| Abstract | ||
| In this research Five steady weights (0.5) g. of polyacrylamide were mixed with five different volumes of thiophene-2-carboxildehyde (0.5, 1, 1.5, 2 and 2.5) ml to obtain five concentrations of inhibitor in (50)ml of 15% HCl. (C-Steel L80) bars were immersed in the prepared solution and the lost weights were calculated in different temperatures (40,60, 80 and 90) ℃ at different times (3, 4, 5 and 6)hrs. the covered surface area (θ)and the efficiency were calculated from the lose weights; then the thermodynamic constants were calculated. It was observed that the less corrosion was obtained by increasing the inhibitor concentration. | ||
