摘要：

The inhibition action of (E)-7-chloro-3-(4-methoxystyryl)quinoxalin-2(1H)-one (Q1) and 7-chloro-2-(4-methoxyphenyl)thieno(3.2-b)quinoxaline (Q2) have been investigated for mild steel corrosion in 1 M HCl at different temperatures ranges (303-333 K) using potentiodynamic polarization curves. It was found that the studied compounds exhibit a very good performance as corrosion inhibitors for mild steel in 1 M HCl. Results show that the inhibition efficiency increases with decreasing temperature and increasing inhibitors concentration. Thermodynamic parameters such as adsorption heat (), adsorption entropy () and adsorption free energy () were obtained from experimental data at temperatures ranging from 303 to 333 K. Other thermodynamic parameters such as E (a), , and pre-exponential factor have been calculated and discussed. Adsorption follows the Langmuir isotherm with negative values of free enthalpy suggesting a spontaneous adsorption process.
