Treating a surface consists in modifying the surface part without touching the base material. Thus, an object or a part having undergone a surface treatment will have for example a visual aspect different from the one it had before or chemical, mechanical, electrical, optical, magnetic, tribological surface properties different from the base material from which it is issued.

Vacuum deposition consists of depositing a thin layer of another material (metal, ceramic, etc.) on a metal or non-metal object.


PVD stands for "Physical Vapor Deposition", which means that the deposition process is carried out without chemical reaction by transporting the metal which has been previously transformed into a vapor phase from a source and which is condensed or implanted on the part to be covered by means of physical plasma phenomena.

Vacuum PVD deposits include several techniques, one of which is widely used in the industrial world and in Materia Nova and is called "cathodic magnetron sputtering".

Vacuum deposition applications are an integral part of our lives, and we find them in the electronic, optical, mechanical and decorative industries, etc.

The subjects developed by this technology at Materia Nova are

- Protective coatings (anti-corrosion, wear resistance, UV resistance, hard coatings, tribological films, etc ...)

- Functional coatings (antimicrobial surfaces, optical properties, easy to clean, TCO and conductive coatings, hydrophobic, hydrophilic, barrier effect (gas, water,...), energy management, etc ...)

- Active coatings (sensors, catalysis, etc ...)

- Etc...
