Corrosion Inhibition Of Carbon Steel Xc70 In H2so4 Solution By Ferrocene Derivative 4-(ferrocenylmethylamine) Benzonitrile



Authors : Zaiz T. . Lanez T. .

Abstract

In this work, we studied the efficiency of corrosion inhibition of carbon steel XC70 in H2SO4 0.5 M solution using ferrocenyl compound prepared in our laboratory, this compound is: 4- (ferrocenylmethylamine)benzonitrile (FC). The inhibitory potential of this compound was determined by electrochemical techniques based on Tafel segments. The results show that the studied compound has an efficiency of inhibition which depends on its concentration the adsorption of these compounds on the surface of the metal is a chemical adsorption. The compound FC had the best ability of inhibition at a concentration of 30 ppm (IE = 75.36%).
