Tóm tắt

Extracts from Thai Nguyen Tobacco were prepared by extracting dried leave powder using distilled water. Corrosion inhibition efficiency of cn steel was tested in HCl 1M solution with and without Thai Nguyen tobacco extracts 2 g/l at different immersion time. The obtained results of electrochemical measurements showed that the corrosion rate of CT3 steel in studied solution decreased 74 pểcnt after 5 hours of immersion. EIS characterization and morphological characterization (SEM) of the surface of CT3 steel indicated the information of an inhibitor film on the sample surface. There is an excellent agreement between methods used for corrosion study in this research.
