PLATIN MEDI BETA®: specific coating for medical applications
A biocompatible coating for the medical sector
Titanium nitride was the first coating to be developed on an industrial scale, and is still the most widely used coating today. Thanks to an interesting combination of properties and its attractive color (gold), this coating has rapidly established itself in many fields: conventional machining, material shaping by stamping and injection molding, biomedical, decorative...
Thanks to its multi-layer structure, PLATiN® MEDI Beta offers superior performance to standard TiN coatings.
PLATiN® MEDI Beta is deposited by PVD (Physical Vapor Deposition) using the magnetically guided arc evaporation process. This industrial process can be used to coat steels and titanium at temperatures up to 450°C, as well as stainless steels at low temperatures (200°C).

Our FAQs
The Thermi-Lyon group sites certified for the medical markets are THERMI-LYON and THERMI-PLATIN. The THERMI-BUGEY site is in the process of being certified.
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.
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.
