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

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 ℃.
