TIMEPIECE ESCAPEMENT MECHANISM WITHOUT LUBRICATION |
| 摘要 |
Timepiece escapement mechanism with improved tribology, including a first component and a second component respectively including a first friction surface and a second friction surface arranged to cooperate in contact with each other, wherein the second friction surface includes at least one silicon-based material taken from a group including silicon, silicon dioxide, amorphous silicon, polycrystalline silicon, porous silicon, or a mixture of silicon and silicon oxide, and wherein the first friction surface is formed by the surface of a solid element which is made of solid silicon nitride in the stoichiometric formulation Si3N4. |

1. A timepiece escapement mechanism with improved tribology, including at least one pair of components including a first component and a second component respectively including a first friction surface and a second friction surface which are arranged to cooperate in contact with each other, wherein said second friction surface includes at least one silicon-based material taken from a group including silicon, silicon dioxide, amorphous silicon, polycrystalline silicon, porous silicon, or a mixture of silicon and silicon oxide, and wherein said first friction surface is formed by the surface of a solid element which is made of solid silicon nitride in the stoichiometric formulation Si3N4. |
