Definitions

  • the invention relates to a cladding component for a timepiece or jewelery, made of a precious precious alloy based on titanium.
  • the invention also relates to a timepiece or jewelery comprising at least one such dressing component.
  • the invention relates to the field of timepieces for clocks, jewelery, or jewelry.
  • a characteristic common to most precious alloys used in watchmaking is their relatively high density (> 10 g / cm 3 ). Indeed, the two main precious metals used in watchmaking, namely gold and platinum, have respective densities of about 19.3 and 21.5 g / cm 3 . This has the consequence of making their alloys relatively heavy. Silver and palladium are lighter (10.5 and 12 g / cm 3 respectively) but much less used in watchmaking.
  • WO 2012/119647 A1 describes ceramic-precious metal composites that can reach relatively low densities ( ⁇ 8 g / cm 3 ).
  • the equi-atomic Ti phases (Pd / Pt / Au). Indeed, these phases may be similar to the TiNi equi-atomic phase used in some shape memory alloys.
  • the TiPd, TiPt and TiAu equi-atomic phases have a certain ductility and can, under certain conditions, present behaviors typical of TiNi shape memory alloys.
  • the TiPd, TiPt and TiAu equi-atomic alloys have been known for a long time and have been the subject of several studies involving high-temperature shape-memory alloys.
  • TiPd and TiAu alloys are titrable and therefore of interest for watchmaking and jewelery as particularly precious precious metals.
  • the invention proposes to make watchmaking components, both valuable to benefit the title and the resistance over time and corrosion, and lighter than known alloys.

  • the invention also relates to a timepiece or jewelery comprising at least one such dressing component.
  • the invention is concerned with the replacement of gold and palladium in titanium-based alloys.
  • the invention relates to a dressing component 1 of watches or jewelery (including jewelery) precious alloy light titanium base, and any timepiece or jewelry including such a component.
  • alloys as described above in Table 1, which are overloaded with precious metal with respect to the titles to which they can be punched, generates an unnecessary extra cost.

  • the elements of a fourth group comprising: Al, Si, Ge, Sn, Sb and In can be introduced in small quantities ( ⁇ 4 at%) in TiPd and TiAu alloys in place of titanium or palladium and gold, respectively.
  • substitute materials should not generate health risks.
  • the substitute materials of the latter must not be valuable.
  • the substitute materials in order not to overload the alloy, the substitute materials, ideally, are not heavier than the substituted metal.
  • a particularly advantageous embodiment of the invention relates to the substitution of a part of the palladium in a TiPd alloy.
  • the invention thus relates to a ductile alloy based on the Ti-Pd equi-atomic intermetallic, in which the excess of palladium relative to the mass content of Pd500 is partially or totally replaced by a non-precious element, so that the titanium still represents 50 atomic% of the final alloy.
  • a ductile alloy based on the Ti-Pd equi-atomic intermetallic, in which the excess of palladium relative to the mass content of Pd500 is partially or totally replaced by a non-precious element, so that the titanium still represents 50 atomic% of the final alloy.
  • Such an alloy has sufficient ductility to provide a formability similar to that of conventional titanium alloys.
  • TiPdFe and TiPdNb ternary alloys make it possible to attain the desired title.
