The inhibition efficiency of Schiff base namely 2-[(2-Hydroxyphenyl)methylene] hydrazine carbothioamide, (ShB), on corrosion behavior of 304 stainless steel induced by sulfate reducing bacteria (SBR) in formation water was studied using weight loss measurements. The temperature effect on the corrosion behavior was studied at 30, 45, 65 ºC. Adsorption of ShB onto stainless steel surface was found to obey Langmuir adsorption isotherm. Schiff base- nano nickel nanocomposites were prepared with different weight ratio and used for coating the stainless steel surface. The electrochemical impedance measurements were used to identify the corrosion attitude of the coated stainless steel surfaces. The morphology of the coated stainless steel surfaces after immersion were investigated using scan electron microscope (SEM).
