THERMI-LYON, a true technological showcase

Historically the group's first site, THERMI-LYON was created in 1960 to meet the needs of the Rhône-Alpine mechanical engineering industry.

Its high level of investment in human resources and technology has enabled it to extend its reach nationwide and internationally.

THERMI-LYON has played a major role in the development and industrialization of new heat treatment processes, and has won several MIDEST and A3TS innovation awards.

New processes have been deployed to improve the wear and galling resistance of stainless steels without compromising corrosion resistance: THERMI-SP®.

This powerful multi-treatment unit meets a wide range of customer requirements.

All equipment is linked by a supervision network, enabling continuous data acquisition and remote interrogation.

THERMI-LYON has invested heavily in the development and mastery of DLC coating using PACVD technology.

An adapted environment (clean room) has made it possible to create a dedicated workshop for coating tribological layers.

Recently, THERMI-LYON developed a new range of DLC deposits based on PVD technology. This new development makes it possible to produce dehydrogenated carbon-based coatings for specific applications, depending on the working environment.

Since its creation, THERMI-LYON has adapted to different contexts and set up an organization to meet the requirements of the automotive, aerospace and medical markets, as well as the special machinery sector.

Mechanical components of an electric car

Electric cars have profoundly transformed the automotive industry by rethinking traditional mechanical principles. Unlike internal combustion vehicles, which rely on a combustion engine, these vehicles run on an electric motor powered by a battery. This change has led to a major evolution in the design of mechanical components, which must be adapted to the new [...]

What does alloy ageing involve?

Alloy ageing is a widespread phenomenon in the metallurgical industry. Whether used in the aeronautics, automotive or other high-tech sectors, metal alloys evolve over time under the effect of various factors such as temperature, mechanical stress and the environment in which they are exposed. This transformation can be beneficial to the [...]

Focus on press hardening and its advantages

Press-hardening serves a very specific purpose: to prevent part deformation during the rapid cooling phase induced by quenching. This method improves the performance of steels by giving them a martensitic structure, without the need for reworking. Designed for large production runs of parts with complex geometries, [...]

Focus on martensitic hardening and its advantages

The aim of martensitic hardening is to bring out a specific constituent in steels, called martensite, to make them harder and more resistant to wear and mechanical stress. It is one of the oldest known heat treatments of metals, and is still used today, thanks to its effectiveness and the [...].
