Abstract: A device for metal coating of fibers, for example ceramic fibers, by a liquid process, the device including a crucible containing a liquid metal bath through which a fiber is drawn to be coated with the metal, and a cooling system positioned downstream from the metal bath to solidify the metal sheath created around the fiber by capillarity. The cooling system includes at least one nozzle for ejecting a compressed gas towards the coated fiber, and the system is sized such as to solidify the metal on the periphery of the coated fiber over a length of no more than 200 mm.

Abstract: A method of coating ceramic material fibers in metal using a liquid technique and a device implementing the method. The method maintains a charge of molten metal in levitation in a substantially spherical shape inside a crucible and causes a tensioned ceramic material fiber to travel at a predetermined speed between a bottom pulley and a top pulley disposed on either side of the crucible such that a portion of fiber is immersed in the charge to be covered in a metal coating. During coating, the portion of fiber that is immersed in the charge is shifted as a function of the remaining volume of the charge such that the instantaneous height of fiber that is immersed in the charge remains substantially constant throughout the coating operation.

Abstract: The electrode wire according to the invention comprises a brass core (1) covered with a ? phase brass coating (2) having a structure fragmented into blocks (2a) between which the core (1) is exposed. The blocks (2a) have a thickness (E2) with a narrow distribution and produce a coverage of the core (1) according to a coverage rate greater than 50%. This produces a regular fragmentation of the coating, which improves the finish state of the machined parts.

Abstract: The invention relates to a wire (1) which comprises a copper or pinchbeck core (2) surrounded by a pinchbeck coating consisting of a continuous pinchbeck sub-layer (3) in phase ? and a superficial layer (4) with a fractured pinchbeck structure in phase ? enabling the appearance of pinchbeck in phase ? in the fractures (5a). In this way, the electrical discharge machining speed is essentially increased.

Abstract: A method of producing a metallic coating on an object emerging from a bath of molten metal. The object can for example be a wire or a plate. A magnetic field is created near the point of exit of the object. The object leaves the bath of molten metal via an exit channel containing a meniscus of the bath of molten metal. The thickness of the metallic coating is controlled as a function of the second derivative of the curve of the meniscus and of a capillary number Ca representing the ratio between the viscous forces of the molten metal and the forces of surface tension at the surface of the molten metal.

Abstract: The present invention relates to a method of producing a metallic coating on an object (4) emerging from a bath of molten metal (5). The object can for example be a wire or a plate. A magnetic field is created near the point of exit of the object. The object leaves the bath of molten metal via an exit channel (3) containing a meniscus of the said bath of molten metal. The thickness of the metallic coating is controlled as a function of the second derivative of the curve of the meniscus (6) and of a capillary number Ca representing the ratio between the viscous forces of the molten metal and the forces of surface tension at the surface of the molten metal.
