Definitions

  • the present invention relates to a method of manufacturing a micromechanical part made of amorphous metal.
  • the technical field of the invention is the technical field of fine mechanics. More precisely, the invention will belong to the technical field of methods of manufacturing parts made of amorphous metal.
  • micromechanical parts can be produced by micromachining or stamping or by injection into a mold.
  • an advantageous solution consists in directly casting the part in amorphous metal so as to obtain by casting the final geometry or a geometry close to the final geometry requiring only a few alterations.
  • the lack of crystal structure implies that the properties of the amorphous metal part (especially mechanical properties, hardness and polishability) do not depend on the manufacturing method. This is a major advantage over traditional polycrystalline metals for which the foundry blanks exhibit reduced properties compared to forgings.
  • a first aspect is that cooling should not be too slow because there is then a risk of partial or total crystallization and therefore of losing the properties of amorphous metals.
  • the presence of a single crystallite can be prohibitive for reasons of mechanical properties or visual appearance, given that such crystallites will inevitably appear during the finishing steps. It is therefore essential to have sufficiently rapid cooling during casting to guarantee the amorphicity of the part.
  • the molds are made of metal, for example steel or copper, allowing heat to be quickly extracted. Depending on the ability of the alloy chosen to become amorphous, it is possible with this method to obtain parts with a thickness of the order of 10mm.
  • the second aspect to consider comes from the fact that the cooling should not be too fast because there is a risk of solidification before the mold cavity is completely filled.
  • metal molds such as copper or steel
  • thermal energy is quickly dispersed, leading to a risk of premature solidification.
  • a second drawback is a shaping problem.
  • This shaping problem comes from the small size of the mold and the footprint of the micromechanical part to be manufactured.
  • the cost of these inserts and of the additional operations linked to them can become very high, making the process unusable industrially.
  • amorphous metals have the particular characteristic of softening while remaining amorphous in a given temperature range [Tg - Tx] specific to each alloy and not very high because these temperatures Tg and Tx are low. This then makes it possible to reproduce very precisely fine and precise geometries because the viscosity of the alloy decreases sharply and the latter can be easily deformed in order to match all the details of a mold.
  • the time available before the alloy eventually crystallizes is limited. If the geometry has many complexities of low thicknesses, the time required for the complete filling of the mold may be greater than the time available, resulting in partial or complete crystallization of the part and a loss of its mechanical properties in particular.
  • LIGA consists of three main stages of treatment; lithography, electroplating and casting.
  • LIGA X-Ray technique which uses X-rays produced by a synchrotron to create structures with a high aspect ratio
  • LIGA UV technique a more accessible method that uses ultraviolet light to create structures with low aspect ratios.
  • X-Ray LIGA is a microtechnology manufacturing process developed in the early 1980s.
  • an X-ray sensitive photoresist polymer typically PMMA (poly (methyl methacrylate)
  • PMMA poly (methyl methacrylate)
  • an electrically conductive substrate is exposed to parallel high-energy x-ray beams from a synchrotron radiation source through a mask partially covered with an x-ray absorbing material.
  • Chemical removal of exposed (or unexposed) areas of the photoresistive polymer enables a three-dimensional structure to be obtained which can be filled by electrodeposition of metal.
  • the resin is chemically removed to produce a metal mold insert.
  • the mold insert can be used to produce polymer or ceramic parts by injection molding.
  • the main advantage of the LIGA technique is the precision obtained by the use of X-ray lithography (DXRL). This technique allows to have microstructures having high aspect ratios and high precision to be fabricated in a variety of materials (metals, plastics and ceramics).
  • the LIGA UV technique uses an inexpensive ultraviolet light source, such as a mercury lamp, to expose a photoresistive polymer, typically SU-8. Since heating and transmission are not a problem in optical masks, a simple chrome mask can be substituted for the sophisticated X-ray mask technique. These simplifications make the LIGA UV technique a much cheaper and more accessible technique than its X-ray counterpart. However, the LIGA UV technique is not as efficient in producing precision molds and is therefore used when the cost must be kept low and when very high aspect ratios are not required.
  • the LIGA process poses a problem concerning the choice of materials. Indeed, two materials are necessary: a material for the substrate and a material that will be deposited.
  • the material for the substrate must be photo-structurable so that plaster or zircon cannot be used.
  • For the deposited material it must be able to be deposited via electroplating so that metallic materials are the only possible ones.
  • such materials generally have thermal characteristics such that they ensure good heat dissipation and therefore good cooling. This ability to properly dissipate thermal energy would cause, for an amorphous metal alloy shaped in the LIGA mold, too rapid hardening and would therefore prevent good formation of the parts.
  • the LIGA process for the manufacture of the mold is such as to limit the possible geometries since such a three-dimensional mold would require manufacturing layer by layer.
  • Patent documents are also known in the state of the art. CH707351A2 , EP2466394A1 and EP2835698A , which relate to other examples of the manufacturing process of these parts.
  • step c) consists in dissolving said mold.
  • said first material is subjected to a rise in temperature above its melting point allowing it to locally lose any crystalline structure, said rise being followed by cooling to a temperature below its temperature. glass transition allowing said first material to become at least partially amorphous.
  • the shaping step b) is simultaneous with a treatment making said first material at least partially amorphous, by subjecting it to a temperature above its melting point followed by cooling to a temperature. temperature below its glass transition temperature allowing it to become at least partially amorphous, during a casting operation.
  • This embodiment is characterized in that the critical cooling speed of the first material is less than 10K / s.
  • the shaping is done by injection.
  • the shaping is done by centrifugal casting.
  • the second material is zircon having an effusivity of 2300 J / K / m 2 / S 0.5 .
  • the second material is of the plaster type composed mainly of gypsum and / or silica, having an effusivity of between 250 and 1000 J / K / m 2 / s 0.5 .
  • the first material has a critical cooling rate less than or equal to 10K / s.
  • the invention also relates to a component made from a first material being a metallic material capable of becoming at least partially amorphous, characterized in that it is manufactured using the method according to the invention.
  • the invention further relates to a timepiece or jewelry piece comprising the component according to the invention, said component is chosen from the list comprising a middle part, a bezel, a bracelet link, a gear train, a hand, a crown, an escapement system anchor or balance, tourbillon cage, ring, cufflink or earring or pendant.
  • the figures 1 to 6 represent the different steps of the process for producing a watch or jewelery component 1 also called the first part 1 according to the present invention.
  • This first part 1 is made of a first material.
  • This first part 1 can be a covering part such as a middle part, a bezel, a bracelet link, a ring, cufflinks or earrings or a pendant or a functional part such as a gear 3, a needle. , a crown, an anchor 5 or a balance 7 of the exhaust system 9, a tourbillon cage.
  • the first material is advantageously an at least partially amorphous material. More particularly, the material is metallic, by which it is understood that it comprises at least one metallic or metalloid element in a proportion of at least 50% by mass.
  • the first material can be a homogeneous metal alloy or an at least partially or completely amorphous metal.
  • the first material is thus chosen capable of locally losing any crystalline structure during a rise in temperature above its melting point followed by sufficiently rapid cooling to a temperature below its glass transition temperature, allowing it to become at least partially amorphous.
  • the metallic element may or may not be valuable.
  • the first stage represented in the figure 2 , consists in providing a mold 10. This mold 10 has an imprint 12 which is the negative of the part 1 to be produced. This is a so-called lost wax mold.
  • This type of mold consists of a mold 10 made of a material which can be destroyed or dissolved after use to release said part.
  • the advantage of this type of mold is its ease of manufacture and release, which is independent of the geometry of the impression. It is thus possible to easily produce imprints of complex and / or hollowed out geometries, without inserts.
  • This mold can be obtained by covering a wax or resin model, itself obtained by injection, by additive manufacturing, by machining, or by sculpture.
  • This mold 10 comprises a conduit 14 so that the liquid metal can be poured into it.
  • This mold 10 is thus made of a second material.
  • the material of the mold is chosen to have specific thermal properties.
  • the goal here is to have a mold for the lost wax casting which is made of a material allowing the amorphous material of the micromechanical part not to crystallize while completely filling the mold cavity.
  • Crystallization of amorphous metals occurs when these, when in a viscous or liquid state, are not cooled quickly enough to prevent atoms from structuring among themselves.
  • this characteristic is defined by the critical cooling rate, Rc, ie the minimum cooling rate to be observed between the melting temperature and the glass transition temperature in order to maintain an amorphous state of the material. Therefore, it becomes necessary to have a mold 10 made of a material which dissipates thermal energy sufficiently well to ensure a cooling rate R greater than Rc.
  • foundry molds are made of steel or copper alloys in order to have a high R value.
  • this capacity to dissipate thermal energy should not be too great. In the event that this capacity is too great, the risk is that the first material forming the first part freezes before being able to completely fill the cavity 12 of the mold 10.
  • the present invention proposes to use the thermal effusivity criterion E in combination with Rc.
  • This effusivity makes it possible, depending on the thickness of the first part to be produced, to obtain cooling which guarantees an amorphous state of the material, that is to say R> Rc. Indeed, if the criterion of effusivity is important, the amorphicity is linked to the thickness of the part to be manufactured. It is easily understood that, for a given thickness, a high effusivity risks causing a solidification of the material before the latter has been able to fill the whole of the mold, whereas a too low effusivity risks causing crystallization. According to the invention, it will be considered that the effusivity will be chosen within a range going from 250 to 2500 J / K / m 2 / s 0.5 .
  • the effusivity of plaster-type materials is 250 - 1000 J / K / m 2 / s 0.5, while for zircon, it will be 2300 J / K / m 2 / s 0.5 .
  • the second step consists in providing the first material, that is to say the material constituting the first part 1. Once provided with the material, the rest of this second step consists in shaping it as visible to the eyes. figures 3 and 4 . For this, a casting process is used.
  • Such a process consists in taking the first material which was provided during the third step without having subjected it to a treatment making it at least partially amorphous and putting it under liquid form.
  • This liquid form is effected by melting said first material in a pouring container 20.
  • the first material is in liquid form, it is poured into the cavity 2 of the mold.
  • the first material is then cooled so as to give it an amorphous shape.
  • the cooling is carried out by dissipation of heat from the mold 10, that is to say by using only the thermal characteristics of the material constituting the mold, in other words the cooling is carried out only thanks to the effusivity of the mold and only the mold / air interface to give the amorphous or at least partially amorphous character to the metallic material of the component.
  • the cooling is therefore carried out without the use of any quenching medium other than air or a gas, for example helium.
  • the material constituting the mold 10 will be chosen to have an effusivity within a range of 250 to 2500 J / K / m 2 / s 0.5 , this thermal effusivity of a material being the capacity of the latter to exchange thermal energy with its environment.
  • this thermal effusivity of a material being the capacity of the latter to exchange thermal energy with its environment.
  • the cooling rate R is low compared to the molds traditionally used in metal.
  • the effusivity of steel is over 10,000 J / K / m 2 / s 0.5 and copper over 35,000 J / K / m 2 / s 0.5 .
  • This critical cooling rate Rc will be less than 15 K / s.
  • alloys forming the first material can be example (composition in atomic%): Pd43Cu27Ni10P20, Pt57.5Cu14.7Ni5.3P22.5, Zr52.5Ti2.5Cu15.9Ni14.6AI12.5Ag2, Zr52.5Nb2.5Cu15.9Ni14.6AI12.5Ag2, Zr56Ti2CuFe22.5Ag4.5, Zr56Nb2Cu22.5Ag4.5Fe5AI10, Zr61Cu17.5Ni10Al7.5Ti2Nb2, and Zr44Ti11Cu9.8Ni10.2Be25. It will therefore be understood that a mold used in the present invention cannot be made of a metallic material.
  • a first piece of amorphous metal having a thickness of between 0.5mm and 1.4mm, it being understood, as explained above, that details of smaller thickness are achievable if they are punctual and limited in size.
  • parts or parts of parts thicker than 1.4mm can be made without crystallization if they are considered to be point details and small dimensions.
  • An advantage of casting a metal or alloy capable of being amorphous is having a low melting point. Indeed, the melting temperatures of metals or alloys capable of having an amorphous form are generally two to three times lower than those of conventional alloys when we consider compositions of the same types. For example, the melting temperature of the alloy Zr41.2Ti13.8Cu12.5Ni10Be22.5 is 750 ° C compared to 1500-1700 ° C of crystalline alloys based on zirconium Zr and titanium Ti. This is to prevent damage to the mold.
  • Another advantage is that the solidification shrinkage for an amorphous metal is very low, less than 1% compared to the 5-7% shrinkage for a crystalline metal. This advantage makes it possible to use the principle of casting without fear of surface defects or of significant changes in dimensions which would be the consequence of said shrinkage.
  • Another advantage is that the mechanical and polishability properties of amorphous metals do not depend on the process of workmanship as long as they are amorphous.
  • the parts obtained by casting will have the same properties as the forged, machined, or hot-deformed parts, which is a major advantage over crystalline metals whose properties depend strongly on the crystalline structure, itself linked to the history of the process for obtaining the part.
  • the casting could be of the gravitational type.
  • the metal fills the mold under the effect of gravity.
  • the casting could be of the centrifugal type.
  • centrifugal casting uses the principle that the mold is driven in rapid rotation. The liquid metal poured inside sticks to the wall by centrifugal force and solidifies. This technique allows centrifugation and pressure on the material which causes degassing and expels the impurities contained in the bath of liquid metal to the external part. Smaller cavities can be filled compared to simple gravitational casting.
  • the casting could be of the injection type.
  • Such injection casting uses the principle according to which the mold is filled by means of a piston which comes to apply a very large force to push the liquid metal. This thrust then makes it possible to introduce the liquid metal into the mold in order to better fill it.
  • the casting may be of the type by counter-gravity, by pressure molding, by vacuum casting.
  • the third stage consists in separating the first part 1 from the mold 10.
  • the mold 10 in which the amorphous metal has been overmolded to form the first part 1, is destroyed by using a jet of water under high pressure, by dissolving in water or in a chemical solution, or by mechanical removal.
  • this is chosen to specifically attack the mold 10.
  • the aim of this step is to dissolve the negative 1 without dissolving the first part 5 made of amorphous metal.
  • a hydrofluoric acid solution is used to dissolve the mold. The end result is then obtaining the first piece of amorphous metal.
  • the first step consisting in providing the negative 1 can also include the fact of preparing said negative Indeed, it is possible to decorate the negative 1 so that surface finishes can be directly produced on the first part . These surface finishes can be a “Geneva coast” decoration, beaded, diamond snailed or a satin finish.
