More Information
Summary:A timepiece mechanism including a pair of components with a first component including a material taken from a first group including solid monocrystalline, natural diamond, micro- or nano-crystalline CVD diamond, solid monocrystalline diamond, and amorphous carbon "DLC", and having a first friction surface arranged to cooperate with a second friction surface included in a second opposing component and the second component includes, at least in its second friction surface, a material with a high concentration of boron, greater than 10 atomic percent, and, in a particular embodiment, this second opposing component includes at least one ceramic containing boron. Method for manufacturing such a mechanism. Method for transforming such a mechanism.
