Definitions
- the invention relates to the field of processes and installations for depositing a compact film of particles on the inner surface of a part having a hollow delimited by this surface. It may for example be a deposition of particles ordered on the inner surface of a tubular part.
- the solid particles preferably of spherical shape, may for example be silica particles.
- the invention has applications in various technical fields, such as the field of lighting and decorative objects, or that of surface structuring.
- the rate of shrinkage of the workpiece must be controlled very precisely so that it is constant and equivalent to the growth rate of the particle network, which itself depends on the evaporation rate of the bath. Also, this deposit technique is particularly difficult to control because of the number important parameters that must be taken into account, to hope to obtain the deposit of a quality film on the inner surface of the room.
- the invention firstly relates to a method of depositing a compact film of particles on the inner surface of a part having a hollow delimited by this inner surface, the method comprising the following steps :
- the invention is remarkable in that it offers a wide choice in the nature of the particles may be deposited on the inner surface of the part.
- the invention is not limited to the use of colloidal solutions.
- the invention is simple to implement compared to the technique of the prior art described above. This is explained by the principle adopted, which takes advantage of the surface current and slope of the protuberance to order the particles before they deposit on the inner surface.
- the presence of the flow generating the protuberance implies that the surface current of the carrier liquid pushes the particles to contact it to move radially outwards, in the direction of the contact line forming a stop for these same particles.
- the particles present thereon are also radially outwardly driven by gravity, due to the slope defined by this protuberance. Also, these two combined effects bring the energy necessary for the ordering of the particles against the line of contact.
- the principle proposed by the invention also facilitates the controlled deposition of a heterogeneous compact film. To obtain such a heterogeneous film, it suffices to vary the nature and / or the size of the particles dispensed on the surface of the carrier liquid.
- the method also comprises a step of placing, in the protuberance, an accentuation element of the slope defined by this protuberance, said slope accenting element having an outer surface of section narrowing in a direction opposite to that of said flow of carrier liquid generated in the hollow of the room.
- the accent element has an outer surface of conical or frustoconical shape.
- this slope enhancement element makes it possible to reinforce the pressure of the ordered particles against the nip, without requiring the increase of the power of the flow of carrier liquid generated in the hollow of the workpiece.
- the stability of the protuberance is advantageously improved.
- said protrusion and said accent element are coaxial, preferably centered in said recess of the workpiece.
- the step of generating the flow of carrier liquid in said hollow is carried out using a liquid spray mouth arranged in said hollow.
- the projection mouth is covered with one or more grids.
- the method also comprises, simultaneously with the step for generating the flow of carrier liquid in said hollow, a step of suction of said carrier liquid, a suction mouth preferably being arranged in said hollow.
- this suction mouth may be located outside the hollow.
- the projection mouth and the suction mouth can communicate respectively with the outlet and the inlet of a pump. They can therefore be part of the same hydraulic circuit.
- the step of transferring the compact film is implemented by moving said piece.
- this transfer step of the compact film is implemented by lowering the surface of the carrier liquid in the remaining fixed part.
- a solution combining the two above is also possible, without departing from the scope of the invention.
- other elements of the installation such as the spray / suction mouths can be moved simultaneously with the liquid level.
- the step of dispensing the particles is carried out using one or more nozzles, possibly mobile.
- the goal is to obtain a relatively uniform dispensation all around the protuberance. Consequently, an annular nozzle centered on the protuberance can also be envisaged, without departing from the scope of the invention.
- the nozzle could feed a dispenser providing uniform dispensing of particles all around the protuberance.
- the method applies to a tubular part.
- the cross-section of the inner surface of the part may be of any shape, symmetrical or asymmetrical, for example circular, square, or else incorporating concave and / or convex portions, or else present sharp, straight or obtuse angles.
- the inner section can be scalable in size and / or shape.
- the recess may extend along a straight line to form a tubular piece, or may extend over a non-straight line, for example curved, broken, etc.
- the hollow of the part to be coated can be opening or through, without departing from the scope of the invention.
- said particles of the compact film have a large dimension of the order of 1 nm to 500 ⁇ .
- the compact particle film is deposited on the inner surface of the workpiece is homogeneous or heterogeneous. In the latter case, particles of different sizes and / or different compositions make up the film.
- the group of steps a) to d) is repeated for the deposition of several superposed, identical or different films. It is then a multilayer coating deposited on the inner surface delimiting the hollow.
- the method preferably also includes a step of depositing a compact film of particles on the outer surface of the workpiece, simultaneously, before or after deposition of the compact film on the inner surface of the workpiece.
- all the deposition techniques deemed appropriate are conceivable, in particular those ensuring the prior formation of a compact film of particles on the surface of a carrier liquid, before the transfer of this film on a substrate.
- the invention also relates to an installation for implementing the method as described above, comprising:
- FIG. 1 shows an installation for implementing a method of depositing a compact film of particles, according to a preferred embodiment of the present invention
- FIGS. 2 to 5 represent various steps of a deposition method implemented using the installation shown in the previous figure, according to a preferred embodiment
- FIG. 6 shows a view similar to that of Figure 5, according to an alternative embodiment
- FIG. 7 represents a view of the installation shown in the preceding figures, on which several dimensions have been referenced.
- FIG. 1 there is shown an installation 1 for the deposition of a compact film of particles on the inner surface of a workpiece 2.
- the installation comprises a receptacle 3 receiving a carrier liquid 6. It is preferably a deionized water, on which the particles can float.
- the part 2 and the container 3 can be confused.
- the installation also comprises means for generating a flow of carrier liquid in the hollow 8 of the part 2 defined by its inner surface 10.
- the means here comprise a pump 12 connected to a pipe 14 at the end of which is a liquid projection mouth 16, oriented toward the surface 18 of the carrier liquid 6. More specifically, the mouth 16 placed in the liquid 6 is oriented so as to create a flow orthogonal to the liquid surface, this flow being therefore vertical.
- the projection mouth 16 is centered in the recess 8 of the part, which is here a tubular piece whose inner surface 10 has a circular section. Also, the axis 16a of the mouth 16 coincides with the axis 10a of the inner surface 10 of the part 2 partially immersed in the carrier liquid 6 of the container 3.
- a contact line 20 is defined at the interface between the inner surface 10 of the part and the surface 18 of the carrier liquid 6.
- the pump 12 is connected to its inlet to a pipe 22 at the end of which is a liquid suction mouth 24.
- This mouth can be placed in the recess 8 as shown in Figure 1, or externally to piece 2, still in the container.
- the liquid 6 sucked by the mouth 24 passes through the pump 12 before being ejected into the hollow 8 through the mouth 16.
- the suction mouth is actually placed preferentially outside this hollow 8 in which the flow of liquid must be generated, for the formation of a protuberance on the surface.
- the aforesaid protuberance is provided to form a slope on which the particles to be deposited can move by gravity and following the radially outwardly directed surface current lines.
- the installation 1 further comprises an accentuating element of the slope defined by this protuberance.
- This element is here a pin 28 having a conical outer surface 30 of section narrowing towards the bottom of the container.
- the section of the conical surface 30 narrows in a direction opposite to that of propagation of the flow of carrier liquid to be generated in the recess 8, at the outlet of the mouth 16.
- the pin 28 is arranged coaxially with the projection mouth 16. Its axis 28a is coincident with the axes 16a and 10a, and also coincides with the axis of the protuberance intended to be formed on the surface 18 of the carrier liquid.
- the pin 28 penetrates coaxially therein so as to accentuate the slope of this protrusion on which the particles are intended to float. By this accentuation, the effect of displacement of these particles towards the contact line 20 is reinforced.
- the conical surface 30 makes it possible to derive the surface current lines in a symmetrical manner, making it possible to obtain a uniform pressure at the periphery.
- the pin 28 can penetrate into the protuberance of the carrier liquid beyond its conical surface 30. It is made of a hydrophobic material to prevent the deposition of the particles on its conical surface 30. The material retained is for example Teflon (PTFE) .
- PTFE Teflon
- the installation 1 further comprises means 34 for dispensing particles 4 to the surface 18 of the carrier liquid 6.
- the size of the particles 4 can be between a few nanometers and several hundred micrometers.
- the solid particles, preferably of spherical shape, may for example be silica particles.
- Other particles of interest can be made of metal or metal oxide such as platinum, TiO 2, polymer such as polystyrene or PMMA, carbon, etc. It can also be chemical molecules.
- Other examples are glass fibers, PTFE particles, epoxy particles, Janus type particles, or so-called core-shell particles.
- the particles are silica spheres of about 1 ⁇ in diameter, stored in solution in the dispensing device 34.
- the proportion of the medium is about 7 g of particles per 200 ml solution, here butanol.
- the particles shown in the figures adopt a diameter greater than their actual diameter.
- the dispensing device 34 has one or more controllable injection nozzles 36 of about 500 ⁇ in diameter. Indeed, only a nozzle 36 has been shown in FIG. 1, but it is preferable for a substantially uniform dispensation of particles around the axis 10a, in the direction of the surface 18. To do this, it can therefore be provided several times. nozzles 36 distributed around the axis 10a, or one or more movable nozzles in a circular path centered on the same axis Finally, the installation comprises means 40 making it possible to effect a relative displacement between the workpiece 2 and the surface 18 of the carrier liquid 6. In this embodiment, the means 40 make it possible to move the workpiece 2 vertically, along its axis 10a. , with the container 3 and its equipment remaining fixed. Conventional mechanical means with motor can be used to realize these means 40.
- a method of depositing a compact film of particles 4 on the inner surface 10 of the part 2 will now be described with reference to FIGS. 1 to 5.
- the part 2 is partially immersed in the carrier liquid 6, so as to define the line of contact 20 between the two surfaces 10, 18.
- the pump 12 is actuated so as to generate the flow of the carrier liquid 44 in the recess 8, at the outlet of the projection mouth 16.
- This flow 44 oriented vertically in an ascending manner, causes a protuberance 50 on the liquid surface 18. It thus extends upwards and is centered on the axes 10a, 16a, 28a.
- the protuberance 50 generally takes the form of a dome, the center of which is traversed by the pin 28 which accentuates the slope of this dome relative to the adjacent horizontal portion of the surface 18 of the carrier liquid.
- the protrusion 50 is separated from this horizontal adjacent portion by a demarcation line 58 located more or less close to the inner surface 10 and centered in the recess 8.
- the projection mouth 16 is covered with one or more grids (not shown). It may be stainless steel grids, for example square mesh with a pitch of 1 mm.
- the dispensed particles 4 accumulate against the inner surface 10 at the contact line 20 forming a stop, all along thereof.
- the upstream front 60 of these particles has a tendency to shift radially inwards towards the axes 10a, 16a, 28a.
- the injection of particles 4 is continued even after this upstream front has exceeded the line 58 demarcation of the protuberance 50, so that it rises on the slope defined by it and that the particles partially surround the same protrusion.
- the upstream front 60 of particles rises on the slope of the protuberance 50 so that it is at a given vertical distance from the demarcation line 58, as shown in FIGS. 4.
- the upstream front 60 can then be obtained near the line of contact between the outer surface of the pin 28 and the liquid 6.
- the solid particles 4 are ordered to the surface 18 of the carrier liquid, between the demarcation line 58 and the upstream front 60 arranged around the protuberance 50, for example near its top.
- the scheduling is carried out automatically, without assistance, thanks in particular to their kinetic energy and capillary forces used at the moment of impact on the front 60.
- the scheduling is such that the compact film obtained has a structure called " hexagonal compact ", wherein each particle 4 is surrounded and contacted by six other particles 4 in contact with each other. It is then indifferently spoken of compact film of particles, or film of ordered particles.
- the compact film of particles is transferred onto the inner surface 10 of the part 2.
- This step is performed by moving the piece 2, namely by gradually removing the carrier liquid, in the vertical direction.
- This step is shown diagrammatically in FIG. 5. It is effected by means 40 acting directly on the part 2 to move it, while simultaneously the dispensing of the particles 4 is continued on the upstream front 60. This causes a transfer of the film on the inner surface 10 defining the hollow of the room.
- the particle injection and the removal rate of the part 2 are adjusted so that the particle front 60 remains in a substantially identical position, shown in FIGS. 3 and 4.
- the flow rate of particles can be of the order of 0.1 ml / min to several tens of milliliters per minute, while the linear speed of the part 2, also called pulling speed, can be of the order of a few mm / min at several hundred mm / min.
- the part 2 remains fixed and the level of the surface 18 of the carrier liquid 6 is lowered.
- This is for example achieved using the means 40 by lowering the container and all its equipment, in particular the mouths 16, 24.
- a movable plate 62 can be secured to the mouths 16, 24 and slide along the inner surface 10 of the workpiece in the manner of a piston head.
- Figure 7 shows several preferred ratings for the implementation of the invention.
- the inside diameter D1 of the surface 10 of the part 2 can be of the order of 8 mm to several tens of centimeters.
- the diameter D2 of the demarcation line 58 of the protuberance 50 is, for example, of the order of 25 mm, whereas the vertical distance "d" between the projection mouth 16 and the demarcation line 58 is for example of the order of 15 mm, but can be between a few millimeters and several tens of centimeters.
- the height h of the protrusion 50, in configuration without the slope accenting pin, is for example of the order of 3 to 4 mm.
- the diameter D2 of the demarcation line 58 of the protuberance 50 is between 30% and 50% of the diameter D1 of the inner surface 10.
- the diameter D3 of the mouth 16 is for example between 8 mm and several tens of centimeters.
- the maximum diameter of the conical pin 28 is of the order of a few millimeters to several centimeters, depending on the diameter D1 of the inner surface 10 of the part. More generally, the line of contact between the carrier liquid 6 and the conical surface 30 has a diameter of between 30% and 50% of the diameter D2 of the demarcation line 58 defining the protrusion 50.
- the angle of the conical surface 30 relative to the axis 28a of the pin 28 is for example of the order of 45 °. Other values are nevertheless possible, for example from 20 ° to 170 °.
- the particles 4 used may be homogeneous or heterogeneous.
- the nature and / or the size of the particles 4 dispensed may vary during the deposition of the same layer, depending on the needs encountered.
- the deposit may be interrupted along the inner surface 10 and then taken up again.
- the deposition of the compact film of particles is then preferably carried out so as to create an iridescent effect. It may for example be to coat the inner surface of a bulb to give it this iridescent effect. To do this, microspheres of silicas may be used, for example with a diameter of about 1 ⁇ . By changing to a diameter of approximately 0.3 ⁇ , an opalescent effect is created.
- the invention can also be applied to the field of structuring interior surfaces.
- the inner surface of heat transfer fluid heat exchanger tubes, being structured increases the exchange surface with the fluid passing through this tube.
- the particles deposited on the inner surface of the tube make it possible to act as focusing lenses for subsequently etching the substrate by laser.
- the particles may be quartz, polystyrene or silica.
- the inner surface of parts In the field of mechanics, it is also possible to structure the inner surface of parts to improve their coefficient of friction.
- the structuring is then performed by plasma etching through a particle mask, preferably spherical silica particles. This principle can for example be applied in piston liners.
- reverse opal type structuring can be applied to certain sensors of particular chemical species.
- the reverse opal structuring is carried out inside tubes where a liquid circulates.
- the periodic porosity of the inverse opal is then functionalized to capture on the surface the desired chemical species, likely to be contained in the liquid.
- the capture of this species in the porosity of the periodic opal inverse structure consequently modifies the optical response of the opal (diffraction). This response is then detected and analyzed, so as to conclude whether or not the desired species is present.
