Definitions
- the present invention relates to a method of depositing on a substrate, a layer of a wear-resistant decorative coating, this substrate constituting at least part of a decorative and / or utility object. .
- the surfaces of decorative objects have a golden color.
- these objects are not solid gold, but made of a non-noble metal such as brass, stainless steel, zinc, etc.
- this golden appearance can be obtained by applying a surface coating of gold or gold alloy, most often by a galvanic process. If this coating is to be resistant to wear and corrosion, its thickness must at least reach 10 micrometers.
- a base layer consisting of a precious metal alloy at 1 ⁇ or 18 carats is generally galvanically deposited.
- the corrosion resistance of these alloys is often insufficient, and their color does not correspond exactly to the colors of solid alloys, such as those defined for example by the standards of the Swiss watch industry NIHS 03-50 (alloy 1N1, 2N18 , 3, Hti, 5N).
- the corrosion resistance of gold plating, as well as their color, can be improved by galvanic application of a surface layer of gold alloy having a purity greater than or equal to 22 carats, and corresponding exactly to the desired color. .
- titanium nitride coatings are commonly applied, deposited by reactions chemical in the gas phase, by reactive evaporation, by ionic spraying or by cathode sputtering, on decorative objects made of metal, carbides or sintered metal nitrides, or ceramic. These coatings have the advantage of being very resistant to wear and having a golden appearance.
- the American patent No. 3857 682 proposes to deposit under vacuum a thin layer of gold over the titanium ni ⁇ tride. This idea was taken up in US Patent No. 252,862 and Swiss Patent No. 631,040, applied to the decorative field, with the aim of giving the surface of titanium nitride the exact color of gold, or d 'a gold alloy. During the use of a part thus coated, the wear of the gold coating only occurs on sharp corners and reveals the coating of titanium nitride, the color of which differs little from that of the rest. of the coating.
- Japanese publication No. 58.153-776 and European publication No. 38.29 1 describe a process for the conjugate deposition of titanium nitride and gold, intended to form over all or part of the thickness of the coating a titanium nitride / gold compound.
- this procedure seems to pose corrosion problems, and the color obtained is also far from the standard colors of gold coatings.
- the successive deposition of thin layers of titanium nitride and gold, by vacuum process also improves the gloss of the coating.
- the gold deposition or gold alloy processes not allowing the color to be varied final coating from one treatment to another.
- the present invention proposes to overcome these various drawbacks and in particular makes it possible to considerably improve the wear resistance, the adhesion and the appearance of a deposit based on titanium nitride with a final coating of gold.
- At least one first layer of at least one metal chosen from the group is deposited under vacuum on the surface of the substrate.
- FIG. 1 represents a schematic view illustrating the different phases of the method according to the invention
- Figure 2 illustrates the principle of color measurement according to the standard of the International Commission on Lighting CIE 1976
- FIG. 3 is a graphic representation illustrating the brightness of the colored surface of a coating of titanium nitride as a function of the quantity of nitrogen which it contains,
- FIG. -I illustrates the rate of green and red colors reflected by a coating of titanium nitride as a function of the quantity of nitrogen which it contains,
- FIG. 5 represents the rate of blue and yellow colors reflected by a coating of titanium nitride as a function of the quantity of nitrogen which it contains.
- the method described consists in depositing under vacuum, for example by sputtering, by vacuum evaporation or by ion spraying, titanium in the presence of nitrogen on the surface of a metallic or non-metallic object. 10 schematically represented by FIG. 1.
- the amount of nitrogen introduced into the treatment enclosure varies continuously from zero to a value defined by the desired result, so that the composition of the coating 11 starting from the gross surface of the The object gradually varies from pure titanium to a titanium nitride having an approximately stoichiometric composition.
- the electrical polarization of the treated object is varied simultaneously, in order to gradually vary the mechanical compression stresses from a minimum value at the start of the coating to a maximum value at the end of the coating.
- a coating is obtained which, starting from the gross surface of the object, presents a determined gradient of nitrogen concentration, resistance and mechanical stress.
- the coating obtained has minimal shear stresses on the contact surface of the object and the coating, as well as the desired optical, mechanical and anticorrosive surface properties.
- the method After depositing the first layer of titanium nitride, the method consists in preparing the upper surface of this layer in order to make it suitable for receiving, thereafter a layer of gold or of gold alloy, deposited by galvanic process , having the desired final color, as close as possible to a standard color defined by the standards in use.
- an activation of the titanium nitride surface is carried out during a first step of the second treatment phase by intense ion bombardment. After this first treatment step, gold atoms are deposited, forming an intermediate layer 12, during a second step of this second treatment phase.
- This deposition of gold atoms is carried out under vacuum by evaporation, by ion projection or by sputtering, while continuing to carry out ion bombardment of the titanium nitride surface. During this second step, the power of this ion bombardment is gradually reduced.
- the activated titanium nitride surface is ready to receive a layer 13 of pure gold or of a gold alloy of high purity, deposited by a galvanic process, making it possible to give it the desired color.
- This color can be modified at will by changing the composition of the galvanic bath or by modifying the parameters defining the conditions of the galvanic deposition process.
- different objects of the same batch previously coated with a base layer of titanium nitride, then with a thin layer of gold, by a vacuum process can be coated with a final layer having shades of different colors depending on whether they have been treated in a particular galvanic bath or according to whether the treatment conditions have been modified.
- This deposition can be carried out in the presence of one of the following elements: Carbon, Nitrogen, Oxygen, Boron, Silicon, Fluorine, Chlorine, Sulfur and Phospore.
- the level of these elements is gradually increased during the vacuum deposition phase of the metal or metals mentioned above.
- the objects to be treated are increasingly negatively polarized. This makes it possible to obtain a coating having an increasing concentration of non-metallic elements and having states of increasing mechanical stresses.
- a thin metallic layer is deposited, partly simultaneously, which may be made of gold or of a gold alloy, but also of one or more precious metals such as for example Platinum, Palladium, Rhodium, Silver, Irridium, Osmium, Rhenium and Ruthenium.
- This second layer preferably has a thickness of between 100 and 10 * 000 ⁇ .
- This galvani ⁇ deposit is generally gold or a high-carat gold alloy, for example a gold alloy of at least 22 carats comprising, as an alloying element, Indium, Nickel, Cobalt, Cadmium, Copper, Silver, Palladium, Zinc or Antimony.
- this deposit can also consist of one or more precious metals such as Platinum, Palladium, Rhodium, Silver, Irri- dium, Osmium, Rhenium or Ruthenium, an alloy of one of these metals with one or more other metals, or possibly a non-precious metal or alloy.
- the method makes it possible to treat the surface of an object so as to coat it with an adherent hard and corrosion-resistant layer having approximately the desired color, then to effect on this base layer a final coating having exactly the color desired and adhering perfectly to this base coat.
- a stainless steel watch case previously degreased and dried, is placed in a vacuum cathode spray enclosure. During a first stage, it undergoes an ion bombardment with argon ions, so as to remove the last superficial traces of contaminant. The object is then negatively polarized at a few tens of volts, and we begin to deposit titanium by sputtering. As the thickness of the coating increases, the electric polarization of this object is gradually increased, and an increasing flux is introduced into the enclosure. nitrogen, so as to deposit a titanium nitride compound which is increasingly rich in nitrogen.
- the next step is to bombard the titanium nitride layer with argon ions. As the power of this bombardment is reduced, a thin layer of gold is deposited by sputtering, with an increasing flow of gold atoms, until that this layer reaches a thickness of 0.1 micrometer. The watch case is then removed from the enclosure. It is given its final surface color by electrolytically applying a coating of 0.3 micrometers of 2a carat gold alloy, containing traces of indium and nickel, the color of which corresponds to the standard 2 N 18.
- a thin layer of rhodium having good wear resistance on the outer surface of a brass ball-point pen tube.
- the object is introduced into the cathodic spraying enclosure where it undergoes the same treatment as in the previous example.
- the nitrogen is replaced by a hydrocarbon, such as for example methane, so as to deposit a titanium carbide with an increasing proportion of carbon.
- a thin layer of silver is deposited by sputtering.
- a last layer of rhodium is then galvanically deposited on top of the silver until this layer reaches a thickness of 0.3 microns.
- FIG. 2 illustrates the principle of measuring the color of the light reflected by the surface of an object according to the CIE 1976 standard of the. International Commission of Lighting. Three quantities are measured and correspond to three axes defining an orthogonal reference in three dimensions.
- the L axis defines the brightness, the -a, + a axis corresponds to the two complementary colors respectively green and red.
- the axis -b, + b corresponds to the two complementary colors respectively blue and yellow.
- FIG. 3 represents a comparative graph between the brightness of titanium nitride and of various standard gold alloys.
- the brightness is represented in arbitrary units and on the abscissa the rate of nitrogen entering into the composition of titanium nitride, according to an arbitrary unit.
- the shine of the surface of a coating of titanium nitride is represented by a curve 20.
- the brilliance of different gold alloys is represented by a succession of dots. It can be seen that the gloss of all the standard alloys represented is greater than all of the titanium nitride compounds.
- the figure * ⁇ represents the quantity of green and red light reflected on the one hand by a coating of titanium nitride and on the other hand by various standard gold alloys. As before, the nitrogen content of the titanium nitride compound is plotted on the abscissa in an arbitrary unit. Curve 21 represents the amount of green and red light reflected by the coating of titanium nitride.
- FIG. 5 represents the quantity of blue and yellow light respectively reflected by a coating of titanium nitride and by various coatings of standard gold alloys.
- the nitrogen content in the titanium nitride has been plotted on the abscissa in an arbitrary unit.
- Curve 22 represents the amount of blue and yellow light reflected by the titanium nitride coating as a function of its composition.
- the blue and yellow light reflected by the different alloys is represented by a succession of dots.
