Definitions

  • the invention relates to a method for manufacturing a composite part and more specifically to a metal-ceramic composite part, that is to say a part combining two distinct materials respectively based on metal and ceramic.
  • EP 2 380 864 describes the manufacture of a ceramic element inlaid by galvanic decors. This process brings many benefits but requires many implementation steps.
  • the object of the present invention is to overcome all or part of the disadvantages mentioned above by proposing a method of manufacturing a metal-ceramic composite part which has fewer steps to be implemented.
  • the invention relates to a method for manufacturing a composite part comprising the following steps:
  • the composite part formed of 316L steel and zirconia.
  • the composite part may be predominantly of metal or alternatively be predominantly ceramic.
  • the steps are simpler to implement and the blank formed of the two types of material is sintered in one step and not consecutively for each material which avoids the multiple manipulations of the intermediate parts as in the case of the background of the invention, more against all odds, and despite the significant difference in thermal expansion coefficient between 316L steel and zirconia could, via the bi-injection process described above obtain a complex 3D composite part bi-injected having a cohesion between the parts of steel and satisfactory zirconia.
  • said at least one first adjuvant comprises a binder and / or a surfactant and / or a plasticizer
  • said at least one first adjuvant comprises an organic compound and / or a polymer
  • said at least one second adjuvant comprises a binder and / or a surfactant and / or a plasticizer
  • said at least one second adjuvant comprises an organic compound and / or a polymer

  • the method comprises a final finishing step for improving the aesthetics of the composite part formed in step d).
  • the invention relates to a composite part obtained from the method according to one of the preceding claims, characterized in that the composite part combines, in a single piece, two separate materials respectively based on 316L steel and zirconia.
  • the composite part comprises two materials which are indissociable which may be predominantly of metal or alternatively be predominantly ceramic. Both materials being sintered at the same time, they form a single piece although being each of a different nature.
  • the composite part forms all or part of a case, a middle part, a horn, a dial, a flange, a telescope, a pusher, a crown, a a caseback, a needle, a bracelet, a link, a clasp, a decoration, a wall lamp or an ice cream
  • the invention relates to a metal-ceramic composite part.
  • This composite part has been devised for applications in the watchmaking field such as for example cladding elements of a timepiece.
  • the composite part according to the invention can not be limited to the cladding of a timepiece and more generally to watchmaking.
  • this composite part can be applied in the field of tableware, cutlery, jewelery or jewelery.
  • the composite part may form in particular all or part of a casing 1 such as the middle part 2 and the horns 3, a dial 4, a flange, a a bezel 5, a pusher 6, a crown 7, a bottom 8 of a housing, a needle 9, a bracelet 1 0 such as a link 1 1, a decoration 12, a wall 13, an ice 14 or a clasp.

  • the method comprises a first step a) for forming a first material comprising powder, for example, 316L steel and at least one first adjuvant and a second material comprising powder, for example, zirconia and at least one second adjuvant.
  • the first and second materials respectively formed by injection molding compositions, called "feedstock" in the field of injection each form powders whose grains allow shrinkage during substantially identical sintering.
  • said at least one first adjuvant and said at least one second adjuvant may comprise a binder and / or a surfactant and / or a plasticizer depending on the part to be manufactured and / or the sintering system used.
  • Said at least one first adjuvant and said at least one second adjuvant may thus comprise an organic compound and / or a polymer, optionally supplemented with an additive such as, for example, a gelling compound and / or a surfactant compound.
  • step b) for agglomerating one of the first and second materials in a mold to form at least a first portion of a blank.
  • the first material or the second material can be indifferently agglomerated.
  • the composite part may be "metal-based” or “ceramic-based”.
  • step b) can be carried out by injection, pressing, 3D printing or slip casting. However, preferably, the injection is used to allow obtaining more varied geometries.
  • step c) for agglomerating the other of the first and second materials against the first portion of the blank to form at least a second portion of the blank.
  • step c) can be carried out by injection, pressing, overmoulding, dip coating, 3D printing or slip casting.
  • the injection is used to allow obtaining more varied geometries.
  • steps b) and c) may consist of injection moldings of ceramic and metal also known as English abbreviations CIM ("Ceramic Injection Molding"), MIM ("Metal Injection Molding”) and PIM ("Powder Injection Molding”).

  • step d) intended to sinter the blank in order to obtain the composite part formed by 316L steel and zirconia.
  • step d) intended to sinter the blank in order to obtain the composite part formed by 316L steel and zirconia.
  • step b) it is thus possible to agglomerate, during step b), a zirconia forming a main body of the bezel with recesses and, in step c), 316L steel. agglomerating to fill said recesses and thus form one or more graduations.
  • a main composite piece of black color for example provided by the zirconia and having gray graduations for example made by the steel 31 6L.
  • the opposite is also possible.
  • the blank formed of the two types of material is sintered in a single step d) and not consecutively for each material which avoids the multiple manipulations of the intermediate parts as in the case of the background of the 'invention.
  • 316L steel is selectively chosen because it has good mechanical resistance to scratching and corrosion, is insensitive to magnetic fields and is non allergenic to wear. It is therefore understood that the 316L steel has similar qualities to those of zirconia and thus forms, in combination with it, a composite part perfectly suitable for particular parts of dressing a timepiece.
  • the composite part obtained according to the process can form a casing 1 whose middle part 2 is made of 316L steel and the horns 3 made of zirconia (or vice versa), a dial 4 made of zirconia whose index hours are steel 31 6L (or vice versa), a bezel 5 steel 316L with zirconia graduations, or links 1 1 bracelet 10 steel 31 6L with decors zirconia (or vice versa).
  • step d) may also comprise a debinding phase intended to remove said at least one first and at least one second adjuvant and, more generally, any additive used before the sintering phase intended to densify the blank.
  • a final finishing step to improve the aesthetics of the composite part formed in step d) is also possible.
  • Such a finishing step can typically include machining and / or brushing and / or polishing to make the composite part more aesthetically appealing.
