Immersion tests and electrochemical tests results showed that Zn2+ had a significant inhibition effect on corrosion of SM490Y. The results of EDS and XPS showed that Zn2+ was incorporated in the oxide films by making a strong bond and formed zinc hydroxide or zinc oxide which can cover the surface of carbon steel. It is suggested that Zn2+ forms a protective film which can efficiently prevent break down of surface film by Cl- and inhibit the corrosion.一般社団法人 日本鉄鋼協会 (The Iron and Steel Institute of Japan)2021-12jpnjournal articleNAhttp://hdl.handle.net/2115/84055https://doi.org/10.2355/tetsutohagane.TETSU-2021-0370021-1575鉄と鋼 : Journal of the iron and steel institute of Japan1071210661073
