Abstract (en)
[origin: US2018173165A1] A pivot arbor for a timepiece movement including at least one pivot made of a non-magnetic metal material at at least one of its ends in order to limit its sensitivity to magnetic fields. The non-magnetic metal material is a non-magnetic light metal or a non-magnetic alloy of the light metal, and at least the external surface of the pivot is coated with an anodic oxide layer of the material, obtained by anodic growth.
Abstract (fr)
L'invention se rapporte à un axe de pivotement pour mouvement horloger comportant au moins un pivot (3) en un matériau métallique amagnétique (4) à au moins une de ses extrémités afin de limiter sa sensibilité aux champs magnétiques. Ledit matériau métallique amagnétique (4) est un métal léger amagnétique ou un alliage amagnétique dudit métal léger, et au moins la surface externe dudit pivot (3) est recouverte d'une couche anodique d'oxyde dudit matériau (5), obtenue par croissance par anodisation. L'invention concerne le domaine des mouvements d'horlogerie.
