Definitions
- the invention relates to a self-lubricating composite solid coating, in particular for an application to clockwork mechanisms.
- liquid lubricants oil lubricants
- pastes fats
- These lubricants are used sparingly on well-defined areas and in suitable quantities.
- This type of lubricant must be able to slip between two parts to minimize friction or must be removed during assembly.
- the ability to slip between two rooms can also escape from the space where it has been deposited. It is also very sensitive to the environmental conditions of temperature and relative humidity because its viscosity evolves according to these.
- lubricants are constituted by a liquid or viscous support which may contain particles having tribological properties such as carbon.
- WO2012 / 128714 describes for example a liquid containing graphene. Graphene was isolated by André Geim in 2004. It is a two-dimensional carbon crystal whose stacking leads to graphite. It appears to have interesting tribological properties.
- dry coatings which reduce friction are known. These coatings are integral with the part to be protected and present less risk of loss or chemical degradation. In addition, these coatings are less sensitive to environmental conditions. For example, coatings based on carbon nanotubes dispersed in a nickel matrix are known. Such coatings are for example described in US-A-2008 1323475.
- the coating metal is gold but this coating is derived from a bath which contains a percentage of Cadmium well above the percentage allowed by the European directives which is problematic.
- Graphite is also used as an anti-wear agent in electro-deposited composite coatings.
- the subject of the invention is a metal composite solid coating having self-lubricating properties, characterized in that it comprises particles of graphene and / or graphene oxide distributed in a metal matrix.
- FIG. 1 Schematic section of the substrate coated with the graphene metal composite.
- FIG 2 Variation of the relative amplitude of a clockwork mechanism with a coating according to the invention (a) and without coating (b) with respect to a clockwork mechanism lubricated with oil.
- FIG. 3 cut of a coated support with an extra layer of gold.
- This coating 2 comprises particles 3 of graphene and / or graphene oxide distributed in a metal matrix 4.
- particles 3 of graphene or graphene oxide are used which are in the form of fibers or flakes (aggregates of fibers or particles).
- the thickness of this coating is generally between 0.2 micron and 20 microns but preferably it is between 0.5 micron and 2 microns.
- a layer of hook 5 is for example formed of nickel or chrome gold or gold.
- the deposition of the coating is done by electroplating if the part to be coated is conductive. If it is a non-conductive part, a purely chemical deposit will be carried out for example by a process called "electroless" using an oxidizing agent (the metal cation or cations), a reducing agent and a catalyst.
- a bath containing metal ions and particles of graphene and / or graphene oxide is used, in which the object to be coated is immersed, the latter forming the cathode in a conventional electrochemical deposition assembly. in a bath.
- this bath may contain other types of particles 6 such as particles of alumina, boron nitride, tungsten carbide, diamond, bisulphide. molybdenum, PTFE and / or silicon in pure form, encapsulated carbide, nitride or oxide, or even oil droplets (eg fluorinated oil), including a mixture thereof.
- the metal ions may optionally be bonded to complexing agents well known electrochemical processes such as cyanide in the case of a bath of gold.
- the pH of the bath can be adapted with buffers at a fixed value depending on the bath chemistry, for example with boric acid in a bath of nickel buffered at acidic pH.
- the bath may also contain additives well known in electrochemical processes such as, for example, leveling agents, brighteners and voltage reducers.
- the latter may also contain surfactants which bind to the above-mentioned particles, surround them and prevent their agglomeration in solution.
- the bath will be subjected to mechanical agitation and / or ultrasonic type in order to distribute the various components as well as possible.
- the composite coating is formed according to the same principles: addition of particles 3 and 6 in the bath with surfactant and co-deposition of particles 3 and 6 with metal 4 on the object to be coated, with mechanical and / or ultrasonic agitation of the bath.
- the deposited metal may be pure metal such as pure nickel or a metal alloy such as nickel with phosphorus or an alloy of copper, tin and zinc (bronze).
- the choice of the metallic material depends on the desired side result. For example, phosphorus nickel will make it possible to obtain a coating having non-magnetic properties and bronze will make it possible to obtain a decorative coating.
- Graphene or graphene oxide can also be deposited with gold and / or copper ions for coating with a base matrix of gold or gold-copper. Other metal ions for producing this base matrix can still be used, for example noble metal ions such as palladium or platinum ions.
- graphene or graphene oxide particles can co-deposit with nickel and phosphorus in a bath containing nickel (II) ions and phosphorous acid.
- nickel (II) ions and phosphorous acid Another example would be the co-deposition of graphene or graphene oxide in the presence of gold and copper ions. It should be noted that if graphene oxide is used in the bath, it can be co-reduced during the electrochemical deposition process and can be converted into reduced graphene oxide.
- a deposit of gold with a thickness of 5 to 100 nm can be done by a galvanic process or other methods (vapor phase deposition or sputtering) over the coating deposited by electrochemistry or electroless deposit and after polishing (see FIG 3).
- This thin layer of gold is subjected to frictional forces which cause a superficial penetration of gold into the metal matrix containing graphene and / or graphene oxide.
- Such a solid coating is not possible with pure graphene especially because of the cost of the material and a too small thickness.
- the chosen solution combines the effects of graphene with metal and other components. It is possible to choose a coating having the property of greatly reducing friction by increasing the level of graphene or obtaining a hard surface which therefore limits wear by adding to graphene hard particles selected from the group comprising alumina, diamond, boron nitride, tungsten carbide, including a mixture of these.
- the interest is therefore to combine in a metal matrix of a particular metal or alloy particles or aggregates of graphene incidentally combined with other inorganic or organic particles to meet each specific need. It is not a matter of a chemical combination but of the presence of various particles distributed in the metal matrix.
- the coating is integral with the timepiece which is a guarantee of longevity and better resistance to environmental conditions
- the deposition of the coating can be limited to the zones that are subjected to friction, the rest of the part being able to be masked during the deposition.
- composite coatings comprising a nickel metal matrix in which graphene or graphene oxide agglomerates are dispersed.
- the coatings are produced from a bath comprising from 150 to 600 g / l of nickel sulphate, from 4 g / l to 40 g / l of nickel chloride, from 30 g / l to 50 g / l of boric acid and from 0.5 g / l to 5 g / l of graphene oxide in powder form.
- the pH of the bath is between 3 and 4 and the bath temperature maintained between 50 and 70 ° C.
- the coatings are deposited directly on watch parts by applying a current density of 1 to 20 A / dm2.
- Another example is that of coatings obtained from a bath comprising from 60 to 150 g / l of nickel in the form of nickel sulphate, from 5 g / l to 30 g / l of phosphorous acid, from 30 g / l to 50 g. / L of boric acid and 0.1 g / L to 5 g / L of graphene oxide in powder form.
- a pH of between 1 and 2 composite coatings based on nickel phosphorus and graphene oxide can be obtained by applying a current density between 0.5 and 10 A / dm2 and more particularly between 1 and 5 A / dm2. Coatings thus formed lead to performances such as those described in FIG. 2 (curve (a)) at thicknesses between 0.5 and 5 microns.
- Curve (a) corresponds to the ratio in percentage between the amplitude of oscillation amplitude of the balance of a standard movement with an escape wheel provided with a coating according to the invention divided by the amplitude value of oscillation of the rocker of the same type of movement provided with an exhaust (teeth of the escape wheel and pallets of anchor) lubricated according to the prior art.
- Curve (b) corresponds to the percentage ratio between the oscillation amplitude value of a rocker with an escape wheel and uncoated and unlubricated anchor pallets divided by the oscillation amplitude value exhaust (teeth of the escape wheel and pallets anchor) lubricated according to the prior art.
