ABSTRACT
Surface treatments of materials have attracted intensive studies in recent years, and considered as an important way for providing protection properties. In this paper, oxygen plasma treatment was used on API 5L X52 carbon steel. The produced deposit was characterized by different methods; optical and electronic microscopy, microhardness measurements and X rays diffraction. The resulting layer has been evaluated by electrochemical methods and pitting corrosion tests. The results showed that Fe2O3, which resulted from coating treatment by oxygen plasma, improved the superficial microhardness of steel. In chemical terms, pitting corrosion tests in corrosive solution showed a clear decrease of the weight loss and pitting percentage in coated coupons. Moreover, electrochemical corrosion tests (linear polarization and electrochemical impedance spectroscopy tests) showed that the produced deposit after coating gived a good protection against corrosion. This study demonstrates that oxygen implantation provides protective properties to API 5L X52 carbon steel.
