THERMI-NITROX®: 1 treatment for 3 properties
Nitrocarburizing + post-oxidation
THERMI®-NITROX is a thermochemical treatment in the nitrocarbon family with oxidation and impregnation finishes.
This THERMI®-NITROX process has a major advantage in that it offers multifunctional properties. The result is increased resistance to wear, seizure and corrosion.
From a technical and economic point of view, it can advantageously replace a carbonitriding-type heat treatment followed by a surface treatment: 1 treatment instead of 2.
It can also be used to replace certain surface treatments (e.g. hard chrome).
Ce traitement est réalisé à basse température <600°C et sur pièces finies .
For study and order
Information to be communicated :
- Drawing of the part (possibly including: area to be protected).
- Number of parts per shipment per year.
- Nature of the steel: AFNOR (or commercial) designation - Specification of the layers to be produced (with machining allowance, if any).
- Previous treatments (pretreated, tempered, stabilized, annealed).
business sectors concerned
As the THERMI-NITROX® process is multifunctional, we can apply it in a very wide range of sectors.

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.
