تثبيط تآكل C-SteelL80 باستخدام البولي اكريل امايد مع الثايوفين-2-كاربوكسي الديهايد

الملخص EN

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.
