Embodiment Construction

[0021] figure 1 A micromechanical component 10 for a timepiece mechanism according to one embodiment is schematically shown. Part 10 comprises at least one contact surface 100, at least a part of which is intended to make a sliding and / or pivoting contact, for example with another part of a timepiece mechanism.

[0022] Part 10 is made wholly or partly from carbon or aluminum oxide (Al 2 o 3 ) composed of crystalline mineral materials. Preferably, the crystalline mineral material is natural or synthetic diamond, ruby, or sapphire. Other materials are also possible, such as polymers, metals or metal alloys, ceramics, silica, glass, silicon, and the like.

[0023] The component 10 consisting entirely or partially of crystalline mineral material comprises a contact surface 100 which partially comprises at least one microstructured region 110 . The microstructured region 110 may be more oleophobic than the non-microstructured contact surface 100 . Alternatively, the microstr...

Abstract

A micromechanical component (10) intended for clock mechanisms, wherein at least one portion of the component consists of a crystalline mineral material with a carbon or alumina basis and comprises at least one contact surface (100) intended to be brought into sliding and / or pivoting contact; the contact surface (100) locally comprising at least one microstructured area (101) having a three-dimensional texture; the three-dimensional texture being formed of microcavities (20), making the microstructured area (110) more oleophobic than the non-microstructured contact surface (100), and / or formed of micro pillars (30) making the microstructured area (110) more oleophilic than the non-microstructured contact surface (100); the microstructured area (110) being configured to locally confine a lubricant substance to a lubricated portion (120) of the contact surface (100).

Description

technical field [0001] The invention relates to a micromechanical component for a timepiece mechanism, in particular a component to be lubricated. Background technique [0002] It is known that in a clockwork there are many parts which are in motion and are in frictional contact with each other. These frictions must be reduced as much as possible, since they can affect the precision and / or autonomy of the mechanism. Therefore, in order to reduce these frictions, it is known to use liquid lubricants or viscous lubricants. Use this lubricant sparingly on well-defined areas and in the proper amount. [0003] However, this lubricant may escape from the area where it was deposited. In particular, movement of parts tends to displace lubricant from contact areas to areas not subjected to friction in the natural chemical state of surfaces resulting from exposure to environmental conditions. Furthermore, it is difficult to form a lubricating film only at a specific area on a smal...
