发明名称 Timepiece escapement mechanism without lubrication
摘要 A timepiece escapement mechanism with improved tribology includes 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. 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. The first friction surface is formed by a surface of a solid element which is made of solid silicon nitride in a stoichiometric formulation Si3N4. A method for making the escapement mechanism is also provided.

主权项 1. A timepiece escapement mechanism with improved tribology, comprising: at least one pair of separate components including a first component and a second component respectively including a first friction surface on the first component and a second friction surface on the second component, the first friction surface and the second friction surface are ranged to cooperate in frictional 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 a surface of a solid element which is made of solid silicon nitride in a stoichiometric formulation Si3N4.
