The present invention relates to a cold-rolled steel sheet comprising: a base steel sheet; and a nickel or nickel alloy coating layer formed on the base steel sheet, wherein the adhesion amount of the nickel or nickel alloy is 50 mg/m.sup.2 or less.

According to the present invention, provided are a high-strength cold-rolled steel sheet and a manufacturing for manufacturing same. In the high-strength cold-rolled steel sheet, a metal layer is coated on a cold-rolled steel sheet to a thickness of nanometers, followed by annealing, thereby suppressing the formation of oxides of Si, Mn, and the like on the surface of the steel sheet to within a range in which the elution of Fe is not suppressed, and thus the high-strength cold-rolled steel sheet has improved phosphatability.

The invention relates to a method for coating a steel sheet or steel strip to which an aluminium-based coating is applied in a dip-coating process and the surface of the coating is freed of a naturally occurring aluminium oxide layer. In order to provide a low-cost method for coating steel sheets or steel strips that makes the steel sheets or steel strips outstandingly suitable for the production of components by means of press hardening and for the further processing thereof, it is proposed that transition metals or transition metal compounds are subsequently deposited on the freed surface of the coating to form a top layer. The invention also relates to a method for producing press-hardened components from the aforementioned steel sheets or steel strips with an aluminium-based coating.

The invention relates to a glass substrate including a stack of coating layers having control properties, in which stack comprises at least one niobium metal layer located between a layer of a dielectric material selected from Si.sub.3N.sub.4 or TiOx and a layer of a protective metal material selected from TIN or Ni—Cr, conferring solar control and heat resistance properties on the glass substrate.

A multi-layer PVD film stack contains high index of refraction base material(s), followed by a semi-transparent low index of refraction cap layer. The base layer(s) provide the color range of the film. The thickness of the cap layer dictates the degree to which the film retains the color properties of the base material and the reflectivity of the cap material. The cap layer not only increases the reflectivity of the base material, but it also decreases the reflectivity lost when the PVD film is topcoat lacquered. The lacquering is advantageous in protecting the PVD film but it decreases the reflectivity of the high index of refraction materials (generally n value>1.9 at 632 nm). These materials are desirable due to their color properties but are too dark after lacquering for many commercial applications. We address this problem by utilizing a high refractive index metal, or metals, as an opaque first layer followed by a thin semi-transparent second layer of a low refractive index metal. Upon topcoat lacquering, the resulting coating retains most of the aesthetically pleasing properties of the base metal(s) but minimizes the darkening of the metal(s) after topcoat due to the low refractive index of the second layer, which is in contact with the lacquer.
