Abstract (en)
The pivot pin (1) includes at least one pivot (3) at at least one of the ends of the pivot pin. The pivot is formed of a composite material having a metallic matrix including at least one metal selected from among nickel, titanium, chromium, zirconium, silver, gold, platinum, silicon, molybdenum, aluminum or an alloy of the above metals. The matrix is charged with hard particles selected from among tungsten carbide, titanium carbide, tantalum carbide, titanium nitride, titanium carbonitride, aluminum oxide, zirconium oxide, chromium oxide, silicon carbide, molybdenum silicide, aluminum nitride or their combination, so as to limit the sensitivity of the pin to magnetic fields.
Abstract (fr)
L'invention se rapporte à un axe de pivotement pour mouvement horloger (1) comportant au moins un pivot à au moins une de ses extrémités, caractérisé en ce que ledit au moins un pivot est formé d'un matériau composite ayant une matrice métallique comprenant au moins un métal choisi parmi le nickel, le titane, le chrome, le zirconium, l'argent, l'or, le platine, le silicium, le molybdène, l'aluminium ou un alliage de ces derniers, ladite matrice étant chargée de particules dures choisies parmi, WC, TiC, TaC, TiN, TiCN, Al2O3, ZrO2, Cr2O3, SiC, MoSi2, Al N ou une combinaison de ces derniers, afin de limiter la sensibilité de l'axe aux champs magnétiques L'invention concerne le domaine des mouvements d'horlogerie.
