DLC treatment: High-performance tribological coating
DEEPslide dlc PVD coating
Cette nouvelle technologie de revêtement DLC (Diamond Like Carbon) par PVD (Physical Vapor Deposition) est conçue pour les applications tribologiques nécessitant une protection exceptionnelle contre l’usure et une friction réduite.
Le carbone de type diamant permet d’améliorer le frottement mais aussi de réduire de manière significative les usures et le grippage. Ce revêtement, intègre une couche carbone amorphe déshydrogéné CrC + a-C et représente une solution technologique avancée dans le domaine des matériaux à couche mince (< 5 µm) et d’une dureté élevée (1500 – 2500 HV).
Grâce à leur faible coefficient de frottement, ils permettent de limiter les pertes en frottement et d’améliorer les rendements moteur et mécanique, offrant ainsi une performance exceptionnelle dans des secteurs exigeants comme l’aérospatiale, la fabrication de moules pour l’injection plastique et la production d’énergie.
Ces revêtements assurent également une lubrification sèche, éliminant le besoin de lubrification liquide dans les applications où leur usage est proscrit, notamment dans les secteurs alimentaire, textile et médical. La combinaison unique de résistance à l’usure, de haute dureté, et de qualité tribologique supérieure prolonge significativement la durée de vie des pièces d’usure en mécanique, quel que soit le type de pièce traité.
Cette solution offre une alternative au a-C:H. Le DLC a-c conserve les propriétés de frottement et de protection contre l’usure élevées avec une couche sans hydrogène.
Conclusion of DLC treatment :
In short, DLC (Diamond Like Carbon) treatment is a state-of-the-art tribological solution. This solution offers protection against wear, corrosion and seizure. Thanks to its low friction and non-stick properties, this coating is ideal for applications requiring enhanced durability and performance, notably in the aerospace, automotive, plastic injection and power generation sectors.
In addition to extending the life of mechanical components, DLC treatment helps reduce maintenance and lubrication requirements, while complying with strict environmental standards. Adaptable to a wide range of materials and configurations, it represents an essential technological advance for industries seeking efficiency and durability.

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.
