About Ireis

– 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.

Concrete examples of applications

– 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.
