Determination of the corrosion characteristics with conductivity measures and electrochemical polarization of steel coated with polypyrol which is conductive in various conditions

In this study, it has been made polypyrol covering with diffirent features on the surface of steel electrode. It have been compared results of test made by various electrochemical polarization techniques ( with or without damage) which show up in 0.2M NaCl medium of covering?s corrosion. As a result of these applications it has been determinated that pyrol?s concantration changed features of corrosion and quality of covering. Features of polypyrol?s corrosion which covers steel plates(surface :12cm2) have been determinated through following conductivities by Four Probe device and compared with non covered steel pattern. As a result of both of the measures it has been determinated that according to non covered patterns, polypyrol coating considerably increase corrosion resistance of steel.
