Investigational and Conceptual Study of HCl-H2CRO4 Acid Mixture towards Corrosion Behavior of Mild Steel Using Chemical and Polarization Methods

Mahima Srivastava

Abstract: The accomplishment of corrosion of mild steel in mixed acid solution was explored by using various criterions. The tests pointed out that due to adsorption of mixture of acids on the surface of mild steel, it served as a good medium for pickling as well as inhibition. The investigation of the surface morphology of the protective layer on the mild steel surface established that adsorption of molecules occurred via chemical adsorption following the model of Langmuir's isotherm. The effect of temperature and period of exposure on the corrosion performance in the presence of mixture of acids was studied in the range of 30?C-60?C and 10 minutes to 180 minutes, showing an increase in efficiency. The computed theoretical criterions presented remarkable support for cognizance of the mechanism revealed by the molecules of the acid mixture with mild steel surface and are in good accordance with the results.
