Abstract
In this research, the magnetoelectropolishing method was used to prepare the surface of 304SS steel. The electropolishing process has been carried out in different modes including without magnetic field, Lorentzian force perpendicular to the surface outward, Lorentzian force parallel to the surface and Lorentzian force perpendicular to the surface inward. The methods of scanning electron microscopy, atomic force microscopy, potentiodynamic polarization test and electrochemical impedance were used to check the surface morphology, elemental composition, surface roughness and corrosion resistance of the samples in each state. According to the results, the direction of the magnetic field and in fact the direction of the hydrodynamic flow resulting from the Lorentzian force has a decisive contribution to the surface properties of the sample such as morphology, roughness and corrosion resistance. The best results occurred when the Lorentzian force was parallel to the surface. In this case, the amount of iron on the surface reaches 69.94%, which is the lowest amount compared to other cases of magnetic field placement, and the amount of iron in the case where the magnetic field does not enter the system is 73.52%, which indicates an improvement in corrosion resistance, as well as the results Potentiodynamic polarization also confirms that the maximum harvesting rate is when the Lorentzian force is parallel to the surface. Based on the results, the magnetoelectropolishing method is suggested as an efficient method to improve the surface properties and corrosion resistance of stainless steel.
