Full TextAbstract
The effect of magnetization of acid before usage (pre-magnetization technique) on the corrosion inhibition of carbon steel (CS) in 7.5, 10 and 12.5 wt.% (2.2, 3.0 and 3.8 M) HCl solutions were investigated by means of gravimetric weight loss method. Response Surface Methodology (Box-Behnken design) has been used to study and modelling the effects of magnetic field (MF) intensity, acid concentration, and elapsed time on inhibition efficiency. The experiments reveal that pre-magnetization is a suitable inhibitor in HCl solutions. The maximum percentage inhibition efficiency was found to be 93% for 12.5 wt.% HCl. The results showed that the inhibition efficiency rises with increasing MF intensity. The surface structure of the CS was examined by SEM (scanning electron microscopy) both in the normal and magnetized HCl solutions.
