Description Description
Domaine de l’invention Field of the invention
[0001 ] L’invention se rapporte à un procédé de fabrication d’une céramique mate et, plus particulièrement, à une telle céramique non marquante. The invention relates to a method of manufacturing a matte ceramic and, more particularly, to such a non-marking ceramic.
Arrière plan de l’invention Background of the invention
[0002] Il est connu de fabriquer des pièces en céramique mate pour diversifier leur esthétique. Toutefois, il s’est avéré que de telles pièces perdent leur attrait premier de pièces inrayables en laissant parfois apparaître des marques. It is known to manufacture matt ceramic parts to diversify their aesthetics. However, it turned out that such pieces lose their first attraction of scratchproof parts, sometimes leaving marks.
Résumé de l’invention Summary of the invention
[0003] Le but de la présente invention est de pallier tout ou partie les inconvénients cités précédemment en proposant un procédé de fabrication d’une pièce céramique mate qui garde son esthétique avantageuse tout en gardant leur attrait d’être inrayable. The object of the present invention is to overcome all or part of the disadvantages mentioned above by proposing a method of manufacturing a matte ceramic piece that keeps its attractive aesthetic while keeping their attractiveness to be scratchproof.
[0004] A cet effet, l’invention se rapporte à un procédé de fabrication d’une pièce céramique mate comportant les étapes suivantes: a) fabriquer une pièce céramique; b) sabler des parties de la pièce céramique afin de les rendre mates; caractérisé en ce qu’il comporte l’étape finale suivante: c) roder les parties mates afin d’écrêter l’état de surface des parties mates. For this purpose, the invention relates to a method of manufacturing a matte ceramic part comprising the following steps: a) fabricating a ceramic part; b) sandblasting parts of the ceramic piece to make them matt; characterized in that it comprises the following final step: c) honing the matte parts in order to trim the surface finish of the matt parts.
[0005] On comprend donc, avantageusement selon l’invention, que les objets qui rencontreront la pièce en céramique mate, ne seront plus griffés mais glisseront sur les zones aplanies en évitant donc que les anfractuosités de l’état de surface ne se bouchent en laissant des traces. De plus, la céramique conserve avantageusement l’aspect mat recherché. It is therefore understood, advantageously according to the invention, that the objects that will meet the matte ceramic part, will not be scratched but will slide on the flattened areas, thus avoiding that the crevices of the surface state will become clogged. leaving traces. In addition, the ceramic advantageously retains the desired matte appearance.
[0006] Conformément à d’autres caractéristiques avantageuses de l’invention: According to other advantageous features of the invention:
- le procédé comprend, entre l’étape a) et l’étape b), l’étape d): polir la pièce céramique afin de mieux maîtriser la rugosité des parties mates obtenues lors de l’étape b); the process comprises, between step a) and step b), step d): polishing the ceramic part in order to better control the roughness of the matt parts obtained during step b);
- l’étape d) est obtenue par trovalisation; step d) is obtained by trovalisation;
- lors de l’étape d), la rugosité Ra obtenue est inférieure à 20 nm; during step d), the roughness Ra obtained is less than 20 nm;
- l’étape a) est obtenue par frittage; step a) is obtained by sintering;
- l’étape b) est obtenue par projection de particules de corindon; step b) is obtained by spraying particles of corundum;
- l’étape c) est obtenue par tonnelage; step c) is obtained by tumbling;
- le rodage obtenu par l’étape c) est compris entre 0,8 pm et 2 pm. the break-in obtained by step c) is between 0.8 μm and 2 μm.
[0007] L’invention se rapporte également à une pièce d’horlogerie caractérisée en ce qu’elle comporte au moins une pièce céramique mate obtenue selon l’une des variantes du procédé ci-dessus. The invention also relates to a timepiece characterized in that it comprises at least one matte ceramic piece obtained according to one of the variants of the above method.

Description détaillée des modes de réalisation préférés Detailed Description of the Preferred Embodiments
[0010] La fig. 1 présente une pièce d’horlogerie 1 1 qui peut comporter au moins une pièce céramique mate obtenue selon les modes de réalisation du procédé 1 expliqué ci-dessous. Ainsi, la pièce céramique mate peut former des éléments de l’habillage de la pièce d’horlogerie 1 1 comme, de manière non limitative, la boîte 13, la lunette 15, les moyens de commande 17 et/ou le bracelet 19 comportant notamment des maillons 14. FIG. 1 shows a timepiece January 1 which may comprise at least one matte ceramic piece obtained according to the embodiments of method 1 explained below. Thus, the matt ceramic piece can form elements of the cladding of the timepiece 1 1, such as, without limitation, the box 13, the bezel 15, the control means 17 and / or the bracelet 19 comprising in particular links 14.
[0011 ] Tous ces éléments au porté de l’utilisateur peuvent entrer en contact avec les objets du quotidien. Après analyse, il a été remarqué qu’une pièce en céramique mate est toujours inrayable mais la rugosité, engendrée par l’aspect mat souhaité, gratte tous les objets avec lesquelles la pièce entre en contact. Ainsi, la majorité des objets rencontrés étant faits All these items worn by the user can come into contact with everyday objects. After analysis, it has been noticed that a matt ceramic part is always scratchproof but the roughness, generated by the desired matte aspect, scratches all the objects with which the piece comes into contact. Thus, the majority of objects encountered being made
