- the purpose of the invention is therefore to propose a deposition process which makes it possible to obtain a colored surface coating based on intermetallic alloys which have noble metal contents of greater than 50% or 75% by weight and which, in addition, are available via plasma techniques.
- a metal chosen from the group consisting of gold, platinum, palladium, ruthenium, rhodium, silver, aluminum and titanium,
- a metal alloy comprising at least said metal, or
- a composite comprising said metal, said method consisting in: a) depositing on at least a part of said object (1), simultaneously the species (A) and (B):
- the species (A) being chosen from the group constituted by said metal, said metal alloy comprising said metal and said composite comprising the said, and the species (B) being chosen from the group consisting of one or more rare earth oxide (s), at least one rare earth nitride (s) and with one or more rare earth oxynitrile (s), to form a homogeneous thin layer (2) consisting of a homogeneous metal matrix.
- the object (1) to be coated may be, for example, a luxury object such as a spectacle frame, a lighter, a jewel, a watch or one of these components ...
- the invention relates to a method of depositing a colored surface coating on at least a part of an object (1) comprising at least one physical deposition step:
- a metal chosen from the group consisting of gold, platinum, palladium, ruthenium, rhodium, silver, aluminum and titanium, a metal alloy comprising at least said metal, or

- magnetron technique magnetron technique
- the oxide and / or the rare earth oxide mixture is deposited at a content ⁇ 25% by weight, and preferably between 10 and 25% by weight, relative to the weight of said metal or metal alloy.
- Coatings with a noble metal content Two categories of colored coatings will be distinguished according to the noble metal content. Coatings with a noble metal content:
- the thickness of the homogeneous composite thin film (2) is generally between 0.5 micrometers and 20 micrometers. Indeed, the thickness of these different coatings (or “coatings") is closely related to the deposition technique used. In general, the average thicknesses of these "coatings" are 5 ⁇ m. However, in some cases, a thickness of 20 microns is possible.
- Example 1 Depositing a Colored Coating Based on Gold and Erbium by DC Sputtering
- a mixture of gases, argon and oxygen, can be used to set the working pressure.
- the working pressure varies between 3 E-3 mbar and 5 E-2 mbar but preferably 9 E-3 mbar.
- the gas system for sputtering has more oxidizing characteristics than the working environment with a single gas such as argon.
- Table I shows some working conditions that have resulted in different surface coatings: Table I
- the surface coatings obtained are homogeneous and have thicknesses ranging from 0.1 to 10 micrometers.
- the gold content of the various coatings was determined using a model 438VP scanning electron microscope marketed by the company of Cari Zeiss and equipped with an energy dispersive X-ray spectrometer (supplied by Noran System). .
- Example 2 Deposits of a Colored Coating Based on Gold and Praseodymium or Neodymium by DC Sputtering

- a praseodymium or 99.999% pure 3N metal neodymium target of 24mm diameter (ESPI Materials ASHLAND USA) is installed in the second magnetron cathode of the system.
- the reactor is closed and the pumping is started.
- the reactor is purged, at least once, by introducing a few cm3 of argon 5.0, as soon as the vacuum value of 8 E-5 mbar.
- argon is introduced to set the working pressure. This working pressure varies between 3 E-3 mbar and 5 E-2 mbar but preferably 1.5 E-2 mbar.
- the surface coatings are homogeneous and have thicknesses ranging from 0.1 to 10 micrometers.
- the gold content of the various coatings was determined using a Cari Zeiss Model 438VP scanning electron microscope equipped with an energy dispersive X-ray spectrometer from Noran System.

- a surface of a Grade 4 titanium object is cleaned with a simple cotton cloth soaked in 96% pure ethanol available from the Sigma-Fluka supplier (product code 02890).
- the surface of the Titanium grade 4 object on which will be deposited the colored coating based on gold and Praseodymium or Neodymium can be indifferently polished, sanded in a controlled manner or not.
- the object to be treated is introduced into the Leybold brand reactor equipped with a radio frequency RF spraying system at 13.56 MHz with 2 cathodes 25 mm in diameter. The cathodes are arranged in a confocal manner.
