Abstract:

The magnetic field (MF) affects the corrosion rate of N-80 carbon steel (which is frequently used in petroleum industry) in 3.8 Molar (or 12.5% weight percent). HCl was studied first at different conditions by implementing the potentiodynamic polarization (PDP) and gravimetric weight loss (WL) procedures. Response Surface Methodology (RSM) was next implemented to investigate and simulate the impacts of intensity of the magnetic field, time of magnetization, and elapsed time on the efficiency of corrosion inhibition (η). The test results revealed that acid magnetization considerebly decreases the rate of corrosion of N-80 carbon steel (CS) in the presence of HCl up to 93% so that it can be used as an eco-friendly and cost-effective substitute for the common corrosion inhibitors. The results also revealed that η enhances by enhancing the intensity of magnetic field. The morphology of the N-80 CS surface was also studied using SEM in the magnetized and normal HCl solutions.
