    Field of the invention
    The invention relates to an article decorated for a timepiece or jewelery and more specifically, such an article comprising high-end decor decorations.
    Background of the invention
    It is known to produce items decorated as dials of timepieces using the so-called "cloisonné" technique. This technique consists of fixing on a substrate folded metal son able to form boxes which are then filled with enamel paste. In a final step, the whole is baked in order to turn the enamel paste into enamel.
    However, this technique is crude and does not allow the realization of fine and complex decorations but is rather reserved for the coverage of large flat surface homogeneously and upscale. In addition, the attachment of folded son is very delicate because any trace of fixation must be hidden which makes the so-called "cloisonné" technique very difficult and expensive to implement.
    Summary of the invention
    The object of the present invention is to overcome all or part of the disadvantages mentioned above by proposing a method of manufacturing a decorated article for a timepiece or jewelery allowing the very reproducible achievement of fine and complex decorations with a high-end rendering all drastically reducing the implementation time.

    Detailed Description of the Preferred Embodiments
    The invention has been developed for an article decorated for a timepiece such as a dial or a crown. Of course, the present invention can not be limited to the field of watchmaking. Other applications are also conceivable, such as, for example, jewelery or jewelery for cufflinks, earrings or pendants.
    Thus, in FIG. 1, we can see an example of a timepiece 1 whose dial 3 has most of the pitfalls that can be encountered. The dial 3 thus comprises a main surface P constituting the widest visible face.
    As shown in FIG. 1, the dial 3 may comprise a turn of hours 2 and / or a secondary display 4 formed by at least one index and / or at least one alphanumeric symbol.
    The dial 3 may also include a window 5, that is to say an opening of the dial 3 to show part of the movement 6 mounted under the dial 3, as a moon phase 7 in the example of fig. 1.
    According to the invention, the decorated article can form a wide variety of dressing parts or movement for a timepiece. By way of non-limiting examples, the decorated article can thus form all or part, in particular, of a case such as the middle part and the horns, a dial, a flange, a bezel, a pusher, a crown, a caseback, a needle, a bracelet such as a link, a wall, an oscillating weight, a bridge, an ice cream or a a clasp.
    The invention thus relates to a method of manufacturing a decorated article allowing the very reproducible achievement of fine and complex decorations with a high-end rendering all drastically reducing the implementation time.
    The method comprises a first step a) intended to form at least one recess of the shape of a future decoration in a visible surface of a substrate 11, 21, 31. It is thus clear that several types of substrate 11, 21, 31 are possible as well as several types of processes to form the recess (s).
    According to a first variant, the substrate 11, 21, 31 is made of metal or metal alloy. More specifically, the metal or metal alloy preferably comprises an iron alloy such as 15P, 20AP or 316L steel, a copper alloy such as brass, a nickel alloy such as nickel silver, titanium or an alloy thereof , gold or one of its alloys, silver or one of its alloys, platinum or one of its alloys, ruthenium or one of its alloys, rhodium or any of its alloys or palladium or one of its alloys its alloys.
    It is then understood that the substrate 11, 21, 31 is then formed for example by casting, sintering and / or machining. Preferably, an etching step, such as a laser etching or a chemical etching, is then carried out in order to completely form said at least one recess or to finish the formation of said at least one recess which may have been previously started during the first step. casting step, sintering and / or machining.
    According to a second variant, the substrate is based on silicon. More specifically, the silicon-based material preferably comprises monocrystalline silicon, doped monocrystalline silicon, polycrystalline silicon, doped polycrystalline silicon, porous silicon, silicon oxide, quartz, silica, lithium nitride and the like. silicon or silicon carbide.
    It is then understood that the substrate 11, 21, 31 is then formed for example by casting, stretching type Czochralski process and / or cutting. Preferably, an etching step, such as deep reactive ion etching (DRIE), laser etching or chemical etching, is then carried out in order to completely form said at least one recess or to finish the formation of said at least one recess which could be started beforehand during the casting step, stretching Czochralski type process and / or bucking.
    Finally, according to a third variant, the substrate 11, 21, 31 is ceramic. More specifically, the ceramic preferably comprises photostructurable glass, borosilicate, aluminosilicate, quartz glass, zerodur, monocrystalline corundum, polycrystalline corundum, alumina, aluminum oxide, nitride of aluminum, monocrystalline ruby, polycrystalline ruby, zirconium oxide, titanium oxide, titanium nitride, titanium carbide, tungsten nitride, tungsten carbide, boron nitride or boron carbide.
    It is then understood that the substrate 11, 21, 31 is then formed for example by casting, sintering and / or machining. Preferably, an etching step such as a deep reactive ion etching (DRIE), a laser etching, a chemical etching, is then carried out in order to totally form the said at least one recess or to finish the formation of the said at least one recess which has could be started in the casting, sintering and / or machining step. More specifically, the photostructurable glasses that can be used are for example available from Schott A.G. under the name Foturan®, from Hoya Corp. PEG3® or LifeBioScience Inc. under the brand name Apex ™.
    Advantageously according to the invention, whatever the variant used, the visible surface 32 of the substrate 11, 21, 31 may be both flat and curved to satisfy a wide variety of decorated articles. In addition, step a) is preferably performed with a laser to obtain a precise shape of said at least one recess. Preferably, the laser is short pulse, that is to say typically less than 100 picoseconds. However, a nanosecond laser, a picosecond laser or a femtosecond laser can be used interchangeably.
    It is also understood that during step a), said at least one recess can be formed with several funds at different depths to vary the light intensity reflected between said several funds as explained below.
    In addition, during step a), it is also possible to form a plurality of recesses, each bottom is identical, that is to say has the same uniform depth or not, or alternatively whose bottom enters at minus two recesses is not identical, that is to say does not have the same depth or has different funds.
    The method according to the invention comprises a second step b) intended to completely fill said at least one recess of a material at least partially transparent. It is understood that the object of the invention is therefore to provide a decorated article using the shape of said at least one recess and the nature of the substrate to form high-end decorations.
    Preferably, the at least partially transparent material is a polymer, a lacquer, a varnish or enamel. Thus, step b) may consist of a filling step in the liquid or pasty state of a precursor element of said material followed by a solidification or vitrification step, for example by adding light or heat energy, for filling said at least one recess of said at least partially transparent material.
    For example, if said at least partially transparent material is enamel, step b) may then comprise a first phase of filling said at least one recess with a precursor solution. the next layer of enamel, then a second phase of heating the room to transform the precursor solution into enamel. The precursor solution may for example be formed of particles, comprising enamel powder and, optionally, pigments for a predetermined coloration, which are suspended in a solvent such as oil.
    Finally, the process ends with step c) for removing any material from said visible surface 32 to leave said at least partially transparent material only in said at least one recess and form a visible surface 32 decorated without relief .
    We understand that a wide variety of decoration is possible. Thus, by way of example, during step a), at least one first recess and at least one second recess can be etched so that, during step b), said at least one first recess is filled with a first at least partially transparent material and said at least one second recess is filled with a second at least partially transparent material to provide two different types of decorations for the article. Such an article could for example form, in a first embodiment illustrated in FIG. 1, a decorated article forming a dial 3 of timepiece with a turn of hours 2 formed by said first at least partially transparent material and a secondary display 4 formed whose graduation is formed by said second at least partially transparent material.
    In addition, the method, according to an advantageous alternative, may also comprise, between step a) and step b), the optional step d) intended to engrave at least one guilloche on a bottom of said at least a recess for embellishing said upper visible surface decorated without relief. Indeed, such a step d) carried out, for example, by laser engraving or by chemical etching, makes it possible to distinguish through said at least partially transparent material an additional decoration.
    According to a second embodiment illustrated in FIG. 2, a decorated article 13 in the form of a tablet whose visible surface 12 is substantially flat and whose substrate 11 is formed of precious metal such as gold or platinum. The decorated article 13 which can for example be integrated into a timepiece or a cufflink, comprises a first decoration 10 formed by a substantially discoidal recess whose bottom is flat and filled with white enamel to represent for example a new moon. In addition, as shown in FIG. 2, the decorated article 13 comprises a second decoration 14 formed by a substantially discoidal recess whose bottom of uniform depth is engraved with a guilloche shaped face and filled with yellow enamel to represent for example the personified sun.
    The decorated article 13 further comprises a third series of decorations 16 formed by a star-shaped recess 17 whose bottom has a lower depth in the center than at the end of the arms of the star so that the center of each star appear brighter and filled with white or yellow lacquer to represent for example a starry night. The decorated article 13 further comprises a fourth series of decorations 18 formed by a first star-shaped recess 19 embedded in a second recess 20, each bottom of which is planar but at different depths, the depth of the second recess 20 being more weak than that of the first recess 19 so that it appears brighter. The second recess 20 is filled with a yellow enamel and the first recess 19 with a white enamel to represent for example a starry night. It can be seen that, advantageously, it is possible to form a very thin and complex star-shaped partition directly in the substrate 11 between the recesses 19 and 20, which is not possible to do, to the knowledge of the Applicant, with the so-called "cloisonné" technique.
    According to a third embodiment illustrated in FIG. 3, a disc-shaped decorated article 23 whose visible surface 22 is substantially curved, for example curved, and whose substrate 21 is made of ceramic such as white zirconia. The decorated article 23 which can for example be integrated into a timepiece or a cufflink, comprises a large decoration 24 formed by a substantially discoidal recess whose bottom has a first depth in the zone 25 and a second depth, less high first depth, for the rest of the recess. In addition, the whole bottom, whatever its depth, is engraved with a guilloche in the form of a celestial map. Finally the recess is filled with a blue varnish to represent for example a celestial sky with a deeper blue at the zone 25.
    FIG. 4 is a sectional representation of a decorated article 33 according to the invention to better understand the three embodiments above. Fig. 4 has a substrate 31 whose visible surface 32 is curved. Indeed, it can be seen that the thickness of the substrate 31 is less thick at the edges relative to the center, this section being able for example to come from a decorated article 33 in the form of a tablet.
    As shown in FIG. 4, a recess 35 filled with at least partially transparent material 36 can be seen. It is thus clear that the associated decoration will appear in a non-homogeneous visual rendition because the filling thickness of the material 36 is not constant like the third series of decorations 16 of FIG. 2.
    Alternatively or additionally, the bottom of the recess 37 can be as deep as that of the recess 35 and filled with a material 48 at least partially transparent different from that 36 to give a different rendering as between the recesses 19 and 20 of FIG. 2.
    Alternatively or additionally, the bottom of the recess 43 may be deeper than that of the recess 35 and filled with a material 44 at least partially transparent to reflect less light as between the recesses 19 and 20 of FIG. 2. It will thus be understood that the decoration associated with the recess 43 will appear in a darker visual rendering than the variable one of the recess 35 if the same filling material is used for the two recesses 35 and 43.
    Alternatively or additionally, the bottom of the same recess 45 may be at different depths 47, 48 and filled with a material 46 at least partially transparent. It is therefore understood that the associated decoration will appear in a non-homogeneous visual rendering because the filling thickness of the material 46 is not constant as the decoration 24 of FIG. 3.
    Finally, according to the advantageous alternative comprising the optional step d), in addition to the recess 39 or 49 filled with a material 40 or 50 at least partially transparent, a guilloche 41 or 51 may have been formed in the bottom of the recess 39 or 49 as the decoration 14 of FIG. 2.
    Of course, the present invention is not limited to the example shown but is susceptible of various variations and modifications that will occur to those skilled in the art. In particular, the process may comprise a final deposition step on the decorated article such as, for example, the deposition of a layer of silicon oxide, silicon nitride, silicon carbide or a carbon allotrope for tribological purposes. , thermic or visual of the dressing room. For example, the antireflection coating could be deposited on at least a portion of the decorated article.
