The present disclosure provides a composite coating and a method for fabricating the composite coating. The composite coating comprises a polymer layer, a metal interlayer and an amorphous metal coating. The polymer layer is formed on a substrate and acts as a diffusion barrier layer, which is thick and dense enough to prevent the corrosive substances from penetrating into the substrate. The metal interlayer is formed between the polymer layer and the amorphous metal coating for improving the adhesion of the amorphous metal coating to the substrate.

The present invention provides a nickel-plated heat-treated steel sheet for a battery can (1), having a nickel layer with a nickel amount of 4.4 to 26.7 g/m.sup.2 on a steel sheet (11), wherein when the Fe intensity and the Ni intensity are continuously measured along the depth direction from the surface of the nickel-plated heat-treated steel sheet for a battery can, by using a high frequency glow discharge optical emission spectrometric analyzer, the difference (D2-D1) between the depth (D1) at which the Fe intensity exhibits a first predetermined value and the depth (D2) at which the Ni intensity exhibits a second predetermined value is less than 0.04 μm.

The invention relates to a multi-layer, preferably co-extruded, plastic film with improved modulus properties, which is suitable, in particular, for producing three-dimensionally shaped articles.

A glass laminate comprises an external glass sheet, an internal glass sheet, and a polymer interlayer formed between the external glass sheet and the internal glass sheet. The external glass sheet can be a thin chemically-strengthened glass sheet or can be a non-chemically strengthened glass sheet, the polymer interlayer can have a thickness of less than 1.6 mm, and the internal glass sheet can be a non-chemically-strengthened glass sheet or a thin chemically strengthened glass sheet.

A flat steel product for hot forming may be produced from a steel substrate that includes a steel comprising 0.1-3% by weight Mn and up to 0.01% by weight B, along with a protective coating that is applied to the steel substrate. The protective coating may be based on Al and may contain up to 20% by weight of other alloy elements. Also disclosed are methods for producing such flat steel products, steel components, and methods for producing steel components. Absorption of hydrogen is minimized during heating necessary for hot forming. This is achieved at least in part through an alloy constituent of 0.1-0.5% by weight of at least one alkaline earth or transition metal in the protective coating, wherein an oxide of the alkaline earth or transition metal is formed on an outer surface of the protective coating during hot forming of the flat steel product.

Provided is a plated steel sheet applicable for various purposes as in construction materials, household electric appliances, automobiles, etc. and, more particularly, to a hot dip plated steel sheet having excellent corrosion resistance and workability and a manufacturing method therefor.
