Definitions
- the invention relates to a cladding component for a timepiece or jewelery, made of precious alloy light comprising 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 2012/1 19647 A1 describes ceramic-precious metal composites that can reach relatively low densities ( ⁇ 8 g / cm 3 ).
- 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 document EP0267318 in the name of HAFNER mentions certain palladium alloys: from 25 to 50% by weight of palladium, with from 37 to 69% of silver, and a complement of copper, zinc, gallium, cobalt, indium, tin, iron, aluminum, nickel, germanium, rhenium, but without titanium, and other alloys, from 51 to 95% of palladium, with contributions of different metals, of which only one alloy comprises gold, with mass 70% palladium, 15% silver, 5% copper, 5% zinc, 3% platinum, 2% gold.
- the only composition disclosed with titanium, Ti 5 Pd 95 type relates to an alloy with 5% titanium, and 95% palladium.
- the document EP0239747 in the name of SUMITOMO describes the addition of 0.001 to 20% of chromium to a titanium-palladium type alloy with 40 to 60 atomic% of titanium, the balance being made on palladium.
- the disclosures relate to seven alloys at 50 atomic% titanium, with 40 to 50 atomic% palladium, and 0 to 10 atomic% chromium: Ti 50 Pd 4 o, Ti 5 oPd 45 C r 5, Ti 5 oPd 43 Cr7 , T550Pd 42 Cr8, T5dPd 4 i .5Cr8.5, T5dPd 4 iCrg, T5dPd 4 oCrio-
- 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 relates to a dressing component for timepiece or jewelery, according to claim 1.
- the invention also relates to a timepiece or jewelery comprising at least one such dressing component.
- FIG. 1 compares the stress-strain curves of alloys tested in compression with a strain rate of 0.001 / s:
- FIG. 2 shows a watch comprising a box and a bracelet according to the invention.
- the invention is concerned with the replacement of gold and palladium in alloys comprising titanium.
- the invention relates to a dressing component 1 of watchmaking or jewelery (including jewelery) precious alloy light comprising titanium, and any timepiece or jewelery comprising such a component.
- the invention relates to two families of alloys, described successively.
- the first family of alloys describes nine type compositions (first to ninth), using five groups of metals (first to seventh) and some of their subgroups.
- 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.
- advantageous substitutes may be suitable for the overloading of precious metal, and in particular the metals of a second group comprising: Fe, Co, Ni, Ru, Rh, Ir, Au, Pt, Nb, V, Mo , Ta, W.
- the compression ductility alloys Ti 5 OPD 5.5Nbi4.5 3, Ti 5 OPD 2Fei8 3 and Ti 4 4.5Pd35Nbi i 9 .5 Fe (at.%) Is not significantly different from that of an alloy Equi-atomic binary TiPd, as visible in Figure 1, which compares the stress-strain curves of alloys Ti 5 oPd 3 5.5Nbi4.5, Ti 5 oPd 3 2Fei8, Ti 44 .5Pd 3 5Nbn Fe9.5 and Ti 50 Pd 5 o, tested in compression with a deformation rate of 0.001 / s.
- the elements of a third group comprising: Cr, Mn, Cu, Zn and Ag can be introduced in a limited amount ( ⁇ 10 at%) in the TiPd and TiAu alloys instead of palladium and gold, respectively.
- 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 portion of the palladium in a TiPd alloy.
- the invention thus relates to a ductile alloy based on Ti-Pd equ 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, such that titanium always represents 50 atomic% of the final alloy.
- a ductile alloy based on Ti-Pd equ 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, such that titanium always 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.
- TiPdNb alloys do not exhibit a parasitic shape memory effect, which is advantageous.
- composition of the alloy may be formulated according to one of the following compositions, in which all the fractions are atomic:
- titanium Part of the titanium is replaced by the same atomic quantity of zirconium or hafnium, these three elements having very similar chemical properties and being easily substitutable with each other:
- M one or more of a first group consisting of: Nb, V, Mo, Ta, W, Fe, Co, Ni, Ru, Rh, Ir, Au, Pt, Cr, Mn, Cu, Zn, Ag, Al, If, Ge, Sn, Sb, In.
- a defines the offset with respect to the equi-atomic composition.
- x defines the degree of replacement of titanium by Zr and Hf. defines the fraction of substitution element.
- compositions which follow are particularly suitable:
- Composition according to the fifth composition and for which M comprises Fe and / or Nb as majority elements.
- composition according to the sixth composition and containing 50% by weight of palladium.
- Ti49.7Pd32Fe15.3Cr3 atomic composition has interesting characteristics: low memory effect, low second phase quantity, and not too high mechanical properties.
- compositions of this ninth composition containing atomically 12.5 and 10.5% of niobium exhibit a shape memory effect while the Ti5oPd35 composition.
- 5 Nbi4.5 of Figure 1 containing 14.5% niobium has no effect of this nature.
- This 14.5% niobium composition makes it possible to overcome these effects thanks to its two-phase nature.
- compositions in particular as regards titanium, of the order of 0.3% of the total, do not fundamentally change the properties of these various compositions, and do not affect their ability to replace alloys. classics.
- the invention thus relates to a cladding component for a timepiece or jewelery, made of a precious precious alloy comprising titanium.
- a cladding component for a timepiece or jewelery made of a precious precious alloy comprising titanium.
