Definitions

  • the invention relates to a rose gold alloy, particularly suitable for a timepiece, and a timepiece, jewelry or jewelry as such comprising such an alloy, such as a watch.
  • the color of gold alloys depends on their content of alloying elements.
  • AuCuAg 18ct alloys for example, a copper content greater than 180 ⁇ and a silver content of the order of 40 une gives them a red color.
  • the color evolves towards pink then towards yellow if the copper content decreases from 180 ⁇ to 150 ⁇ then from 150 ⁇ to 60 ⁇ and if the silver content increases from 40 ⁇ to 150 ⁇ .
  • watch cases or bracelets made from these usual gold alloys tended to undergo a gradual change in their color under the action of tap water, sea water, water. swimming pool water, salt water or soapy water.
  • One of the aims of the invention is to improve the resistance to a change in color of a timepiece, piece of jewelry or jewelry made from a rose gold alloy and subjected, in use, to to weakly aggressive aqueous media.
  • Another object of the invention is to define a rose-colored gold alloy, the pink of which has the most attractive aesthetic appearance possible.
  • the document JP11-335755 describes a rose gold alloy with a weight composition of 75% Au, 22% Cu, 1.5% Ag, 1% Pd, 0.5% In.
  • ingots are prepared by static casting under vacuum (melting in a graphite crucible and cooling under nitrogen). Samples are cut from the ingot in the as-cast state. The surface is prepared by polishing. A typical sample has a 20mm x 20mm x 5mm square section. All the tests are carried out on as-cast alloys, without deformation or subsequent heat treatment, and without the addition of the usual grain refiners.
  • the crystallographic analysis of the samples is carried out with an X-ray diffractometer with Cu anode.
  • a metallographic check and an analysis of the stoichiometries of the phases are carried out by SEM - EDX scanning electron microscopy.
  • the color variations are measured with a spectrocolorimeter with integrating sphere.
  • the color is defined in a conventional manner by a point in CIELAB space formed by a green-red axis on the abscissa, a blue-yellow axis on the ordinate and an axis representative of the contrast (cf. report CIE15: 2004 established by the International Commission on Illumination).
  • the measurements were all performed using the following convention: illuminant D65 and standard observer 10 ° (CIE1964).
  • the color differences ⁇ E are defined by DE2000 (equation 8.36, paragraph 8.3, report CIE15: 2004).
  • a measurement of the color difference is made between new samples (cast and polished) and samples which have undergone accelerated aging in salt spray, with exposure according to NIHS 96-50 at a temperature of 45 ° C. with a saline solution at 50g / l of pure NaCl.
  • the 750Au250Cu alloy is used as a reference base.
  • the table in figure 2 and the graph of the figure 1 synthesize the results obtained after aging in a salt spray for various massive gold alloy ingots.
  • the table in figure 3 presents other results obtained on alloys after aging for 40 days in a salt spray.
  • the 13Pd alloy is very interesting from the point of view of the color obtained and of the discoloration. This discoloration as a function of time is represented by curve 1 of the figure 1 . More generally, an alloy composed of at least 750 ⁇ of gold, copper, and with a level of Palladium (Pd) defined by: Pd ⁇ 20 ⁇ or Pd ⁇ 15 ⁇ , or 5 ⁇ ⁇ Pd ⁇ 15 ⁇ , or 8 ⁇ ⁇ Pd ⁇ 15 ⁇ , or 11 ⁇ ⁇ Pd ⁇ 15 ⁇ , is advantageous.
  • AuCuIn alloys are interesting because the results show that In makes it possible to form a single-phase alloy with Au and Cu.
  • the 5In alloy drifts little, as appears on curve 2 of the figure 1 , and already shows an improvement over the reference of a 250Cu alloy.
  • the tests carried out show that there is an optimum at the level of the color drift between 5 and 20 ⁇ In, in particular around 10 ⁇ , with a preferred interval between 7 ⁇ ⁇ In ⁇ 15 ⁇ .

  • the alloy comprises at least 1 ⁇ of Pd and 1 ⁇ of the Y element (s), or even at least 5 ⁇ of Pd and 5 ⁇ of the Y element (s).
  • Quaternary or quinternary alloys with In are also interesting. More generally, an alloy composed of at least 750 ⁇ of gold, copper, indium and at least one element Y, Y being chosen from Ca, Sr, Si, Ti, Zr, Mg or Pd is interesting , particularly when the sum of the levels of Indium and of the element Y is less than or equal to 40 ⁇ , or even 35 ⁇ , or even 30 ⁇ , or even 25 ⁇ , or even 20 ⁇ , or even 17 ⁇ , or even 15 ⁇ , or even 13 ⁇ , and / or when the sum of the rates of In and of the element (s) Y is in the range between 15 ⁇ and 40 ⁇ , or even between 20 ⁇ and 35 ⁇ , and / or when the alloy comprises at least 1 ⁇ of In and 1 ⁇ of element (s) Y, or even at least 5 ⁇ of In and 5 ⁇ of element (s) Y.

  • Such alloys include in particular the alloys comprising the components Au, Cu, Pd, In, and X, where X is at least one element chosen from Ca, Sr, Si, Ti, Zr, Mg.
  • the alloys combining both Palladium and Indium are particularly advantageous compared to the alloys comprising only one or the other of these components, as illustrated by curve 3 of the diagram. figure 1 and the results of the tables of figures 2 and 3 . It is also noted above all that the addition of a small amount of calcium and / or silicon in these alloys makes it possible to obtain an improvement in the resistance to discoloration.
  • an alloy comprising by weight at least 750 ⁇ of gold, also comprising copper, palladium and indium, the sum of the levels of palladium and indium being less than or equal to 35 ⁇ , or even less than or equal to 30 ⁇ , and / or the sum of the levels of palladium and indium being between 20 ⁇ and 35 ⁇ , is advantageous.

  • the figures 4 and 5 further illustrate the advantage of combining palladium and indium and make it possible to visualize the optimum quantities.

It appears that the best results are obtained for a palladium level of between 15 ⁇ and 30 ⁇ , or even between 19 ⁇ and 29 ⁇ , and an indium level of between 1 ⁇ and 15 ⁇ inclusive. As a note, we note that, as soon as a small amount of indium is used, for example between 1 ⁇ and 10 ⁇ , or between 1 ⁇ and 6 ⁇ , and even between 1 ⁇ and 4 ⁇ , there is a significant advantageous effect due to its combination with palladium.
  • the addition of the various components mentioned above has an effect not only on the maintenance over time of the color, but also on the color of the alloy itself.

  • the first reference alloy is a conventional 18-karat yellow gold alloy, positioned on the upper left-hand side of the diagram, near the y-axis, corresponding to a strong yellow cast.
  • the second reference alloy is a very red 18-karat gold alloy, comprising 250 cuivre of copper, positioned on the right and lower part of the diagram, near the abscissa axis.
  • the sum of the levels of palladium and indium is advantageously included in the intervals between 15 ⁇ -35 ⁇ , even between 20 ⁇ and 35 ⁇ , or even between 25 ⁇ and 33 ⁇ , which represent choices interesting for obtaining a satisfactory pink color of a gold alloy, these limits can be included or excluded.
  • rose gold alloys combining palladium and indium are interesting because they allow both to achieve a color of satisfactory aesthetics and which fades little over time.
  • the precise amounts for each of these two components and their sum represent tradeoffs between the reduction of discoloration and the aesthetics of the desired pink color.
  • the intervals for this sum of the levels of palladium and indium which make it possible both to achieve a satisfactory pink color and a weak discoloration are between 15 ⁇ and 35 ⁇ , or even between 20 ⁇ and 35 ⁇ , or even between 25 ⁇ and 33 ⁇ , as shown in previous analyzes.
  • a high level of palladium greater than or equal to 15 ⁇ , or even greater than or equal to 19 ⁇ , is favorable to the reduction of discoloration.
  • a low level of palladium less than or equal to 20% 0, or even less than or equal to 19 ⁇ or 18 ⁇ , is favorable to the aesthetics of the color pink.

  • elements such as Ir, Re or Ru make it possible to guarantee the fineness of the grain and to avoid porosities, without appreciably modify the hardness, nor affect the color, which is advantageous compared to the sought object.

  • Previous studies have underlined the interest of combining calcium or silicon with a rose gold alloy combining palladium and indium. However, this favorable effect of the Ca and Si components is also verified on any other rose gold alloy, which does not necessarily include palladium and indium. For example, we can see on the figure 2 that a 10Pd 5Ca alloy is much better than a 13Pd or 10Pd 5In alloy.
  • the addition of the Ca and Si components in rose gold alloys comprising platinum also makes it possible to obtain alloys which are better resistant to discoloration.

  • the upper limits of preferential concentration are different for Ca and Si, because it appeared that their behavior as a function of the concentration in the alloy is not identical. It is in fact preferable to avoid the formation of precipitates in order to be able to deform and / or polish the solid alloy.
  • concentration of Ca and Si should be adjusted by a person skilled in the art depending on the composition chosen for the rose gold alloy.
  • such a rose gold alloy according to the embodiments of the invention may not include silver, which induces the negative effect of yellowing the color of the alloy and even of making tender this color towards an unsightly greenish color, moving it away from the sought-after pink.
  • silver does not have a very effective effect on the durability of the color over time, compared to the other alloys studied. There are therefore two good reasons to exclude money from all the achievements proposed above. However, alloys comprising silver are not totally excluded since they could still take the advantages mentioned above.
