Metal-based coated stamped steel sheet and vacuum deposition manufacturing method thereof

The invention aims to solve the problems in the existing steel coating technology for stamping and forming, and aims to provide a metal-based coated stamping steel plate and a vacuum deposition manufacturing method of the metal-based coated stamping steel plate. Another object of the invention is to suppress the formation of brittle phases in the coating after hot forming and to reduce Kirkendall voids. The other purpose of the invention is to ensure the corrosion resistance of the hot stamping steel on the premise of improving the fracture toughness of the hot stamping steel. The invention relates to a metal-based coated stamping steel plate, which comprises a film-coated base material with a length, a width, a first surface and a second surface, the film-coated base material is a cold-rolled or hot-rolled steel plate or strip with any length, and at least one surface of the film-coated base material is provided with a metal-based coating coated by a vacuum physical vapor deposition method. And the thickness
