THERMI®-DLC DLC coating
Cette famille de revêtements DLC (Diamond Like Carbon), dédiée aux applications tribologiques, permet non seulement d’améliorer le frottement mais aussi de réduire de manière significative les usures et le grippage. Ces revêtements, intégrant le carbone amorphe hydrogéné a-C : H, représentent une solution technologique avancée dans le domaine des matériaux à couche mince (< 5 µm) et d’une dureté élevée (1500 – 2500 HV).
Thanks to their low coefficient of friction, they reduce friction losses and improve motor and mechanical efficiency, delivering outstanding performance in demanding sectors such as aerospace, plastic injection molding and power generation.
These Magslide DLC and NitroSlide DLC coatings also provide dry lubrication, eliminating the need for liquid lubrication in applications where their use is prohibited, such as the food, textile and medical sectors. The unique combination of wear resistance, high hardness and superior tribological quality significantly extends the service life of mechanical wear parts, whatever the type of part treated.
What's more, DLC coating is biocompatible, making it a preferred choice for coating medical devices, offering excellent protection against corrosion and abrasion in corrosive environments such as those encountered in medicine and thefood industry.

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.
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.
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...
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.
Incorporate carbon below the surface of the steel part to improve fatigue and wear resistance on the surface, while maintaining good core mechanical properties.
