Definitions

  • the present invention relates to a watch component made from a fragile material, in particular silicon. It also relates to a watch movement and a timepiece, in particular a wristwatch, comprising at least one such watch component.
  • the invention is based on a watch component based on a fragile material characterized in that it comprises at least one surface portion of fragile material covered by a coating comprising at least two layers of elastic material separated by a CR layer of material more resistant than the elastic material.
  • the invention is particularly concerned with watch components based on fragile materials, i.e. materials likely to break by generating several debris which dissociate from the watch component and scatter in a watch movement.
  • fragile material a non-ductile material which breaks without prior and residual plastic deformation.
  • These materials are preferably micro-machinable, i.e. 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 adapted 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 may be entirely or almost entirely formed from said fragile or brittle material, ignoring its thin coating which will be described later.
  • 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 may therefore be a hybrid material which has a fragile or brittle effect.
  • fragment material improperly to designate the entire heart of the watch component, including the parts of said heart which may not be directly in the fragile material at the base of the watch component.
  • the concept of the invention consists in covering at least a portion of the surface of the watch component, preferably the surface of the area of the watch component subjected to the greatest tensile stress, using a multi-layer coating comprising at least two layers of elastic material separated by a layer of material more resistant than the elastic material.
  • a coating forms a protective layer for the watch component to prevent the scattering of debris in the event of breakage of the component by holding the different pieces together.
  • the coating may be applied to the watch component. deformation, such a coating is considered to form an encapsulation of the watch component.
  • the coating 10 is a multi-layer coating, which comprises a first CE layer, in contact with the silicon core 2 of the watch component 1, in an elastic material 11. It comprises a third outer CE layer in the same elastic material 11. These two layers are separated by a second CR layer in a more resistant material 12.
  • the CE layers are made of parylene and the CR layer is made of aluminum oxide deposited by ALD.
  • FIG. 2 illustrates a second embodiment, which differs from the first in that the intermediate CR layer of the coating of more resistant material 12, made of silicon oxide, has a variable thickness at the sidewall 5.
  • This intermediate layer also has a constant thickness at the first and second surfaces 3, 4, this thickness being greater at the first surface 3 than at the second surface 4.
  • the two CE layers of elastic material 11 complete this intermediate layer to form a overall coating of constant thickness.
  • the CE layers are made of parylene and the CR layer is made of silicon oxide deposited by PVD.
