Abstract: An assembly of an aluminum-based part and a press hardened steel part provided with an alloyed coating including in weight percent, 0.1 to 15.0% silicon, 15.0 to 70% of iron, 0.1 to 20.0% of zinc, 0.1 to 4.0% of magnesium, the balance being aluminum, on at least one of the surfaces thereof placed so as to be in contact with the aluminum-based part.

Abstract: An Al-steel assembly is provided. The assembly includes an aluminum-based element and a steel element on at least one surface of the aluminum-based element. The steel element has a metal coating made of a zinc-aluminum-magnesium alloy and includes from 2.3% to 3.3% by weight of magnesium and from 3.6% to 3.9% by weight of aluminum. A coated surface of the steel element is in contact with the aluminum-based element in an assembly zone and a protective coating coats the assembly around and adjacent the assembly zone. A body-in-white, further assembly and method are also provided.

Abstract: The invention concerns a method for marking a surface (S) by laser treatment, consisting of etching a plurality of patterns (M(0), M(1)) onto the surface by means of a laser source (2), said patterns being distributed across the surface according to a predefined tessellation of adjacent patterns, which involves: —etching each pattern from a corresponding virtual image generated in an image plane (20) of the laser source and physically reproduced by laser etching on the surface, in which each virtual image defines a frame physically reproduced on an area of the surface such that the corresponding etched pattern has an etched frame covering said area, the etched frames of adjacent patterns covering adjacent areas; and —the laser source is controlled in position between each etching of a pattern by means of a three-dimensional surface mapping system (3) coupled to the laser source; the method being remarkable in that it involves resetting the laser source, before etching each pattern, by matching up hook element

Abstract: The present invention provides an assembly of an aluminum-based element and an element made of steel provided on at least one of the surfaces thereof with a metal coating. The metal coating is made of a zinc-aluminum-magnesium alloy including from 2.3% to 3.3% by weight of magnesium and from 3.5% to 3.9% by weight of aluminum. The remainder of the metal coating is zinc, inevitable impurities and possibly one or more additional elements selected from among Si, Sb, Pb, Ti, Ca, Mn, Sn, La, Ce, Cr, Ni or Bi. The coated surface of the steel element is in at least partial contact with the the aluminum-based element. The contact is brought about by a layer of adhesive or sealant having a thickness of less than 5 mm. The present invention also provides a part for a vehicle including at least one assembly and a vehicle.

Abstract: A protective device for a male end of a component of a threaded tubular connection for drilling and working hydrocarbon wells is externally provided with at least one threading and includes a free terminal portion. The device includes i) a protector body produced in the form of a first sleeve and arranged to protect at least a portion of the external threading and the free terminal portion, ii) a sealing element for positioning in contact firstly with the component, at least at a portion located downstream of the external threading of the male end, and secondly with the protector body to provide a first seal downstream of the external threading, and iii) a fixing mechanism displacing the sealing element and/or protector body radially towards the component, defining open and closed positions of the device in which the sealing element and/or the protector body are respectively not in contact and in tight contact with the component. Further, the first seal is obtained in the closed position of the device.

Abstract: An integrated circuit is provided that comprises a substrate of silicon and an interconnect in a through-hole extending from the first to the second side of the substrate. The interconnect is coupled to a metallization layer on the first side of the substrate and is provided on an amorphous silicon layer that is present at a side wall of the through-hole, and particularly at an edge thereof adjacent to the first side of the substrate. The interconnect comprises a metal stack of nickel and silver. A preferred way of forming the amorphous silicon layer is a sputter etching technique.
