Use of poly acryl amide Corrosion inhibitors for the C-Steel L80 in acid medium


This study included the use of poly acryl amide as corrosion inhibitor of the C-Steel in50ml of 15% HCl were used five different weights (0.5, 1, 1.5, 2, 2.5) gm of polymer toobtain different concentrations of the inhibitor and from weight lost in differenttemperature and times were obtained the inhibitor efficiency and covered surface area withpolymer and then calculated the thermodynamic constants. It was noted that in increase oftime and temperatures increases corrosion. The highest efficiency of the inhibitor has beenrecorded at the time of 3 hours and a temperature of 40 ℃.
