Abstract:
The subject of this invention is a textile product attenuating electromagnetic field and a device for manufacturing textile materials attenuating electromagnetic field by coating a textile material with coatings deposited by magnetron sputtering method, whereby the textile materials are intended for applications such as electromagnetic shields, used especially in hospitals, office blocks, dwelling houses and laboratories, and which may be used for manufacturing of wallpaper, curtains, blinds and roller blinds. The textile product has at least one layer (L1, L2, L3, L4) of metal and/or at least one layer (L1, L2, L3, L4) of metal oxide with the thickness below few micrometers, formula I, deposited on a substrate (S) alternately, where the number of the (L1, L2, L3, L4) layers depends on the coefficient of shielding efficiency of electromagnetic field by the textile product. Inside a vacuum chamber, above the conveying device fixed to the base (10) there is a three-layer anode in a shape of a part of cylindrical surface, mounted with insulators (6) on the base (10) fixed to the chamber housing. The anode, on the side of the target (1 1), has a sliding layer (5) and under this layer, a layer of supporting structure (4) while on the bottom, there is a temperature stabilizer (3) to which a cooling system made of a set of pipes (2) transporting the cooling medium is mounted. Above the three-layer anode there is a magnetron sputtering device (1) equipped with a rectangular target (11), connected to a supplier (27) which is coupled through a control system (26) with a computer unit (25). The control system (26) is connected through a valve controller (28) with a control valve (29), an instrument for measuring the length of a coated fabric (30), and simultaneously, through a engine velocity governor (31) with a motor (32) driving a two-way drive (9) of the conveying device.
Abstract:
The invention relates to a steel substrate provided at least at one side with a Zn-Mg coating layer and an intermediate layer between the substrate and the Zn-Mg coating layer, wherein the weight of the Mg in the coating layer is maximally 2.6 g/m 2 and wherein the intermediate layer has a maximum thickness of 5.0 μm. The Mg-content of the Zn-Mg coating layer is chosen in dependency of the thickness of the intermediate layer, resulting in good adhesion properties of the coating.
Abstract:
L'invention concerne une tôle d'acier munie d'un revêtement multicouche comprenant au moins une couche à base de zinc comprenant de 0,1 à 20% en poids de magnésium, surmontée d'une couche de protection temporaire de fine épaisseur comprise entre 5 et 100 nm et constituée de métal ou d'oxyde métallique choisi dans le groupe constitué de l'aluminium, du chrome, des oxydes d'aluminium AIOx, x étant strictement compris entre 0,01 et 1,5 et des oxydes de chrome CrOy, y étant strictement compris entre 0,01 et 1,5, ladite couche à base de zinc et comprenant 0,1 à 20% en poids de magnésium n'étant pas alliée avec ladite couche de protection temporaire, ainsi qu'un procédé de fabrication d'une telle tôle et d'une pièce.
Abstract:
A method for electroplating a substrate having an aluminum alloy surface comprises: applying a zinc layer onto the aluminum alloy surface; electroplating a first copper layer onto the zinc layer from an alkaline copper electroplating solution; electroplating a second copper layer onto the first copper layer from an acid copper electroplating solution; electroplating a Cu-Sn alloy layer onto the second copper layer from a Cu-Sn electroplating solution; and electroplating a chromium layer onto the Cu-Sn alloy layer from a trivalent chromium solution. The alkaline copper electroplating solution is substantially free of cyanide ion.
Abstract:
A security film (10) adapted to display a message indicative of tampering is disclosed. A light transmitting sheet (16) has a first layer on one surface (22), a release layer on a portion of the opposite surface (24), and a second layer covering the release layer and another portion of the opposite surface (26). The first layer is a metal and the second layer is a metal or a non-metal. An adhesive layer (14) on the second surface adheres the film to a substrate (12). Removal of the sheet from the substrate causes the sheet to separate from the second layer under the release layer making a release layer pattern visible on both the sheet and substrate as reverse images. A method disclosed includes metalizing a light transmitting sheet with a metal layer on one side and a release layer and a metal or a non-metal layer on the opposite side.
Abstract:
The invention relates to a method for a preliminary metallizing treatment of galvanized or zinc alloy-coated steel surfaces or joined metallic parts that at least partly have zinc surfaces, in a surface treatment encompassing several process steps. In the disclosed method, metallic coats of especially a maximum of 100 mg/m 2 of molybdenum, tungsten, cobalt, nickel, lead, tin, and/or preferably iron are produced on the treated zinc surfaces. Another embodiment of the invention relates to an uncoated or subsequently coated metallic part which has been subjected to the disclosed preliminary metallizing treatment as well as the use of such a part for making bodies during the production of automobiles, building ships, in the construction industry, and for manufacturing white products.
Abstract:
A wire (10) has a steel core (12), a nickel sub coating (14) and a zinc or zinc alloy top coating (16). The steel core (12) has a carbon content ranging from 0.15 per cent to 0.35 per cent. The nickel sub coating (14) and the zinc or zinc-alloy top coating (16) are preferably in a mechanically undeformed state. The use of the nickel sub coating allows to decrease the thickness of the top coating without decreasing the corrosion resistance. A possible application of the wire (10) is its use in mesh panels for fish farming.
