چکیده
|
Corrosion inhibition of mild steel by two new glassy materials correlated with the ternary system bi_2o_3-b_2o_3-p_2o_5 in hcl 1.0 m medium was evaluated using different technics: gravimetry and electrochemical methods (polarization and electrochemical impedance spectroscopy (eis)). the results show that the inhibition efficiency depends on the concentration of the two compounds studied (1bhp, 2bhp) and the temperature. the adsorption model obeys to langmuir isotherm. thermodynamic parameters were calculated and analysed. the morphology of the steel surface was characterized by scanning electron microscopy (sem) coupled with edx.
