N2 - Abstract: Extensive chemical data for the corrosion of zinc in hydrochloric acid, sulphuric acid, sodium hydroxide and sodium chloride are available in the respective literature. However, studies of the corrosion of zinc in sulfamic acid are minimal. The present paper highlights the work on the corrosion behavior of zinc in sulfamic acid, which can be used as a pickling agent. Studies were carried out with three different acid concentrations: 0.1, 0.25, and 0.5 M at a temperature range of 303–323 K. The measurements were done by potentiodynamic polarization and electrochemical impedance spectroscopy techniques. In addition, scanning electron microscopy, energy dispersive X-ray, and atomic force microscopy techniques were applied for the surface studies. Spectroscopic techniques like X-ray diffraction analysis and atomic absorption spectroscopy were used to substantiate the corrosion process. Studies showed that the corrosion rate increased with an increase in the acid concentration and temperature. Surface morphology studies and spectroscopic studies confirmed enhanced deterioration of zinc at higher acid concentrations.
