Surface engineering: functionalization of surface properties via the addition of new functions, development of industrial solutions around 3 key competencies:
- Tribology, providing high-level expertise and training, the development of specific test benches and the development of new technologies to limit wear and friction such as in surface microtexturing.
- Thin coatings & plasma sources, focusing on the development of innovative processes and coatings through the use of PVD and PECVD technologies, the development of industrial and laboratory equipment and the development of plasma sources.
- Diffusion coatings and ionic liquid media, focusing on diffusion coating technologies (sulfiding, nitriding) and innovative ionic liquid applications.

– Expertise in dealing with all types of problems in the field of tribology (friction, wear…), design of solutions for wearing parts subject to friction (guiding units, bearings, axles, ball & socket joints…).
– Surface treatments and coatings for tribological applications, hard coatings and functional coatings (electromagnetic field shielding, antibacterial treatments, barrier coats, optical uses, scenery…)
– Equipment and vacuum deposition sources (industrial, laboratory), Salt bath equipment.
– HEF R&D is currently helping the CARMAT company in the development of an artificial implantable and autonomic heart. HEF R&D’s objective is to optimize the tribologic behavior of this system to guarantee its reliability.
– HEF R&D is developing new technologies for reducing wear and friction. Micro-texturing is one of the most recent example of this – by using a micro-textured DLC coating, it is possible to reduce the friction of a valve tappet by 60% and reduce CO2 engine emissions by 2 g/km.
– The ExoMars mission is planning to send a probe to explore the surface of Mars. HEF R&D developed a coating for the seismic antenna. This antenna is coated with a metal alloy of which the thickness increases along its 30-metre length to obtain the desired gradient of electrical resistance.
