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.
  • WO2014/006229A1 discloses a silicon watch hairspring.
  • This hairspring has a multi-layer coating with a succession of alternating layers of TiO 2 and Al 2 O 3 , respectively.
  • 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. This material does, however, have a disadvantage: it has little or no plastic deformation domain, which makes it a relatively fragile material. Mechanical stress or shock can lead to breakage of the component. This fragility of silicon watch components is accentuated by their cutting in a silicon substrate, generally carried out using a deep etching technique, for example by deep reactive ion etching (DRIE). A specific feature of this type of etching is to form openings with slightly wrinkled sides which have surface flatness defects in the form of ripples (in English "scalloping").
  • DRIE deep reactive ion etching
  • An object of the present invention is to provide a watch component which does not include the drawbacks of the state of the art.
  • a first object of the invention is to propose 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 as defined by the claims.
  • 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.
  • FIG. 1 schematically illustrates a watch component 1 according to a first embodiment of the invention.
  • This watch component 1 comprises a main volume or core 2 made of silicon, originating for example from a step of cutting a silicon wafer. It further comprises a coating 10 which extends over its entire outer surface, over its entire periphery, more particularly over the periphery of its core 2.
  • this outer surface is formed by cutting a wafer, and mainly has three surfaces.
  • a first surface 3 is substantially planar and corresponds to the upper face of the cut wafer, a second opposite surface 4, substantially planar and parallel to the first surface 3, corresponds to the lower face of the cut wafer.
  • a third surface 5 forms a flank, which continuously connects the two aforementioned surfaces 3, 4.
  • the coating 10 is a multi-layer coating, which comprises a first layer C E , in contact with the silicon core 2 of the watch component 1, in an elastic material 11. It comprises a third outer layer C E in the same elastic material 11. These two layers are separated by a second layer CR in a more resistant material 12.
  • the layers C E are made of parylene and the layer CR 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 layers C E of elastic material 11 complete this intermediate layer to form a overall coating of constant thickness.
  • the C E layers are made of parylene and the CR layer is made of silicon oxide deposited by PVD.
  • the thickness of the coating 10 is not to scale, it is greatly increased in order to better visualize this coating, which is in reality very thin. Its thickness E is likely to vary within a certain range.
  • the coating 10 comprises at least one layer C E of elastic material 11 with a thickness greater than or equal to 0.05 ⁇ m, or even greater than or equal to 0.3 ⁇ m.
  • the coating 10 also advantageously comprises at least one layer C E of elastic material 11 with a thickness less than or equal to 5 ⁇ m, or even less than or equal to 3 ⁇ m.
  • the materials of the coating 10 may be different from those used in the embodiments described.
  • the elastic material 11 has a modulus of elasticity less than or equal to 10 GPa, or even less than or equal to 5 GPa, or even less than or equal to 3 GPa.
  • the elastic material 11 has an elongation at break greater than or equal to 10%, or even greater than or equal to 20%, or even greater than or equal to 30%.
  • This elastic material 11 can therefore be parylene, or alternatively a PTFE, an acrylic resin, silicone or a polymer from the urethane family.
  • Different layers of elastic material 11 of the same coating 10 can be in the same elastic material or in a different elastic material.
  • the more resistant material 12 is said to be “more resistant” in comparison with the resistance of the so-called “elastic” material. It has a modulus of elasticity greater than or equal to 30 GPa, or even greater than or equal to 45 GPa, or even greater than or equal to 60 GPa. Alternatively, it has a modulus of elasticity intermediate between that of the fragile material of the core of the watch component and that of the elastic material of the elastic layer. It advantageously has a modulus of elasticity greater than or equal to that of an adjacent layer of elastic material 11 increased by 50%.
  • This more resistant material 12 may be a metal or an alloy or graphite or an oxide, more particularly silicon oxide or silicon nitride. Different layers of more resistant material 12 of the same coating 10 may be in the same material or in a different material.
  • the coating 10 may comprise any other number of layers than the three layers shown. It may for example comprise at least two, or even at least three, or four, layers of elastic material 11 and at least one, or even at least two, or three, layers of more resistant material 12. In order to limit the influence thereof on the dimensions and behavior of the component, it advantageously comprises a maximum of four layers of elastic material 11 and a maximum of three layers of more resistant material 12, but could comprise more. It advantageously comprises an alternation of layers of elastic material 11 and layers of more resistant material 12. It further advantageously comprises a first inner layer of elastic material 11 and a last outer layer of elastic material 11.
  • the adjectives “inside” and “outside” are used in reference to any direction from the core 2 of the watch component 1 to the outside of the watch component 1.
  • Comparative bending tests were carried out on silicon specimens obtained by DRIE cutting from a silicon wafer, according to methods known to those skilled in the art.
  • the same treatments on the same specimen lead to different results from one watch component to another identical one a priori subjected to the same constraints. For this reason, it is necessary to carry out tests on batches of identical specimens, then to make a statistical analysis to determine whether or not an effect exists.
  • the following two batches correspond to specimens similar to batch OXY3 but covered with a pure, single-layer, uniform parylene coating, with respective thicknesses of 0.5 ⁇ m and 5 ⁇ m.
  • a pure, single-layer, uniform parylene coating with respective thicknesses of 0.5 ⁇ m and 5 ⁇ m.
  • the addition of such a coating made of elastic, low-strength material significantly increases the tensile strength of the specimens. Indeed, the average strength is around 5000 MPa.
  • the last batch corresponds to the second embodiment of the invention, comprising a coating consisting of alternating four layers of parylene of approximately 1 ⁇ m, and three intermediate layers of silicon oxide with a thickness of 0.01 ⁇ m, for a total coating thickness varying between 3.7 and 4.7 ⁇ m.
  • the average resistance of this batch exceeds 6000 MPa with minimum values above 4000 MPa: the invention therefore makes it possible to optimize the resistance of a watch component.
  • the invention therefore also relates to a watch component having an average resistance greater than or equal to 6000 MPa, and/or having a minimum resistance greater than or equal to 3000 MPa, or even greater than or equal to 4000 MPa.
  • the invention makes it possible to limit the scattering of debris.
  • a coating combining a flexible material (an elastic material as defined previously) with a more resistant material (also as defined previously) makes it possible to take advantage of the synergy between the two materials, not only to address the technical problem of non-dispersion of debris in the event of rupture, an effective protective effect thanks to the elastic material, but also at the same time makes it possible to optimize the resistance of the watch component, in particular thanks to the addition of a more resistant material to the elastic material in the thickness of the coating 10. This very advantageous behavior was unpredictable and therefore proves to be surprising.
  • the invention also relates to a watch movement and a timepiece as such, comprising one or more watch components as described previously.
  • the method for manufacturing a watch component according to the invention comprises a first phase of manufacturing a blank of a watch component, in a known manner.
  • this first phase may comprise an initial step consisting of providing a substrate made of fragile micro-machinable material.
  • This substrate is for example a silicon wafer.
  • the wafer is covered with a protective coating, in particular at least one of its two so-called upper and lower faces, for example with a photosensitive resin.
  • the method continues with a step of forming a pattern in the protective coating.
  • the pattern is produced by creating openings through the layer of photosensitive resin.
  • the protective coating providing openings constitutes a protective mask.
  • a step of etching the silicon wafer through the protective mask in particular by deep reactive ion etching (DRIE) then makes it possible to dig openings in the silicon at the level of the opening(s) of the mask, in order to obtain a blank of a silicon watch component.
  • DRIE deep reactive ion etching
  • Such a blank of a watch component can be formed by any other process than that mentioned above, for example by a laser cutting technique.
  • the blank obtained forms the core 2 of the watch component 1. It has a shape very close to the final watch component.
  • the invention relates to a second manufacturing phase, consisting of depositing a coating as described previously on all or part of the surface of said blank.
  • the coating deposition step is carried out by alternating the deposition of layers of elastic material and more resistant material respectively.
  • This deposition step can be done uniformly, by evaporation, CVD or ALD.
  • CVD chemical vapor deposition
  • PECVD plasma-enhanced chemical vapor deposition
  • the coating flow is oriented on the first surface 3, perpendicular to this surface.
  • the manufacturing method may comprise an intermediate step, before the step of depositing the coating, consisting of a step of smoothing and/or thermal oxidation of the surface of the blank of the watch component.
  • the core 2 of the watch component may be covered with an oxidation layer, for example a silicon oxide, before the deposition of the coating according to the invention.
