Definitions

  • the present invention relates to a watch component made from a fragile material, in particular silicon. It also relates to a horological movement and a timepiece, in particular a wristwatch, comprising at least one such horological component.
  • Silicon is a material with multiple advantages for the manufacture of watch components. On the one hand, it allows the simultaneous manufacture of a large number of small parts, with micrometric precision. On the other hand, it has a low density and a diamagnetic character. However, this material has a drawback: it has little or no plastic deformation range, which makes it a relatively fragile material. Mechanical stress or shock can lead to component breakage. This fragility of watch components made of silicon is accentuated by their cutting in a silicon substrate, generally carried out by a deep etching technique, for example by deep ionic reactive etching DRIE (standing for “Deep Reactive Ion Etching”).
  • DRIE deep ionic reactive etching
  • etching forms openings having slightly wrinkled sides which have flatness defects on the surface in the form of wavelets (in English “scalloping”). This results in a certain roughness of the etched sides which weakens the mechanical strength of the component.
  • flatness defects can generate crack initiation, in particular in the event of mechanical stress, and lead to component breakage. In the event of a breakage of a silicon watch component within a watch movement, the result is not only that the watch movement no longer works, but that there is also a large number of silicon debris scattered within the watch movement. watch movement, coming from the broken watch component.
  • An object of the present invention is to provide a timepiece component which does not understand the drawbacks of the state of the art.
  • a first object of the invention is to provide a watch component which does not produce a multitude of scattered debris in the event of breakage.
  • the invention is based on a watch component based on a fragile material characterized in that it comprises at least a surface portion of fragile material covered by a coating comprising at least two layers of elastic material separated by a CR layer in material more resistant than elastic material.
  • the invention is particularly interested in watch components based on fragile materials, that is to say capable of breaking by generating several debris which dissociate from the watch component and scatter in a movement. watchmaker.
  • brittle material we therefore mean a non-ductile material which breaks without prior and persistent plastic deformation.
  • These materials are preferably micro-machinable, that is to say obtained from micro-fabrication techniques involving photolithography.
  • the invention is particularly suitable for silicon, in any form, for example including doped or porous silicon, but could alternatively also be suitable for other materials such as for example diamond, quartz, glass, silicon carbide. , ceramic based on alumina or zirconia, fragile amorphous metals or sapphire.
  • Such a watch component can be fully or almost fully formed in said fragile or brittle material, disregarding its thin coating which will be described below.
  • a watch component could be based on such a material, that is to say comprise by weight at least 51% of such a material, or even at least 80% of such a material. It can therefore be a hybrid material which has a fragile or brittle effect.
  • fragment material improperly to designate the entire core of the watch component, including the parts of said core possibly not directly in the fragile material at the base of the watch component.
  • the concept of the invention consists in covering at least part of the surface of the watch component, preferably the surface of the area most stressed in traction of the watch component, with the aid of a multilayer coating comprising at least two layers. made of elastic material separated by a layer of material more resistant than the elastic material.
