Definitions
- the invention relates to the coating of metal surfaces. More specifically, it relates to treatments for coating the surface of a metallic material intended to give it a three-dimensional visual effect.
- a visual effect can be obtained with holograms, which are obtained by recording and reproducing an image using two laser beams on a photosensitive support capable of recording light interference of good contrast.
- supports are, for example, thermoplastic films, photopolymers, photosensitive films ...
- the decoration of metallic packaging in steel or aluminum is a privileged use of this technique, which has the disadvantage, for the metallurgical enterprise, of requiring the intervention of an external supplier who delivers the photosensitive support to it.
- the support is liable to become detached from the packaging or to be damaged during the treatments and manipulations undergone by said packaging after bonding or co-laminating.
- the object of the invention is to propose a method making it possible to obtain three-dimensional visual effects on the surface of a metallic material without having recourse to the application to this surface of a photosensitive support.
- the subject of the invention is a method of coating the surface of a metallic material having a crystallographic structure, according to which a first coating of said material is carried out with a layer of a metal or of a metallic alloy with melting point equal to T f , of thickness less than or equal to 2.5 ⁇ m, characterized in that:
- a heat treatment is carried out on said first coating by a rapid heating means so as to bring the surface of said first coating to a temperature between 0.8T f and T f ;
- a second coating is deposited from a metal or a metal alloy, of thickness less than or equal to 1 ⁇ m.
- said first and second coatings have melting points less than or equal to 700 ° C.
- Said first and second coatings can be made of the same material.
- the deposition on said second coating is then carried out of a transparent mineral film.
- Said metallic material to be coated may preferably be carbon steel, stainless steel, or aluminum or one of its alloys.
- Said first coating can preferably be produced by electrodeposition or by a vacuum deposition process.
- Said rapid heating means may preferably be an infrared heating device, an induction heating device, a plasma effluvium device with a non-reactive gas or an ion bombardment with a non-reactive gas .
- Said second coating can preferably be produced by electrodeposition or by a vacuum deposition process.
- Said transparent mineral film can be deposited by a reactive plasma deposition process.
- Said first and second coatings can each consist of tin and / or aluminum.
- Said mineral film can consist of a metal oxide or a mixture of metal oxides, preferably chosen from oxides of austenitic stainless steel, chromium, titanium, silicon, zinc, tin.
- the metallic material can be in the form of a moving strip, and the various stages of the process can be carried out continuously by means of installations arranged successively on the path of the moving strip.
- the invention also relates to a device for coating a metallic material in the form of a strip, characterized in that it comprises means for scrolling said strip and, successively arranged on the path of said strip:
- the device may comprise, following said second means for coating said strip with a layer of a metal or a metal alloy, means for coating said strip with a transparent mineral film.
- the invention also relates to a metallic material, characterized in that it comprises on at least one of its surfaces a metallic coating with a three-dimensional visual effect, said coating being formed directly on said surface of the material, and produced in particular by the previous process.
- the invention consists in obtaining the three-dimensional visual effect sought by a series of surface treatments of the metallic material itself.
- a multilayer coating is thus obtained which cannot be detached from the metallic material and can be produced by the metallurgical company which manufactured the basic material.
- This coating in addition to its aesthetic qualities, has many technical advantages, and allows the manufacturer of the metallic material to retain complete control of the decoration process.
- FIGS. 1 to 6 show the aspects of different coatings obtained by various variants of the method according to the invention.
- the starting material is a metallic material, such as carbon steel, stainless steel, aluminum or an alloy thereof, etc. It is for example in the form of a plate or a wound strip. In the latter case, it is possible to carry out the treatment which will be described by unwinding the strip and scrolling it continuously in an installation where the apparatuses making it possible to carry out the different stages of the treatment are arranged one after the other. on the path of the strip. In order for the desired aesthetic effect to be obtained, the metallic material used as a substrate must have a crystallographic structure.
- the first process step is the deposition of a first coating, comprising a metallic member (aluminum or tin, for example) or a metal alloy, preferably low-melting point T f of the order of 700 ° C or lower.
- This coating must have a thickness less than or equal to 2.5 ⁇ m.
- it is produced by an electrodeposition process, or by a vacuum deposition process.
- vacuum deposition methods which can be used, mention may be made of the conventionally known methods of vacuum evaporation, magnetron sputtering, ion plating, self-induced ion plating.
- the second stage of the process is a heat treatment carried out on the first coating, by a rapid heating means, such as infrared lamps, an inductor, a plasma effluvium, or an ion bombardment with a non-reactive gas such as 'a rare gas.
- a rapid heating means such as infrared lamps, an inductor, a plasma effluvium, or an ion bombardment with a non-reactive gas such as 'a rare gas.
- This heat treatment must bring the surface of the first coating to a temperature between 0.8 T f and T f .
- T f be less than or equal to 700 ° C.
- the third step of the process is the deposition of a second coating, from a metallic element or an alloy identical or not to the material of the first coating.
- This coating must have a thickness not exceeding 1 ⁇ m. It can be produced by the same methods as the first coating.
- the method may include a fourth step consisting in depositing on the second metallic coating a transparent mineral film.
- a transparent mineral film Materials such as oxides of austenitic stainless steel, chromium, titanium, silicon, zinc, tin (non-limiting list) and their mixtures are particularly indicated.
- This transparent mineral deposition can be carried out by any means known for this purpose, the methods using a reactive plasma deposition being particularly indicated. If this film has a thickness less than or equal to 1 ⁇ m, a colored coating can be obtained by interference effect of the mineral film. Green, yellow, blue, purple and red colors are accessible in this way, depending on the refractive index of the deposited material. In general, this transparent film gives an appearance of additional depth to the three-dimensional appearance patterns obtained following the first three steps of the process.
- the size of the patterns obtained depends on the amount of energy used during the second step of the process and on the thickness of the coating: the patterns will be all the greater as this amount of energy and / or this thickness will be important.
- the use, as coating material during the first step of the process, of a metal or alloy with a low melting point (700 ° C. or less) makes it possible to carry out the metallurgical transformation of the coating during the second step in a time very brief.
- the heating methods which have been mentioned make it possible to provide the necessary energy in a minimum of time.
- the method according to the invention has several advantages. As we said, it allows the manufacturer of metal products to retain full control of the process.
- the coating generating the three-dimensional visual effect here being an integral part of the support, there is no risk of it coming off during subsequent treatments and manipulations.
- the coating thus obtained improves the resistance of the substrate to cosmetic corrosion.
- the coating is also more resistant to ultraviolet and temperature. It is less sensitive to fingerprints. It has great surface hardness, which makes it less susceptible to scratches. It is easy to clean and is resistant to cleaning products and other mechanical stresses.
