Abstract (en)
The method involves providing a metal base plate (10) in a form of a section (11) made of a first material comprising titanium or/and titanium alloy
and a metallic covering plate (20) made of a material comprising a metal selected from gold, platinum and palladium or/and an alloy comprising
gold or platinum or palladium, where the plate has thickness (E) greater than or equal to 0.5 mm. The covering plate is soldered on the base plate
in order to form a bi-metal blank. The blank is designed and/or machined to provide a final shape to a bi-metal clock covering component (100). An
independent claim is also included for a bi-metal clock covering component.
Abstract (fr)
Procédé de fabrication d'un composant d'habillage (100) d'horlogerie comprenant les étaps suivantes : - on se munit d'une embase (10) métallique
réalisée en un premier matériau comportant du titane ou/et un premier alliage de titane, - on se munit d'une plaque de recouvrement (20) métallique
réalisée dans un deuxième matériau, ledit deuxième matériau comportant un deuxième métal choisi parmi l'or et le platine et le palladium ou/et un
deuxième alliage comportant au moins de l'or ou du platine ou du palladium, ladite plaque de recouvrement (20) étant d'une épaisseur supérieure
ou égale à 0,5 millimètre ; - on soude ladite plaque de recouvrement (20) sur ladite embase (10) de façon à former une ébauche bi-métallique (30); on conforme ou/et on usine ladite ébauche bi-métallique (30) pour donner audit composant de structure (100) sa forme finale.
