Definitions
- the present invention relates to a nickel-free and copper-free gray gold alloy having a hardness particularly suitable for watchmakers, jewelers and jewelers.
- the invention also relates to a process for preparing this alloy.
- Nickel with its allergenic potential tends to be abandoned.
- its alloys exhibit reduced hardness and deformability that lend themselves poorly to the fields of jewelery and watchmaking.
- the increase in the copper concentration is to the detriment of other elements having whitening effects.
- Japanese Patent Application Publication No. JP-A-8-003662 discloses white gold alloys of the Au-Pd-In, Au-Pd-Sn or Au-Pd-Bi types. These alloys are intended for the preparation of metal clays, that is to say of clays of precious metals.
- Metal clays are indeed generally defined as being a raw material for the manufacture of jewelery or works of art and comprising a very fine powder of precious metals, an organic binder and water. After forming, they are dried and burned so as to remove the organic binder, so that only the sintered metals remain.
- This Japanese patent application therefore relates to a white gold alloy powder of Au-Pd-In, Au-Pd-Sn or Au-Pd-Bi type to have excellent sinterability.
- a white gold alloy powder of Au-Pd-In, Au-Pd-Sn or Au-Pd-Bi type to have excellent sinterability.
- a binder plasticizer: di-n-butyl phthalate
- a surfactant ethyl-cellulose
- a gold alloy In order not to require rhodium-plating, a gold alloy must guarantee, according to ASTM Method D1925, a YI value: D1925 ⁇ 19 (YI: "yellowness index”), considered as "good white” or "premium” and included in the Grade 1 category (see also http://www.utilgold.com/goodery technology / colors / whit e guide and Proceedings of Santa Fe Symposium 2005, pp. 103- 120).
- CIE being the acronym of the International Commission on Illumination and Lab the three coordinate axes
- the colors of the gold alloys are defined in the tri-chromatic space according to the ISO 8654.
- a YI ⁇ 19 value corresponds in first approximation to [
- the object of the present invention is to provide a nickel-free and copper-free gray gold alloy having satisfactory mechanical properties as well as a high whiteness (Grade 1) while not requiring rhodium-plating.
- the gray gold alloy according to the invention may be prepared by a process in which: the components of the gray gold alloy are placed in a crucible; the crucible is heated until the components have melted; the molten alloy is cast; it is allowed to solidify; it is tempered with water; it is subjected to at least one cold rolling; and annealing under a reducing atmosphere.
- the preferred composition of the gray gold alloy according to the invention is the following (expressed in mass percentages):
- the alloy comprises at least 20% of Pd; it comprises at least 1.5% of Zr or Nb;
- the alloy according to the invention always satisfies the following conditions: -2 ⁇ a ⁇ 2 b ⁇ 10 and
- HV annealed (Vickers hardness after annealing)> 85. These properties are those that must have a gray gold alloy to meet the requirements of watchmakers, jewelers and jewelers. Preparation of the alloy according to the invention
- the alloys according to the invention are prepared under the following conditions:
- the main elements forming the alloy preferably have a purity of 99.95% with the exception of gold with 99.99% and Zr with 99.8%;
- the alloy is obtained by melting the elements in a crucible (for example ZrC> 2 ). The heating is obtained by induction in a sealed oven under partial pressure (for example argon at 800 mbar). The molten alloy is then cast in a graphite mold. After solidification, the mold is removed from the sealed oven and the ingot is demolded, cooled by quenching with water and optionally crushed;
- the annealing is carried out under a reducing atmosphere (preferably 80% N 2 -20% H 2 ) for 30 minutes at 850 ° C.
- a reducing atmosphere preferably 80% N 2 -20% H 2
- Table I groups together 18-carat white gold alloys of the state of the art that are commercially available.
- this table gives indications relating to the Vickers HV hardness index of the alloy in the cast state.
- Alloy No. 9 which is composed only of gold and palladium and is therefore free of copper, has a very low annealed HV value.
- Table II below includes gray gold alloys according to the invention which are ternary.
- Each of the ternary alloys 10 to 32 according to the invention therefore has satisfactory L, a, b and HV annealing values.
- Table III relates to quaternary and quinternal alloys according to the invention.
- the grain index is established according to ASTM E 112.
- the alloys 39 and 40 show a grain structure in columns oriented in the direction of solidification.
- the other alloys exhibit an equiaxed microstructure.
- Ruthenium has the most pronounced grain refining effect, however, there are many inclusions that can penalize polishing.
- Rhenium shows a capacity of refinement of the grain without formation of inclusions. The addition of rhenium at 20 to 60 ppm therefore gives excellent polishing ability.
