Abstract
A preparation method of gradient high-silicon steel by molten salt electrolysis includes: weighing the inorganic fluoride salt and the inorganic silicon salt, mixing them uniformly and then drying; heating the electrolysis container over the melting point of the electrolyte, passing the inert gas through the electrolysis container, and connecting the electrode to the power supply to perform constant current electrolysis, after the electrolysis is finished, the cathode is taken out, washed and dried, placing the dried cathode in a constant temperature region of an annealing furnace; under a protective gas atmosphere, heating the cathode to the target temperature, and maintaining the temperature for a period of time; after the heat treatment, cooling the cathode to the room temperature, during which the cathode is always placed in the furnace.
