Company patents

Comadur SA

Comadur SA's patent strategy reveals a surprising shift away from several core manufacturing and materials categories, with significant year-over-year declines in areas like Coating & Surface Treatment (-100.0% so far in 2026), Plastics Shaping & Molding (-100.0% so far in 2026), and Powder Metallurgy (-50.0% so far in 2026), despite these categories previously representing substantial portions of their portfolio.

Method for brazing titanium alloy components with zirconia-based ceramic components for horology or jewellery

Filed:2019-11-11Pub:2022-11-15
Applicant:Comadur SA

A method for brazing a first ceramic component and a second metal alloy component, to make a structural or external timepiece element, a zirconia-based ceramic is chosen for the first component and a titanium alloy for the second component, a first recess is made inside the first component, set back from a first surface in a junction area with a second surface of the second component, braze material is deposited on this first surface and inside each recess, the second surface is positioned in alignment with the first surface to form an assembly, this assembly is heated in a controlled atmosphere to above the melting temperature of the braze material, in order to form the braze in the junction area.
