    Corrosion Inhibition Of Carbon Steel Xc70 In H2so4 Solution By Ferrocenederivative3- (ferrocenylmethylamine) benzonitrile
    (University of Eloued جامعة الوادي, 2012-07-01) Zaiz, T.; Lanez, T.
    In this work, we studied the efficiency of corrosion inhibition of carbon steel XC70 in H2SO4 0.5 M aqueous solution using ferrocenyl derivativessynthesized in our laboratory, this compound is: 3-(ferrocenylmethylamine)benzonitrile. 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 inhibition of corrosion reached 84 % at a concentration of 50 ppm.

    Evaluation Of The Inhibitory Effectiveness Of Three Ferrocene Derivatives For Corrosion Of Steel Xc70 By Spectroscopy Of Electrochemical Impedance
    (University of Eloued جامعة الوادي, 2011-07-01) Rahim, O.; Ben Chenna, A.; Zaiz, T.; Chaouch, K.; Lanez, T.
    In this work, we studied the efficacy of corrosion inhibition of carbon steel X70 in HCl 1M solution using ferrocenyl compounds prepared in VPRS laboratory, these compounds are: N-(férrocenyl méthyl)-2-nitro aniline(Fc12), N-(férrocenyl méthyl)-3-nitro aniline(Fc13) and N-(férrocenyl méthyl)-4-nitro aniline(Fc14). The inhibitory potency of these compounds was determined by the electrochemical impedance spectroscopy (EIS). The overall results show that these compounds have varying percentages of inhibition. The adsorption of these compounds on the surface of the metal is a chemical adsorption. In HCl 1M, the compound Fc12 had the best ability of inhibition at a concentration of 70ppm (R = 91.24%).
