چکیده
|
Corrosion inhibition of mild steel in 0.5m h2so4 at 30°c with thiophene-2- ethylamine (tea) as inhibitor has been assess by quantitative structure activity relation (qsar) model and quantum chemical calculations. the results were evaluated using weight loss and electrochemical methods such as potentiodynamic polarization (pdp) and electrochemical impedance spectroscopy (eis). the results showed good performance of tea in corrosion protection which behaves as mixed inhibitor from pdp. the micrograph from fesem and edx dot mapping showed that the inhibitor adsorbed onto the metal surface with different distribution for s,c and n atoms which indicate less damage on the metal surface in the presence of tea. © 2015 penerbit utm press. all rights reserved.
