Definitions
- the invention relates to a timepiece component comprising at least one self-lubricating surface layer.
- the invention also relates to a clock escapement mechanism comprising at least one such component.
- the invention also relates to a watch movement comprising at least one such escape mechanism.
- the invention further relates to a watch having at least one movement.
- the invention further relates to a method of coating a timepiece component with a self-lubricating surface layer.
- the invention relates to the field of watch mechanism components subjected to intense use, with a high pulse frequency, and a large number of pulses and friction phases during their service, such as exhaust mechanism components.
- the porous metal comprises copper, tin and graphite, and may contain a solid lubricant such as boric acid or salicylic acid, useful in particular during pressing or sintering.
- Boric acid H 3 BO 3 is of particular interest in friction because of its ability to lubricate dry. During friction, the planar crystalline meshes of boric acid tend to self-level into sheets parallel to the surface. This arrangement reduces friction similarly to more well known compounds such as MoS 2 molybdenum sulphide and WS 2 tungsten sulphide.
- the invention aims at a non-lubricated operation of the watch exhaust, in order to reduce maintenance, and to allow high oscillation frequencies.
- the invention relates to a timepiece component comprising at least one self-lubricating surface layer, according to claim 1.
- the invention also relates to a clock escapement mechanism comprising at least one such component.
- the invention also relates to a watch movement comprising at least one such escape mechanism.
- the invention further relates to a watch having at least one movement.
- the invention further relates to a method of coating a timepiece component with a self-lubricating surface layer according to claim 12.
- the invention proposes, at least for the most stressed components of watchmaking mechanisms, to produce them with a dry, self-lubricating surface layer, for which the use of boric acid H 3 BO 3 is preferred, which is of particular interest in friction, because of its ability to lubricate dry.
- the invention relates to a timepiece component 1 comprising at least one self-lubricating surface layer 2.
- this surface layer 2 is a dry layer comprising boric acid H 3 BO 3 and has a thickness of between 10 nanometers and 10 microns.
- this thickness is between 50 nanometers and 1 micrometer.
- this surface layer 2 consists entirely of boric acid.
- the component 1 comprises, under this surface layer 2, a material chosen to provide a very good adhesion of boric acid.
- the component 1 comprises, under the surface layer 2, a substrate which is either composed of silicon oxide SiO 2 or aluminum oxide Al 2 O 3 , or which is covered with a layer intermediate 3 consisting of silicon oxide SiO 2 or Al 2 O 3 aluminum oxide, or DLC, or the like.
- a component 1 which is an escape mechanism component, taken from an escape wheel, an anchor, a rocker, a dart, an ellipse, a pallet, a stop of limitation, a plateau, a quill, a rest, a relaxation, a fork, an ankle.
- the invention also relates to a clock escapement mechanism comprising at least one such component 1.
- this escapement mechanism 10 comprises such a component 1 which is an escape wheel made of silicon oxide or a mixture of silicon and silicon oxide SiO 2 .
- the component 1 is made of silicon by DRIE, and then thermally oxidized.
- the micro-manufacturing of silica or quartz components (crystalline or amorphous SiO 2 ) is not yet completely controlled at present.
- This escape wheel is coated with such a superficial layer 2 of boric acid, and is arranged to cooperate with other components 1 which are ruby paddles each coated with such a surface layer 2 of boric acid.
- the invention also relates to a watch movement 100 comprising at least one such escape mechanism 10.
- the invention also relates to a watch 1000 comprising at least one such movement 100.
- the invention also relates to a method of coating a timepiece component 1 with a self-lubricating surface layer 2.
- the thickness of the boric acid layer H 3 BO 3 can also be controlled by the concentration of the solution.
- the thickness therefore also depends on the concentration of the solution.
- the repetition of the steps makes it possible to increase the thickness, because the dissolution of the boric acid already formed is relatively slow.
- this method is applied to a watch exhaust mechanism component 1, emitting or undergoing more than one pulse per second, chosen from an escapement wheel, an anchor, a pendulum, a dart, a ellipse, a palette, a limit stop, a plateau, a star, a rest, a relaxation, a fork, an ankle.
- the thickness of the boric acid layer is between 50 nanometers and 1 micrometer.
- the components to be coated with boric acid are typically silicon, silicon and silicon oxide, metals or ceramics. These may have a rough or porous surface, so as to promote adhesion.
- the typical concentration of the solution is calculated so as to coat the components with a thin layer, more particularly of the order of 100 nm, of solid boric acid.
- the solubility of the H 3 BO 3 at room temperature being, in the solvent liquids proposed above, higher than the recommended dosage, it is generally not necessary to heat the liquids. However, heating can facilitate dissolution, especially in the case of water that is not flammable.
- H 3 BO 3 powder is advantageously mixed with the solvent and stirred, and ultrasound may also be used.
- the component to be coated is soaked in the solution, or sprinkled, then extracted and allowed to dry, so as to avoid contact with the functional parts, for example deposited on a blotting paper.
- a slight gas blast may be used to hasten the evaporation of the liquid.
- the component 1 In its final state, the component 1 is covered with the desired surface layer 2.
- the component 1 is made to have a mirror-polished surface before coating, interference fringes are visible.
- the small thicknesses of deposited boric acid typically from about 50 nm to 100 nm, do not bring about a marked color change.
- the passage of a sharp object on the surface may leave a trace indicative of the presence of the layer.
- the invention allows a non-lubricated operation of a watch exhaust, to reduce maintenance, and allow high oscillation frequencies.
