Therefore, in recent years, the demand of the automobile industry for ultra-high strength steel is increasing, but the use of ultra-high strength plates is affected by the problems of poor shape, high forming load, large rebound amount and the like of ultra-high strength plates during cold working. Therefore, a thermal forming technology (heating hot stamping steel to 850-950 degrees, preserving heat for 4-10 min to enable the steel to be uniformly austenitized, then rapidly transferring the steel into a die with a cooling system for stamping forming, rapidly cooling the steel in the die, converting austenite into martensite, thereby greatly improving the strength), and the tensile strength of parts manufactured by adopting the hot stamping steel can reach 1500MPa, so that the hot stamping steel is widely applied to the automobile industry at present, such as production of structural components such as B columns, door anti-collision beams, roof beams, bumpers and the like.

The hot stamping industry generally adopts bare board hot stamping, aluminum silicon coating hot stamping and galvanized sheet hot stamping, a large amount of oxide skin can be generated in the traditional bare board hot stamping process, and the stamped parts have no corrosion resistance; the aluminum silicon coating has good oxidation resistance when hot stamping parts, but has poor corrosion resistance; the galvanized sheet has the problem of LME (liquid metal brittleness) during hot stamping, has high cost and wide application range, and the preparation method and the device of the corrosion-resistant hot stamping part disclosed by the patent CN109821951A propose a method for electro-galvanizing after hot forming the part, and the method can effectively increase the corrosion resistance of the hot stamped part, but has the risk of hydrogen embrittlement during the electroplating process, and needs tempering treatment to remove hydrogen.
