    摘要: A multilayer metal-coated steel sheet comprising as a first layer a Zr coating layer formed on the surface of a steel sheet, and as a second layer an Al coating layer formed on said first layer. As another embodiment, also disclosed is a multilayer metal-coated steel sheet comprising as a first layer a Zr coating layer formed on the surface of a steel sheet, as a second layer an Al-Zr alloy coating layer containing Zr in an amount of 1% by weight to 50% by weight, formed on said first layer, and as a third layer an Al coating layer formed on said second layer.The multilayer metal-coated steel sheet of the present invention has an improved corrosion resistance, heat resistance and formability.

    摘要: The surface of a steel material is irradiated with ion beams, held at a temperature of 100.degree.-400.degree. C. and then subjected to vapor deposition plating in vacuo. The vapor deposition plating may be performed by successively or simultaneously depositing different plating metals. The temperature control may use the sensible heat of the steel material, wherein the vapor deposition plating is applied to the surface of the steel material, which is in the temperature range of 100.degree.-400.degree. C. during cooling after ion beam irradiation, in a vacuum atmosphere. Since the surface of the steel material is held at a temperature of 100.degree.-400.degree.C., a lot of active spots remain on the surface. The active spots serve as starting points for the vapor deposition of the plating metals. The obtained plating layer is excellent in adhesiveness, workability, corrosion resistance and conformability to paint.
