| dc.description.abstract | Under the aggressive environment the metallic materials can be depredated as a corrosion process. One way to protect the metal surface against corrosion is applied the organic inhibitor material. The inhibitor is chemically adsorbed the surface of the metal forming a protective thin film. The current work is investigated the influences of tarmarix plant as an organic material source for inhibiting carbon steel in corrosion media. The obtained results show that the changes in weight loss in samples immersed in corrosion media contain 10% and 20% of Tarmaix material were less that without the inhibitor material. This may attributed to the Tarmaix material play a role in reducing the attaché of chlorine ions onto the substrate surface. Also, corrosion rate decreased with exposure time for all inhabitation specimens. One reason for this phenomenon may be attributed to the slower corrosion reactions emanating from test environment due to contamination by the corroding test metal in solution. In addition, the results revealed that after 5 hrs and 50 %, the inhibitor material showed a higher inhibition efficiency which was slightly above 90%. And, the plots of C\ɵ versus C gives straight lines with the linear correlation coefficient ( R2 ) values close to unity, which follow the Langmuir adsorption isotherm. The slope ranges of these line are 1.391- 1.623 within the used immersion times. Therefore, it can be suggested that the absorbed molecules form monolayer on mild steel surface. The strong appearing of functional groups such as C-OH (figure 4.6 b) inside the structure of polyphenolics in the plant leaf extract of tarmaix could be probably responsible for the reduction of metal ions and formation a protective layer improved the corrosion process within the inhabitation samples. | en_US |
