Definitions

  • the invention relates to a method and a. device for coating, continuously and at high speed, a large length of metal such as raw wire, round, bar, tube, flat, with a metal layer and which applies in particular to nickel plating of aluminum wires for electrical use.
  • each of these processes has both advantages and disadvantages, and it is therefore necessary to choose according to the desired goal, that which presents the optimum compromise.
  • the applicant has mainly aimed to resolve the problem of coating electrical conductors of aluminum or aluminum-based alloys. Indeed, if, for several years, it has been shown that aluminum and its alloys and, in particular, the alloy designated by the Aluminum Association under the name 6101, can replace copper, both from the point of view electrical resistivity and mechanical characteristics, it has also been found, however, that its use in the form of a wire is poorly connected to the connection systems currently used in electrical installations, in particular in high-stress applications or in aggressive atmospheres. In fact, under these application conditions, it is possible to observe a growth in the contact resistance, a possible source of harmful overheating. the good behavior of this type of driver and the safety of the installations. It was therefore necessary, to fully benefit from the indisputable advantages of aluminum and to impose it definitively in place of copper in the field of conductors, to find an economical process, which gives the wire a contact resistance stable over time and at least equivalent to that of copper.
  • the length of metal which may be a wire, a round, a bar, a tube, a flat made of aluminum, copper or other metal, is optionally initially subjected to a conventional degreasing or chemical pickling treatment to remove the surface stains, then it passes into a coating metal solution which is preferably nickel, but can be any other metal capable of being electrolytically deposited and chosen according to the problem to be solved.
  • a coating metal solution which is preferably nickel, but can be any other metal capable of being electrolytically deposited and chosen according to the problem to be solved.
  • an electrical voltage is then applied, which can be continuous or pulsed. If the positive pole of the current source is conventionally connected to an electrode immersed in said solution, on the other hand, to close the circuit, we no longer connect the negative pole directly over a part of the length of metal as in the prior art, but via an electrode which plunges into a conductive liquid through which passes said length, and which constitutes the liquid current outlet.
  • these temperatures are respectively around 35 and 50 ° C.
  • the plaintiff has already managed to realize nickel plating several ⁇ m thick with a running speed of the order of 30 m / minute and a residence time of less than 12 seconds, which constitutes a great improvement compared to the technique with mechanical contact, where, for an equivalent speed and residence time, the thickness was less than 0.5 ⁇ m.
  • a wire of aluminum alloy 6101 of diameter 1.78 mm, coated according to the invention, with a layer of nickel of 3 ⁇ m could be drawn to a diameter 0.78 mm, without any detachment or tearing of the nickel coating.
  • a 1350 aluminum wire, 5.67 mm in diameter could be drawn up to 0.78 mm in 16 passes with conservation of the adhesion of the nickel deposit while keeping, after each pass low contact resistance.
  • the applicant has designed an experimental device of great simplicity, of short length, comprising in the direction of travel of the length of metal successively at least one circular shaving die, a liquid current outlet constituted by a tank only 5 m long containing an electrolyte in which a negatively charged electrode is immersed, a coating tank of the same length containing the coating solution and in which a positively charged electrode is immersed, the two tanks possibly being separated by a system rinse.
  • This device is represented by the attached figure in which there is a coil (1) unwinding the length of metal (2), a shaving die (3), a tank (4) for taking a liquid current with an electrode. (5) connected to the negative pole of the current source (6) and immersed in the solution (7), a washing compartment (8), a tank (9) of coating containing the solution (10) in which is immersed l 'electrode (11) positively charged. At the exit from this tank, a rinsing (12) and drying (13) system is provided before winding the length of metal on the coil (14).
  • the treated wire is brought to 120 ° C. under the effect of the overcurrent which passes through it, then cooled to ambient temperature. It is considered that the resistance is good if the contact resistance R and the temperature of the connection do not change.
  • Table IV reproduces the tests in Table II, but using a coated wire at a running speed of 300 m / min. There are comparable results.
  • the present invention finds its application in all the problems of coating a long length of metal with an adherent metal layer and having both a ductility such that it easily lends itself to wire drawing operations, and a low contact resistance. and not scalable.
  • nickel-plating can be carried out on supply diameters, that is to say greater than the use diameter, believed to be reduced by the continuation, which makes it possible to extend the application of the method to other fields such as the fine wires of telephone wires, flexible cables and winding wires ...
