Surface assimilation and corrosion inhibition characteristic of water soluble Polyvinyl Alcohol on mild steel surface in 0.5M HCl solution

Abstract

Polymers lead to become emerging materials as corrosion inhibitors for mild steel in acidic media due to its larger surface area. This paper focuses on the characteristic of water solvent Polyvinyl Alcohol (PVA) at interface of Mild Steel under 0.5 M HCl, examined using electrochemical impedance spectroscopy, Tafel polarization and weight reduction techniques. These entire outcomes of the study of characteristic of inhibitor behaved as in well connection and the restraint proficiency, which shows up to 93.7% in 0.5 M hydrochloric acid for 3hrs term. An advanced form of high spatial resolution imaging of surface of mild steel at different stages was found by using scanning electron microscopy.
