Bronze and eggplant coatings
Deep colors for your projects
Our PVD coatings combine several elements to produce a variety of browns approaching bronze , and deep purples such as eggplant.
The part's surface finish contrasts the final shade and adds depth, sparkle or shine, depending on your project requirements.
These coatings are particularly well-suited to the watchmaking, jewelry, fittings, writing accessories and tableware markets.
In addition to their decorative qualities, our PVD coatings have functional properties:
- Wear and scratch resistance thanks to hardness exceeding 3000 HV (Vickers hardness)
- Corrosion resistance
For study and order
To help us study your project, please provide us with the following information:
- Plan of the part (including areas not to be coated).
- Material of the part to be coated.
- Expected color and finish
- Number of parts per shipment and year.

Our FAQs
Vacuum deposition is a surface treatment used to deposit a material or alloy on a mechanical part.
The use of vacuum technology ensures a perfectly clean, non-polluting process.
It is not subject to REACH legislation.
The deposition method depends above all on the nature of the coating to be deposited and the substrate.
If the substrate cannot be heated to high temperature, the deposition must be carried out using low-temperature technology.
If the coating to be deposited consists of a solid element (metal or graphite target), a physical process such as PVD is used. If the coating consists of a gas or liquid, a chemical process such as CVD or PACVD is used.
This process greatly increases resistance to wear, abrasion, friction and corrosion. As a result, component life is greatly extended.
Standard thicknesses are of the order of 3µm and deposition is carried out on finished parts.
PVD is physical vapor deposition. The element to be deposited is obtained by evaporation or sputtering via a physical process. PACVD is plasma-assisted chemical vapor deposition. The element to be deposited is obtained from chemical reactions. Plasma enables this chemical reaction to take place at lower temperatures.
Nature of steel or carbide, if steel treated, please specify the treatments carried out. Desired characteristics (hardness), quantities of parts per shipment and per year, drawings of the part and specifications. If possible, how the part will be used and its final purpose.
