Definitions
- the invention relates to a method of marking a metal substrate by integrating luminescent particles within the passivation layer of the metal substrate.
- optical detection of integrated luminescent particles allows the authentication and traceability of a metal substrate, particularly in the context of the fight against counterfeiting.
- the object of the present invention relates to a method for marking a substrate by means of luminescent particles, in particular submicron particles.
- the substrate thus marked is identifiable only at the wavelengths to which the particles emit or absorb. Therefore, under normal conditions of use, the marker is not visible to the naked eye and therefore does not alter the visual appearance of the substrate. This technique can thus make it possible to differentiate a counterfeit object from a non-counterfeit object.
- the luminescent marker can be detected by means of a suitable detector recognizing the luminescence signature, thus providing a method of traceability and authentication.
- the marker is only revealed under non-visible light, UV, IR, or near IR.
- the present invention relates to a method of marking a metal substrate comprising the following steps:
- the metal substrate can also be pretreated in a concentrated (NaOH, KOH, etc.), optionally oxidizing, or slightly oxidizing (carbonate, silicate) base solution.
- This pretreatment makes it possible to strip the surface to be treated in order to eliminate staining (staining, grease) as well as the natural passivation layer that is normally insufficient to ensure good anticorrosion properties.
- the metal substrate it is anodizable materials, that is to say materials of which at least the upper layer can be oxidized.
- the passivation layer designates this oxidation layer.
- the metal substrate is a material capable of forming a porous oxide layer on the surface. It may advantageously be chosen from the group comprising stainless steels; tin; zinc; titanium; aluminum and its hardening alloys (series 1000 to 8000 which may contain Si, Fe, Cu, Mn, Mg, Cr, Ni, Zn or Ti atoms) or molding (series 20000, 40000, 50000 and 70000 which may contain B, Cr, Sn, Co, Ni, Ti, Cu, Mn, Mg, Si, Zn); and their mixtures.
- the metal substrate is preferably aluminum, or aluminum-based alloy.
- the anodization (oxidation) step can be carried out under direct current, alternating current or pulsed, in particular when the substrate is made of aluminum or aluminum-based alloy.
- Electrolyte baths can create a porous oxide layer like sulfuric, chromic, sulfuric-boric phosphoric anodizing, or even autocolored anodizing or anodizing in alkaline medium.
- the thicknesses of the porous layer are variable (up to a hundred micrometers) depending on the anodizing parameters such as the electrolyte concentration, the temperature, the current density and the chemical additives.
- the oxidation step may alternatively be carried out by immersing the metal substrate in a strong acid solution, preferably an aqueous solution comprising at least one of the components selected from the group consisting of HCl, FnO 3 , H 2 SO 4 or mixtures thereof.
- a strong acid solution preferably an aqueous solution comprising at least one of the components selected from the group consisting of HCl, FnO 3 , H 2 SO 4 or mixtures thereof.
- stripping of the substrate surface is simultaneously performed.
- Clogging is the step which makes it possible to close the pores of the porous layer and thus to provide the properties of corrosion resistance.
- the inorganic luminescent particles may advantageously be chosen from the group comprising the particles based on, and advantageously constituted by, metal oxide; metallic sesquioxide; metal oxyfluoride; vanadate metal; of metal fluoride, and mixtures thereof.
- It may especially be particles selected from the group comprising Y 2 O 3 ; YVO 4 ; Gd 2 0 3 ; Gd 2 O 2 S; LaF 3 ; and their mixtures.
- the particles are advantageously doped with one or more active centers of the family of lanthanides or of the family of transition elements.
- the inorganic luminescent particles can be used in mixtures to create a luminescent optical code.
- the inorganic luminescent particles are doped with ions of the family of lanthanides, advantageously europium.
- the intensity of the luminescence depends on the doping rate and can go through a maximum.
- the doping of these particles may vary from 0.5 to 50% relative to the number of moles of metal constituting the particles, more preferably from 1 to 5%.
- markers ie several types of luminescent particles can be used to mark the substrate.
- the amount of each type of incorporated particles may be different.
- each type of particle can have its own signature.
- the authentication of the substrate may require the detection of several particles at different wavelengths.
- the particles may comprise within the same particle different optical signatures detectable at different wavelengths. It is then diptych or triptych particles for example. It is particularly advantageous to use inorganic particles in view of their greater resistance to photobleaching phenomena which degrade the luminescence of organic markers. In addition, the marking solutions used in this process have a longer life than those containing organic markers.
- the particles may have a spherical, cubic, cylindrical, parallelepipedic shape.
- the size of the particles is defined by their largest average size, that is to say by their diameter when they are spherical, their average length when they are rod-shaped.
- the luminescent particles are particles whose average size is advantageously between 4 and 1000 nanometers.
- the particles are nanoparticles.
- the average size of the nanoparticles is advantageously between 4 and 100 nanometers, more preferably between 20 and 50 nanometers.
- the particles, and more advantageously the nanoparticles can be encapsulated (coated), in particular in a polysiloxane or silicon oxide matrix.
- the new polysiloxane or silica surface can then be functionalized with organosilane coupling agents, such as substituted alkoxysilanes such as aminopropyltriethoxysilane or derivatives of the same family.
- organosilane coupling agents such as substituted alkoxysilanes such as aminopropyltriethoxysilane or derivatives of the same family.
- these surface modifications of the particles can affect the hydrophilic / hydrophobic character of the particles and thus modify the affinity and diffusivity of the inorganic luminescent particles within the passivation layer. A better homogeneity of the distribution of the luminescent particles can thus be obtained.
- the particles are coated, their average size also remains within the size ranges mentioned above. In general, the coating increases the average particle size of the order of 5 to 15 nanometers. If necessary, the submicron dimension of the nanoparticles makes it possible in particular to facilitate their incorporation into the passivation layer of the metal substrate.
- This step of incorporating the particles into the metal substrate can be advantageously carried out by dipping the substrate in a colloidal suspension of the inorganic luminescent particles.
- the metal substrate may be immersed, quenched for a period of time preferably between 5 and 120 minutes in the colloidal suspension, more preferably between 10 and 60 minutes.
- the colloidal suspension is preferably at a temperature that may be between 90 and 100 ° C., more advantageously still between 96 and 99 ° C.
- the colloidal suspension has a particle concentration of between 0.01 and 10 g / l, more preferably between 0.01 and 1 g / l.

- a water-miscible organic solvent such as for example an alcohol (glycol , propanol).
- it is a suspension in a liquid consisting of 100% water.
- the colloidal suspension may also comprise at least one additive selected from the group consisting of surfactants, dispersing agents, and mixtures thereof.
- the incorporation of the luminescent label is carried out by diffusion in the passivation layer of the metal substrate, after anodization (oxidation), while the porosity of the passivation layer is open. It is only during the clogging step that the passivation layer closes and immobilizes the particles. The marker is thus trapped in the passivation layer of the metal substrate and can not be removed without the passivation layer being destroyed.
- the stage of incorporation of the luminescent particles can be implemented in dye baths (organic or inorganic dyes) generally used in anti-corrosion treatment processes of metal substrates, such as parts aluminum for example.
- the marking implemented does not modify the manufacturing processes of the metal substrate.
- the clogging step of the passivation layer is advantageously carried out simultaneously with the step of incorporating the inorganic luminescent particles.
- the secondary clogging baths may be particle free. It may especially be a water bath at a temperature between 30 and 99 ° C. The substrate can thus be quenched for 10 to 60 minutes in the secondary clogging baths.
- the metal substrate After the clogging step, the metal substrate is dried. It can also be rinsed with water at room temperature before being dried.
- the surface of the marker, ie particles can be functionalized so as to improve the chemical affinity with the passivation layer and thus reduce the desorption of the marker during immersion in the clogging bath.
- the object of the present invention also relates to the metal substrate obtainable by the method described above.

- the nanoparticles in this example are of quasi-spherical shape and have a size of 20 nanometers in diameter for non-coated nanoparticles, and 30 nanometers for coated nanoparticles.
- the acid solution used to oxidize the metal substrate consists of a concentrated 2/1 v / v HCl / HNO 3 mixture.
- the metal substrate used is an aluminum strip 5 mm wide, 3 cm long, and 0.08 mm thick.
- An aluminum strip is immersed in the acid solution. After 10 to 30 seconds and after evolution of gas, the coverslip is rinsed with MQ water (MilliQ resistivity> 18 ⁇ ) and immersed in the nanoparticle solution for a period of between 30 minutes and 1 hour, at room temperature.
- MQ water MicroQ resistivity> 18 ⁇
- a luminescent deposit after drying is present on all the coverslip but the cover is not homogeneous.
- the concentration of nanoparticles (coated or uncoated) in the suspensions is 1 g / l in YV0 4 : Eu in water.
- An aluminum strip is immersed in the acid solution. After 10 to 30 seconds and after evolution of gas, the coverslip is rinsed with MQ water and immersed for 30 minutes in the solution of nanoparticles (YV0 4 : Eu previously coated with a layer of polysiloxane or silicon oxide) heated at 99 ° C. The coverslip is then drained and dried in air.

- Tamb Ambient temperature, 25 ° C
- np nanoparticles
- the abrasion resistance tests were carried out by friction of the metal substrate with a cloth soaked with water and / or ethanol once the coverslip has cooled. These examples show that it is necessary to treat the metal substrate by an oxidation step (acid treatment), and that it is advantageous to use nanoparticles coated with a layer of polysiloxane or silicon oxide. In addition, the clogging step is advantageously carried out at a temperature above room temperature.
- the concentration of nanoparticles (coated or uncoated) in the suspensions is 1 g / l in YV0 4 : Eu in water.
- an aluminum strip is immersed in the acid solution. After 10 to 30 seconds and after evolution of gas, the coverslip is rinsed with MQ water. It is then immersed in a first sealing solution, rinsed and if necessary, dipped in a second sealing solution.
- the nature of the clogging bath, the immersion time and the temperature of the baths are shown in Table 2.
- Luminescence and coverage are observed after air drying of the lamellae.
- example 3 30 minutes
- the slides are successively immersed in a pre-clogging bath at 50 ° C. containing the nanoparticles, then in a water bath at 99 ° C. These blades are rinsed or not between the two baths.
- This two-step sealing method is currently used in the prior art concerning the introduction of organic labels in the surface treatment of aluminum.
- the time required to effect the clogging of an aluminum substrate is generally of the order of 2 min / micrometer of oxide.
- the nanoparticle concentrations are 1 g / L and the clogging bath temperature is set at 99 ° C.
- the nanoparticles used are coated or not with a layer of polysiloxane.
- the metal substrate can be dried without rinsing or after cold rinsing.
- a clogging time of 30 minutes is sufficient but an extension of immersion does not affect the appearance of the deposit.
- the objective of this series of manipulations is to confirm the influence of particle size on the integration of markers during the clogging step.
- micrometric particles of europium doped yttrium vanadate are commercial particles (Phosphor Technology QHK 63 / FF-U1) without specific shape and having an average size of 2 micrometers.

- the particle concentrations are 1 g / l, the solvent is water and the clogging bath temperature is 99 ° C.
- one of the slides is rinsed with distilled water just after leaving the clogging bath and before drying (AR), the other is simply allowed to air dry (SR). ).
- the dispersion of micrometric particles is prepared by adding glass beads having a diameter of 4 mm in a stirred mixture of micrometric particles in water. After stirring for 24 hours, the suspension is white and the particles sediment rapidly if agitation is not maintained in the clogging flask.
- the glass beads allow the shear attrition of the micrometric particles and thus promote their suspension in the aqueous phase by deagglomeration of powder grains, without changing the size of the unit particles. On lamellae treated with micrometric particles, a slight white veil appears after drying. The marking is not "invisible" to the eye unlike the examples concerning the use of particles having an average size of less than 1000 nanometers.
- the size of the luminescent label having an average size of less than 1000 nanometers is in agreement with the porosity sizes of the passivation layer of the metal substrate. Indeed, a micrometric marker remains on the surface of the substrate and can only be partially or not trapped during the step of sealing the porosity.
