Studies on the Corrosion Inhibition Property of Sr(ZnZr)xFe10O19-PANI Polymer Composite for mild steel in Strong Acidic Condition
Materials Today: Proceedings(2019)
摘要
Strontium Zinc Zirconium hexaferrite-polyaniline composite was synthesized by oxidative chemical polymerization of aniline using ammoniumperoxydisulphate as an oxidizing agent in an aqueous medium at 0°c ± 5°c. The synthesized composite were characterized by FTIR, XRD and SEM. The composite was evaluated as corrosion inhibitor for mild steel in 2M H2SO4solution using gravimetric method. Inhibition efficiency increases with increase in concentration of inhibitor ranging from 100 to 500ppm. Results revealed that the composite act as good inhibitor and could serve as an effective corrosion inhibitor for mild steel during industrial cleaning process. Potentiodynamic polarization, Electrochemical Impedance spectroscopy (EIS) and Open circuit potential (OCP) techniques were also carried out to prove corrosion efficiency of the composite at room temperature.
