The effects of 4-NaTh-3-Thıosemicarbazide on the corrosion of Copper immersed in sea water has been evaluated. The inhibitor efficiency was determined by using three electrochemical techniques, Potential dynamic polarization (PDP), Impedance spectroscopy (EIS), and Open Circuite Potential (OCP) by using Potentiostat Instrument type compact stat (IVIUM) after immersion in sea water contain 3.5% Sodium chloride with presence and without corrosion inhibitor. A good inhibition efficiency is noticed which increases with an increase in corrosion inhibitor concentration. It was obtained that the inhibitor efficiency reached around 95% at 0,001 M from corrosion inhibitor. Both the cathodic and anodic curves are changed markedly in the presence of 4-NaTh-3-Thıosemıcarbazide. The mechanism of inhibition was proposed along the basis of the adsorption of the inhibitor molecules on the copper surface.
