PLATIN MEDI ZrN®
SPECIFIC COATING FOR MEDICAL APPLICATIONS
PLATiN® MEDI ZrN is a zirconium nitride coating. This composition has the particularity of limiting bonding and adhesion phenomena encountered when working with non-ferrous metals. It has good abrasion resistance, good corrosion resistance and excellent bonding and adhesion resistance.
These properties make it an excellent candidate when titanium nitride and chromium nitride reach their limits. Its excellent resistance to deformation also enables it to be used on light or lightly loaded alloys.
It can also be perfectly combined with a prior nitriding operation - Duplex treatment, which considerably increases the service life of medical devices.
PLATiN® MEDI ZrN coating is deposited by PVD (Physical Vapor Deposition) using a magnetically guided arc evaporation process.

The Thermilyon group's sites certified for the medical markets are THERMI-PLATIN and THERMI-BUGEY.
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.
Vacuum deposits are classified into several categories: anti-wear, friction, decorative and biocompatibility. The applications are therefore very varied: automotive components, aerospace, tooling, cutting tools, medical devices, decorative parts...
Vacuum deposits are of the order of a few microns, and are applied to finished parts. As a result, every precaution must be taken to anticipate deformation. Dimensional tolerance must take into account the extra thickness created by the deposit itself (a few microns).
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.
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.
