A. SAMIDE1,*
A Schiff base, namely N-(2-hydroxybenzilidene) thiosemicarbazide (HBTC) was investigated as an inhibitor for carbon steel in diluted acidic solutions (DAS) using electrochemical measurements.The morphology of the surfaces before and after corrosion was examined by scanning electron microscopy (SEM).The results showed that HBTC acts as an excellent corrosion inhibitor in DAS by suppressing simultaneously the cathodic and anodic processes via chemical adsorption on the surface, which followed the Langmuir adsorption isotherm. The inhibition efficiency increased with the increase HBTC concentration. The adsorption mechanism of the compound was discussed in terms of kinetic parameters deduced from the experimental data and UV-VIS spectrophotometry.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
