Definitions
- the invention relates to a component at least partially coated with black.
- This component is intended for the interior trim or the movement of a timepiece or piece of jewelry. It also relates to the method of manufacturing said component.
- the black “color” can be obtained in the mass of a material by its intrinsic color or via the addition of pigments or dyes within the material.
- the black “color” may also be present only on the surface.
- This surface coloring can be obtained in different ways, generally by oxidation/sulfidation/carburization of a metal substrate or by depositing an oxide/sulfide/carbide on a substrate.
- Carbon is therefore a well-known element for blackening a surface.
- Document EP 3 327 517 discloses a dial with a first substrate coated with a black layer of nanotubes facing the watch glass and with a second substrate attached to the first substrate on the surface opposite the glass.
- the first substrate is perforated in order to produce openings acting as windows intended to form indexes.
- the second substrate includes a luminescent coating at least in the zones opposite the openings so as to create a contrast at the level of the first substrate between the black layer and the illuminated indexes.
- the contrast is obtained via the superposition of two substrates having distinct coatings.
- This superposition makes it possible to avoid selectively depositing one and the other coating on the same surface and to manipulate the layer of nanotubes, which is particularly fragile, more than necessary.
- This superposition nevertheless has the drawback of requiring the manufacture of two substrates, which increases the production costs.
- these ultra-black absorbent deposits are formed from a forest of vertically growing carbon nanotubes using a chemical vapor deposition method.
- the majority of carbon nanotubes should be deposited in a controlled orientation and perpendicular to the substrate.
- This process applied directly to watch parts is complex to implement.
- paints or varnishes based on carbon nanotubes can be applied by spraying. This second process is easier to implement but gives less deep blacks.
- the application and use of carbon nanotubes is complex to implement and can present potential dangers in terms of safety during the manufacture of coatings, the assembly of watch parts and operations.
- the forest structure of the coating based on carbon nanotubes makes it very fragile and difficult to handle. These coatings have very low mechanical strength and are easily crushed even under the effect of slight mechanical pressure. The layer can be so friable that it is almost impossible to touch it without degrading the surface, showing shiny veils or even holes contrasting with the original color of the carbon nanotubes.
- the forest structure of the coating does not allow the surface application of an overlying decoration by usual direct printing techniques.
- the present invention aims to overcome the drawbacks of coatings based on carbon nanotubes by proposing another type of ultra-absorbent black coating, more resistant and more compact to allow the usual operations of manipulation and decoration in the field of watches or jewellery.
- the black coating comprises a metal oxide and in particular aluminum oxide deposited by processes of the PVD, CVD or PECVD type.
- This ultra-black decorative coating has the characteristics of having:
- micrometric thickness allowing the enhancement of parts having a complex surface geometry and/or a characteristic horological decoration
- the present invention relates to the component at least partially coated with this black coating as well as to the method of manufacturing said component.
- FIG. 1 is a plan representation of a timepiece provided with a dial coated and decorated according to the method of the invention.
- FIGS 2A to 6 are schematic representations of different embodiments of the method according to the invention with the successive steps implemented.
- the invention relates to a component intended for the interior trim or the movement of a timepiece or piece of jewelry. It can be chosen from the non-exhaustive list comprising a dial, flange, hand, index, applique, oscillating weight, plate, bridge, etc. According to the invention, this component is at least partially coated with a black layer. As described below, the invention also relates to an assembly of two of said components at least partially coated with the black layer.
- the black layer is a layer mainly comprising aluminum oxides AlxOy such as A ⁇ Os with, in addition, non-ferrous metal oxides such as, for example, oxides of copper, zinc, nickel, chromium, silver or manganese.
- This layer comprises at least 90% AlxOy, preferably 100% AlxOy.
- the aluminum oxide has an aluminum content of between 45% and 65% by mass and preferably between 45% and 50% by mass.
- This layer has a thickness of between 1 and 50 microns, preferably between 2 and 10 microns, and more preferably between 4 and 7 microns. It can be deposited by PVD (for Physical Vapor Deposition in English), CVD (for Chemical Vapor Deposition in English) or PECVD (for Plasma-Enhanced Chemical Vapor Deposition in English).
- the ultra-absorbent black deposits according to the invention have reflectance values in the visible range of less than 2% and more particularly less than 1.5% as shown in Table 1 for coating thicknesses of between 4 and 7 microns. .
- the measurements are Total Hemispherical Reflectance (THR) measurements obtained by light absorption spectrometry.
- the black coating has a compact microstructure. This compact structure allows the application of decorations without damaging the black coating.
- the decorations can be of any kind. They may be indexes, possibly photoluminescent, stones 4 crimped or glued onto the substrate 2 as shown in FIG. 1, elements made of metallic material, resin, composite material, wood, mother-of-pearl, etc. . It can also be luminescent elements such as LEDs.
- the decorations are made or added onto the black coating or onto portions of the substrate that have no black coating. These portions may be devoid of the black coating from the outset or the coating may be selectively removed by mechanical machining techniques, laser or by ion or electronic bombardment, for functional or aesthetic reasons. Pulsed type lasers and in particular picosecond, nanosecond or femtosecond type lasers are chosen for the selective ablation of the black coating.
- the decorations can be built on the substrate by printing methods such as pad printing, digital printing or additive manufacturing. They can also be constructed by electroforming or by "hot forming" of amorphous metals, for the variants where the decoration is produced on portions not coated with the black layer, directly on the metal substrate.
- the decorations can also be added by gluing.
- the decoration can also be placed under a discontinuous layer of the black coating.
- the component comprises a decoration on the surface of the substrate such as a metallic coating, a resin or a lacquer, including a photoluminescent lacquer.
- the black coating is applied to the decor and selectively removed at places chosen to make the decor appear and thus create a contrasting decor.
- another decor can be constructed or attached to the black coating.
- the present invention also relates to an assembly comprising a first component and a second component each intended for the interior trim or the movement of a timepiece or piece of jewelry.
- the first and the second components comprise at least one portion coated with the black layer.
- the first component has a relative movement with respect to the second component and is mounted facing the latter.
- This first component is decorated.
- the first component is a hand coated with the black layer and decorated
- the second component is a dial coated with the black layer.
- the needle is decorated with a stone set or glued to the end of the needle.
- the component manufacturing process includes at least:
- the substrate 2 may have a structure in relief at the end of the machining
- the substrate can undergo a microsandblasting or microbeading pretreatment in order to increase the surface roughness (step not shown).
- the surfaces thus treated have a roughness Ra (arithmetic mean roughness) measured with an Altisurf 500 optical profilometer (ISO 4288:1996/4287:1997) of between 0.4 and 5 microns and preferably between 0.4 and 2 microns.
- the substrate can undergo an electrolytic oxidation pretreatment of the anodization or ceramization type by electrolytic plasma in order to give a black and rough appearance to the surface of the part (step not shown).
- the substrate is preferably made of a titanium alloy, e.g.
- the substrate is subjected to vacuum treatment in order to deposit the ultra-black coating on the surface.
- Step b) can consist of a step of depositing the black layer on the substrate by PVD, CVD or PECVD.
- the black layer is deposited by PVD, CVD or PECVD on a thin support of film or tape type and then bonded to the substrate (glue or adhesive layer 5 in FIG. 5).
- the film or strip can be made of a polymer or metallic material comprising on its face opposite the coating the adhesive intended to be fixed to the substrate.
- the manufacturing process may also include a step c) of decoration before and/or after step b).
- the decoration step may consist of building a decoration on the coated portion or on an uncoated portion by the printing method or by electroforming.
- the decorating step can also consist in applying the decor to the coated or uncoated portion, the decor being able to be fixed, for example by gluing.
- step c) of decoration subsequent to the deposition of the black layer 3 in stage b).
- This decoration step c) can be preceded by a step d) of selective removal of the black layer 3 on the areas intended to be decorated in step c) as illustrated in FIGS. 4A, 4B and 6.
- This selective removal can be limited to the black layer 3 (fig.4A and fig.6) or extend into the substrate 2 (fig.4B).
- the method may comprise a step c) of decoration before step b) of depositing the black layer 3 as illustrated in FIG. 6.
- the substrate is machined and decorated with a first decoration 4.
- the decorated substrate is then coated with black layer 3 in step b).
- the black layer 3 is selectively removed in step d) to make the first decoration 4 visible on certain portions.
- the manufacturing process may include a second stage c) of decoration on the portions comprising the black layer 3.
- the second decoration 4 only partially covers the black layer 3.
- the method can also include an additional step (not shown) of depositing on the black layer, with or without decoration, a hard protective coating.
- This coating is a transparent coating of the ALD (Atomic Layer Deposition) type based on a metal oxide such as TiC, Al2C>3, SiO2 or a mixture of at least two of these oxides.
- This hard coating has a thickness of between 5 and 100 nm, preferably between 5 and 20 nm.
