Abstract
This study included the use of poly acryl amide as corrosion inhibitor of the C-Steel in
50ml of 15% HCl were used five different weights (0.5, 1, 1.5, 2, 2.5) gm of polymer to
obtain different concentrations of the inhibitor and from weight lost in different
temperature and times were obtained the inhibitor efficiency and covered surface area with
polymer and then calculated the thermodynamic constants. It was noted that in increase of
time and temperatures increases corrosion. The highest efficiency of the inhibitor has been
recorded at the time of 3 hours and a temperature of 40 ℃.
