摘要：
Modified 9Cr-1Mo (mod.9Cr-1Mo) steel specimens were coated with polyvinylpyrrolidone based hybrid sol-gel coating doped with the corrosion inhibitor, 2-mercaptobenzothiazole. These coatings were characterized using atomic force microscopy and Raman spectroscopy. The corrosion resistance of surface mod.9Cr-1Mo steel in NaCl medium was evaluated using AC impedance studies. It was possible that the polymer based sol-gel coating prevented the aggressiveness of chloride attack by forming a complex with the inhibitor molecules and delayed the corrosion process on mod.9Cr-1Mo surfaces.
