and surface morphological behavior using various surface characterization techniques (SEM, AFM, EDAX, FTIR, XRD, BET etc.). Further experimental results can be correlated with theoretical study (DFT) and statistical analysis.
