ABSTRACT:
Tafel curves and Nyquist plot measurements were performed on mild steel in potable water in the absence and presence of inhibitor formulations. The inhibitor namely: sodium gluconate and zinc ions. Results of potentiostatic polarization revealed that formulation function as mixed type inhibitor. Surface evaluation techniques like scanning electron microscope (SEM) and energy dispersive x-ray analysis (EDX) were used to determine the nature of the protective film formed onto mild steel surface.
