Document Language : Arabic 
Abstract : Coating by electro-active polymer, like polyaniline (PANI), is capable of well protecting and passivating the stainless steelٍ)SS(. But, porosity and anion exchange properties of CPs could be disadvantageous, particularly when it comes to pitting corrosion caused by small aggressive anions e.g. chlorides. Coating of SS by well adherent, non-porous and /or less anion exchange conductive polymer is important to form underlying stable passive film, the goal of this work. The project involves:  electrodeposition of poly(o-phenylenediamine) on stainless steel surface from aqueous solution containing o-phenylenediamine as monomer.  Investigation the deposited polymer layers by spectra and microscopic techniques.  Studying the effects of PoPD coating in the passivaing of stainless steel by immersion in aqueous solution for periods of time.  Investigation of the composition and characteristics of the formed passive film underneath the polymer layer by using surface analysis techniques.  Testing of the passive steel against pitting and crevice corrosion by electrochemical and corrosion measurements. Comparison between PoPD and PANI as coating layers of SS.
