A method for manufacturing a silicon timepiece component () with a functional external profile.

Method for manufacturing a silicon balance spring

The invention relates to a method for bonding timepiece components, comprising applying an adhesive to a first and/or second timepiece component to be bonded to one another, and depositing an adhesion layer onto at least one of the first and second components to be bonded by spraying a primer composition in a localised joining area followed by the solidification of the primer composition. The adhesion layer is deposited prior to the application of the adhesive if the adhesive is applied to the one or more same components as the adhesion layer.

A method for manufacturing a spiral spring may include: (a) providing a blank with an Nb—Ti core; (b) beta-quenching the blank; (c) deforming the blank in several sequences; (d) winding to form the spiral spring; (e) final heat treatment on the spiral spring. The blank in (a) may include a layer of X including Cu, Sn, Fe, Pt, Pd, Rh, Al, Au, Ni, Ag, Co and Cr or an alloy of one of these elements around the Nb—Ti core. The method may include heat treating to partially transform the layer of X into a layer of X, Ti intermetals around the Nb—Ti core, and may be carried out between (b) and (c) or between two sequences of (c). The method may include removing the part of the layer of X, which may be carried out between (b) and (c), between two sequences of (c) or between (c) and (d).
