L'invention concerne encore un procédé de réalisation d'un tel mécanisme.The invention also relates to a method for producing such a mechanism.

L'invention concerne encore un procédé de transformation d'un tel mécanisme.The invention further relates to a method of transforming such a mechanism.

L'invention concerne le domaine des mécanismes horlogers comportant des composants en permanence en mouvement, et plus particulièrement le domaine des mécanismes d'échappement.The invention relates to the field of watch mechanisms comprising permanently moving components, and more particularly the field of escape mechanisms.

Arrière-plan de l'inventionBackground of the invention

Les constructeurs horlogers se sont toujours efforcés d'accroître la fiabilité des mouvements, grâce à la réduction de la fréquence des entretiens, tout en assurant la marche précise des mouvements horlogers.Watchmakers have always striven to increase the reliability of movements by reducing the frequency of interviews, while ensuring the precise movement of watch movements.

La lubrification des mobiles et composants en mouvement est un problème difficile à résoudre. De longues expérimentations tribologiques sont nécessaires pour mettre au point des solutions permettant de simplifier ou même de supprimer la lubrification.Lubrication of mobile and moving components is a difficult problem to solve. Long tribological experiments are needed to develop solutions to simplify or even eliminate lubrication.

Plus particulièrement, on recherche un fonctionnement sans lubrification des mécanismes d'échappement, en tentant de définir des couples de matériaux en frottement présentant un coefficient de frottement bas et stable ainsi qu'une faible usure, et présentant une excellente tenue dans la durée.More particularly, it seeks an operation without lubrication exhaust mechanisms, trying to define pairs of friction materials having a low coefficient of friction and stable and low wear, and having excellent durability.

Dans le cadre d'une utilisation de matériaux en frottement non-lubrifié dans l'échappement horloger, de récentes études tendent à montrer que le diamant CVD micro- ou nanocristallin en frottement contre lui-même conduit à un arrêt de l'échappement après un temps limité de fonctionnement. Cette problématique nécessite une lubrification suivie d'un entretien régulier à la manière d'un échappement classique acier/rubis.In the context of using non-lubricated friction materials in the watch exhaust, recent studies tend to show that diamond Micro- or nanocrystalline CVD in friction against itself leads to a stop of the exhaust after a limited time of operation. This problem requires lubrication followed by regular maintenance in the manner of a classic steel / ruby exhaust.

Description détaillée des modes de réalisation préférésDetailed Description of the Preferred Embodiments

L'invention concerne l'utilisation des matériaux contenant du bore, et plus particulièrement des céramiques au bore, en frottement non-lubrifié contre du diamant dans un mouvement horlogerThe invention relates to the use of materials containing boron, and more particularly boron ceramics, in non-lubricated friction against diamond in a watch movement.

L'invention consiste au remplacement de l'un des partenaires en frottement, habituellement diamant contre diamant, par un matériau comportant du bore, et plus particulièrement par une céramique contenant du bore. En particulier non-oxyde.The invention consists in replacing one of the friction partners, usually diamond against diamond, with a material comprising boron, and more particularly with a ceramic containing boron. In particular non-oxide.

Il est connu de l'homme de métier (tribologie non-lubrifiée du diamant) que des liaisons pendantes en surface peuvent amener à la création de liaison chimiques avec le partenaire en frottement, conduisant à un accroissement du coefficient de friction et éventuellement un collage, spécialement si l'autre partenaire est de même nature [ A. Erdemir, C. Donnet « Tribology of Diamond, Diamond-Like Carbon, and Related Films » ]. La passivation de ces liaisons pendantes peut résulter du milieu ambiant, humidité, gaz.It is known to those skilled in the art (non-lubricated diamond tribology) that dangling bonds on the surface can lead to the creation of chemical bonds with the friction partner, leading to an increase in the coefficient of friction and possibly a bonding, especially if the other partner is of the same nature [ A. Erdemir, C. Donnet "Diamond Tribology, Diamond-Like Carbon, and Related Films" ]. The passivation of these pendant bonds can result from the ambient environment, humidity, gas.

Dans le cas du frottement dans l'échappement du diamant CVD sur des surface de quelques dizaines de microns de largeur à de très faible force de contact (∼1mN), il semble que cette passivation par le milieu ambiant se produise difficilement, conduisant à une usure prononcée, à la formation de débris graphitiques, sp2, ce qui précipite le blocage de l'échappement par collage.In the case of the friction in the CVD diamond exhaust on surfaces of a few tens of microns in width to a very low contact force (~1mN), it seems that this passivation by the ambient medium occurs with difficulty, leading to a pronounced wear, the formation of graphitic debris, sp2, which precipitates the blockage of the exhaust by gluing.

Les mécanismes de frottement entre le diamant et d'autres matériaux sont très complexes.The friction mechanisms between diamond and other materials are very complex.

Toutefois, un partenaire en frottement avec le diamant, capable de procurer directement des atomes libres pour former des liens avec les liaisons pendantes du carbone, permettrait de favoriser cette passivation aux faibles forces de contact rencontrées dans le mouvement. Cette passivation évite l'apparition de collage.However, a diamond friction partner, capable of directly providing free atoms to form bonds with the carbon bonds, would promote this passivation at the low contact forces encountered in the movement. This passivation avoids the appearance of collage.

Des coefficients stables et bas ont été obtenus en frottement avec du diamant CVD microcristallin contre une céramique au bore nommée BAM (AlMgB14+TiB2, « NewTech Ceramics »).Stable and low coefficients were obtained in friction with microcrystalline CVD diamond against a boron ceramic named BAM (AlMgB14 + TiB2, "NewTech Ceramics").

Un bon comportement tribologique sans collage est également obtenu avec d'autres types de céramiques au bore en frottement contre du diamant monocristallin, microcristallin ou nanocristallin.Good tribological behavior without bonding is also obtained with other types of boron ceramics in friction against monocrystalline diamond, microcrystalline or nanocrystalline.

Typiquement des céramiques au bore telles que BAM peuvent être fabriquées en couches minces ou sous forme massive. Les méthodes de fabrication pour obtenir des céramiques en couches minces sont notamment, de manière non exhaustive : PVD (sputtering, pulsed laser déposition, etc), CVD, LPCVD, PECVD. La fabrication de céramiques massives se fait généralement par un procédé de frittage de poudre.Typically boron ceramics such as BAM can be manufactured in thin layers or in massive form. The manufacturing methods for obtaining ceramics in thin layers include but are not limited to: PVD (sputtering, pulsed laser deposition, etc.), CVD, LPCVD, PECVD. The manufacture of massive ceramics is generally done by a process of sintering powder.
