ABSTRACT:
In the present investigation 4-amino-3-phenyl-5-mercapto-1, 2, 4-triazole has been synthesized and studied as inhibitor for the corrosion of copper in 3.5 % NaCl solution. The inhibition efficiency of the compound have been evaluated by weight loss and electrochemical methods (Impedance spectroscopy and polarization curves). The surface study was done by using SEM techniques. The inhibitor appears to inhibit corrosion process through formation of protective film which was found to consist of Cu(I)-inhibitor complex, cuprous chloride, CuCl or CuCl2- complex ion or both on the surface.
