Abstract
Description
L'invention concerne la réalisation sur un objet d'un décor présentant des parties apparentes en deux matériaux différents.The invention relates to the production on an object of a decoration having visible parts in two different materials.
On a déjà proposé dans la technique des procédés permettant de réaliser des décors bicolores sur des objets métalliques. De tels décors sont généralement obtenus en procédant à un premier placage de l'objet à l'aide d'un premier métal donné, puis à un second placage avec un métal différent, et en mettant ensuite à découvert, par endroits, le premier métal, par usinage ou par une attaque chimique. Outre le fait qu'elle n'est applicable facilement qu'à des objets présentant des faces planes, cette méthode nécessite un repérage extrêmement précis de la profondeur de l'usinage, de manière que celui-ci soit suffisamment profond pour traverser la première couche de placage sans toutefois perforer la seconde.Methods have already been proposed in the art making it possible to produce two-color decorations on metallic objects. Such decorations are generally obtained by carrying out a first plating of the object using a first given metal, then a second plating with a different metal, and then exposing, in places, the first metal , by machining or by chemical attack. In addition to the fact that it is easily applicable only to objects having flat faces, this method requires an extremely precise location of the machining depth, so that it is deep enough to pass through the first layer. plating without, however, perforating the second
On sait également réaliser des décors bicolores sur des objets en utilisant la technique des masques. Selon ce procédé, on recouvre d'abord la totalité de l'objet d'un premier métal, on dispose ensuite en certaines des parties de cet objet un masque qui y adhère et on dépose alors un second métal sur les parties de l'objet non masquées. Une telle technique nécessite toutefois un positionnement rigoureux du masque, ce qui, spécialement dans le cas de petits objets, est difficile à réaliser.We also know how to make two-color decorations on objects using the mask technique. According to this process, the entire object is first covered with a first metal, a mask is then attached to some of the parts of this object, and a second metal is then deposited on the parts of the object. not masked. Such a technique however requires rigorous positioning of the mask, which, especially in the case of small objects, is difficult to perform.
Cette technique est en outre difficilement utilisable, dans lécas, par exemple, où l'on désire entourer l'une des faces d'un objet, en un matériau déterminé, d'un mince filet d'un matériau différent d'une largeur donnée. En effet, le masque ayant une dimension déterminée, toute variation dimensionnelle de l'objet influera sur la largeur du filet obtenu.This technique is also difficult to use, in cases, for example, where one wishes to surround one of the faces of an object, in a determined material, with a thin thread of a different material of a given width. . Indeed, the mask having a determined dimension, any dimensional variation of the object will influence the width of the net obtained.
Dans le cas où le filet est réalisé dans une saignée bordant par exemple une face de l'objet, celle-ci et la face de la saignée qui lui est adjacente sont revêtues de deux matériaux de nature différente. Il en résulte que le moindre défaut dans le positionnement et dans l'application du masque se traduit par un revêtement irrégulier au niveau de l'arête de séparation de ces deux surfaces.In the case where the net is produced in a groove bordering for example one face of the object, this and the face of the groove which is adjacent to it are coated with two materials of different nature. As a result, the slightest defect in the positioning and in the application of the mask results in an irregular coating at the level of the separation edge of these two surfaces.
On a enfin proposé (CH-A-554 756 et GB-A-2017010) de réaliser sur un objet un décor présentant des parties apparentes en au moins deux matériaux différents (étain et or par exemple). Selon ce procédé, on applique sur un support en un premier matériau un masque d'une géométrie déterminé, on creuse ensuite par des moyens chimiques ou non chimiques (p.l. par sablage, électroérosion ou insculpation au moyen d'un poinçon) les parties de ce support non protégées par le masque et l'on remplit enfin les dépressions ainsi réalisées à l'aide d'un second matériau.Finally, it has been proposed (CH-A-554 756 and GB-A-2017010) to make a decoration on an object having visible parts in at least two different materials (tin and gold for example). According to this process, a mask of a determined geometry is applied to a support made of a first material, then the parts of this support not protected by the mask and finally fill the depressions thus produced using a second material.
Dans ce procédé, toutefois, la géométrie du décor est définie dès l'origine par celle du masque. En outre, les parties du support non protégées par le masque sont attaquées chimiquement, ce qui ne permet pas de conférer au décor un contour parfaitement net.In this process, however, the geometry of the decoration is defined from the outset by that of the mask. In addition, the parts of the support not protected by the mask are chemically attacked, which does not allow the decoration to be given a perfectly clear outline.
La présente invention vise à remédier à ces inconvénients en proposant un procédé permettant la réalisation d'objets dans lesquels deux surfaces adjacentes, recouvertes de matériaux de nature différente, présentent une ligne de séparation entre les deux surfaces particulièrement nette.The present invention aims to remedy these drawbacks by proposing a method allowing the production of objects in which two adjacent surfaces, covered with materials of different nature, have a particularly clear line of separation between the two surfaces.
L'invention vise également à proposer un procédé de ce type qui soit facile à mettre en oeuvre à l'échelle industrielle.The invention also aims to propose a method of this type which is easy to implement on an industrial scale.
A cet effet, la présente invention concerne un procédé pour la réalisation sur un objet d'un décor présentant des parties apparentes en au moins deux matériaux différents, ce procédé étant caractérisé en ce qu'il comporte au moins un cycle comprenant au moins les phases successives suivantes :
- on applique sur une partie au moins du matériau de base constitutif de la surface externe dudit objet une matière de protection ou épargne;
- a protective or saving material is applied to at least part of the basic material constituting the external surface of said object;
sur une partie de la surface protégée par ladite épargne, on usine mécaniquement à l'aide d'un outil de coupe à la fois ladite épargne et le matériau de base sous-jacent ;on a part of the surface protected by said savings, mechanically using a cutting tool both said savings and the underlying base material;
on revêt la partie usinée dudit matériau de base sous-jacent d'un matériau différent.the machined part of said underlying base material is coated with a different material.
Dans une forme de mise en oeuvre particulièrement intéressante de l'invention, l'épargne est appliquée sur la totalité de la surface de l'objet. Il est ainsi possible de simplifier la production industrielle de tels décors en incluant lesdites ébauches ainsi recouvertes d'une épargne (ou « épargnées •) dans une chaîne d'usinage déjà existante, conjointement avec d'autres produits.In a particularly advantageous form of implementation of the invention, the savings are applied to the entire surface of the object. It is thus possible to simplify the industrial production of such decorations by including said blanks thus covered with savings (or "saved") in an already existing machining chain, together with other products.
Dans une autre forme de mise en oeuvre avantageuse de l'invention, les opérations mentionnées ci-dessus sont suivies d'une phase d'élimination de l'épargne, pour dégager le matériau de base constitutif de l'objet. Cette forme de réalisation est particulièrement intéressante lorsque ledit matériau de base est un matériau précieux.In another advantageous form of implementation of the invention, the operations mentioned above are followed by a phase of elimination of the savings, in order to release the basic material constituting the object. This embodiment is particularly advantageous when said base material is a precious material.
Cependant, lorsque ce n'est pas le cas, il est également possible de faire précéder les opérations mentionnées ci-dessus d'une phase de transformation superficielle de la nature du matériau de base, par exemple par attaque chimique ou par dépôt d'un matériau différent.However, when this is not the case, it is also possible to precede the operations mentioned above with a surface transformation phase of the nature of the base material, for example by chemical attack or by deposition of a different material.
Dans la présente description et dans les revendications qui suivent, le terme d'épargne désigne tout masque déposé sur tout ou partie de l'objet et destiné à préserver les parties non usinées au cours de la phase d'usinage de toute transformation pouvant survenir au cours de la phase de revêtement.In the present description and in the claims which follow, the term savings designates any mask deposited on all or part of the object and intended to preserve the non-machined parts during the machining phase of any transformation that may occur during during the coating phase.
On notera que cette épargne peut avoir une géométrie différente de celle du décor et que sa surface, qui doit être usinée pour recevoir ensuite un matériau différent du matériau de base, est nécessairement supérieure à celle occupée par le matériau rapporté.Note that this savings may have a different geometry from that of the decor and that its surface, which must be machined to then receive a material different from the base material, is necessarily greater than that occupied by the added material.
La matière constituant l'épargne sera choisie pour son caractère neutre vis-à-vis des produits utilisés au cours de la phase de revêtement. Ainsi, si celle-ci consiste en un placage électrolytique d'un métal, l'épargne sera réalisée en une matière isolante, afin de ne pas fixer elle-même ledit métal.The material constituting the savings will be chosen for its neutral nature vis-à-vis the products used during the coating phase. Thus, if it consists of an electrolytic plating of a metal, the savings will be made of an insulating material, so as not to fix said metal itself.
De même, si le revêtement est obtenu par dépôt d'un matériau sur le matériau de base, par exemple par immersion dans un métal en fusion ou par projection de celui-ci sur la partie usinée, le matériau constituant l'épargne devra posséder un caractère de non-mouillabilité par rapport audit métal, de manière à ce qu'il ne puisse se déposer sur lui.Likewise, if the coating is obtained by depositing a material on the base material, for example by immersion in a molten metal or by projection of this onto the machined part, the material constituting the savings must have a character of non-wettability with respect to said metal, so that it cannot be deposited on it.
Dans le présent texte, le mot revêtement s'entendra de toute modification superficielle de la nature du matériau. Ainsi, le revêtement peut résulter d'une transformation chimique de la surface du métal, par exemple par oxydation anodique. L'épargne, dans ce cas, sera choisie pour ses propriétés non réactives dans le cadre d'une telle oxydation.In the present text, the word coating means any surface modification of the nature of the material. Thus, the coating can result from a chemical transformation of the surface of the metal, for example by anodic oxidation. The savings, in this case, will be chosen for its non-reactive properties in the context of such oxidation.
Le matériau constituant l'épargne sera également choisi, de façon générale, pour ses qualités de bonne usinabilité, afin que la ligne de séparation entre les matériaux de natures différentes soit bien nette.The material constituting the savings will also be chosen, in general, for its qualities of good machinability, so that the line of separation between the materials of different natures is very clear.
Dans le cas où l'on désire réaliser la phase d'usinage suivant l'invention de façon industrielle, il est nécessaire que l'ébauche de l'objet soit enrobée par l'épargne de façon régulière, et avec une épaisseur connue et contrôlable, afin de pouvoir la positionner de façon précise par rapport à l'outil d'usinage. C'est pourquoi on distinguera tout particulièrement les procédés d'application de l'épargne faisant appel à des lignes de champs électriques tels que, par exemple, les. procédés d'électrophorèse.In the case where it is desired to carry out the machining phase according to the invention in an industrial manner, it is necessary for the blank of the object to be coated with the savings regularly, and with a known and controllable thickness , in order to be able to position it precisely in relation to the machining tool. This is why a particular distinction will be made between the methods of applying savings using lines of electric fields such as, for example,. electrophoresis processes.
On sait, en effet, que ces procédés fournissent des dépôts particulièrement réguliers, même lorsque les objets traités possèdent des formes compliquées. De plus, l'épaisseur de l'épargne est facilement réglable par un simple contrôle du courant et du temps de l'opération. Enfin, les épargnes appliquées par ces procédés sont électriquement isolantes et peuvent ainsi être utilisées avec une phase de revêtement faisant appel à des procédés d'électrolyse.It is known, in fact, that these processes provide particularly regular deposits, even when the objects treated have complicated shapes. In addition, the thickness of the savings is easily adjustable by a simple control of the current and the operation time. Finally, the savings applied by these methods are electrically insulating and can thus be used with a coating phase using electrolysis methods.
L'usinage de l'épargne s'effectuera mécaniquement, car seule une telle opération, à la différence des procédés de gravure chimique ou électrochimique, permet d'obtenir un contour extrêmement net et de réaliser des parties en creux de grande profondeur. Par usinage mécanique, on peut en outre obtenir des flancs de forme absolument quelconque, ce qui permet, par exemple, de réaliser des guillochis.The machining of the savings will be done mechanically, because only such an operation, unlike the chemical or electrochemical etching processes, makes it possible to obtain an extremely clear outline and to produce hollow parts of great depth. By mechanical machining, it is also possible to obtain flanks of absolutely any shape, which makes it possible, for example, to produce guillochis.
Le présent procédé a notamment été appliqué à la réalisation de briquets dont les faces principales, argentées, sont entourées d'une fine bordure « dorée •, réalisée légèrement en creux par rapport à ces faces.The present process has notably been applied to the production of lighters whose main faces, silvery, are surrounded by a fine “golden” border, produced slightly in hollow relative to these faces.
Pour ce faire, après polissage, une ébauche d'un corps de briquet a été revêtue d'argent par passage dans un bain d'électrolyse de type classique, puis a été recouverte sur toute sa surface d'une épargne d'une épaisseur d'environ dix microns par passage dans un bain d'électrophorèse commercialisé sous la dénomination de « Primaire électrocationique noir type 700-980 » CORONA. Les faces principales de l'ébauche ainsi masquées par l'épargne ont alors été usinées afin de former les filets, puis ceux-ci ont été dorés par immersion du briquet dans un bain d'électrolyse approprié de type connu.To do this, after polishing, a blank of a lighter body was coated with silver by passage through an electrolysis bath of conventional type, then was covered over its entire surface with a savings of a thickness d 'about ten microns per passage through an electrophoresis bath marketed under the name of "black electrocationic primer type 700-980" CORONA. The main faces of the blank thus masked by the savings were then machined in order to form the threads, then these were gilded by immersion of the lighter in an appropriate electrolysis bath of known type.
On constate que, dans les briquets ainsi réalisés, la ligne de séparation entre la bordure dorée et la face argentée est extrêmement nette, beaucoup plus qu'avec les procédés de la technique antérieure, ce qui confère au briquet un aspect esthétique particulièrement attrayant.It can be seen that, in the lighters thus produced, the line of separation between the gold border and the silver face is extremely clear, much more than with the methods of the prior art, which gives the lighter a particularly attractive aesthetic appearance.
Le procédé selon l'invention apporte donc un progrès technique considérable par rapport à la technique antérieure.The method according to the invention therefore provides considerable technical progress compared to the prior art.
Suivant la destination de l'objet décoré conformément à l'invention, il est possible de conserver ou non l'épargne, obtenue, par exemple, par électrophorèse. En effet, celle-ci, lorsqu'elle est transparente, confère un aspect brillant à la surface de l'objet, tout en la protégeant contre les phénomènes d'oxydation.Depending on the destination of the object decorated in accordance with the invention, it is possible to keep or not the savings, obtained, for example, by electrophoresis. Indeed, when it is transparent, it gives a shiny appearance to the surface of the object, while protecting it against oxidation phenomena.
Lorsqu'elle est opaque, elle peut elle-même faire partie intégrante du décor de l'objet.When it is opaque, it can itself be an integral part of the decoration of the object.
Lorsque l'on applique le procédé conforme à l'invention à des objets présentant des faces planes, on peut utiliser des épargnes se présentant sous la forme d'une pâte que l'on applique au rouleau, puis que l'on fait sécher avant de passer à la phase d'usinage.When applying the process according to the invention to objects having flat faces, savings can be used in the form of a paste which is applied with a roller and then dried before to go to the machining phase.
On peut également appliquer l'épargne sur le matériau de base constitutif de l'objet par projection au pistolet, par trempage dans une solution de la matière constitutive de l'épargne, ou par tout autre moyen connu dans la technique.The savings can also be applied to the basic material constituting the object by spraying with a gun, by dipping in a solution of the material constituting the savings, or by any other means known in the art.
L'épargne peut éventuellement être éliminée à la fin du procédé, par exemple par dissolution.The savings can possibly be eliminated at the end of the process, for example by dissolution.
On notera que le procédé conforme à l'invention peut s'appliquer à des objets en toute matière, même électriquement isolante, par exemple en matière plastique, que l'on soumettra alors à une phase préliminaire de métallisation, par exemple de métallisation sous vide.It will be noted that the method according to the invention can be applied to objects of any material, even electrically insulating, for example plastic, which will then be subjected to a preliminary metallization phase, for example vacuum metallization. .
Suivant le type de décor désiré, il est bien entendu possible de repéter le cycle précédemment décrit, autant de fois que nécessaire. Ce cycle peut naturellement comprendre des phases additionnelles, soit avant ou après les trois phases caractéristiques du procédé selon l'invention, soit encore entre deux quelconques de ces trois phases.Depending on the type of decoration desired, it is of course possible to repeat the previously described cycle, as many times as necessary. This cycle can naturally include additional phases, either before or after the three characteristic phases of the process according to the invention, or even between any two of these three phases.
