Surface engineering

Supports the design of mechanical components

Surface engineering offer is addressed at assuring technological innovation for such industrial sectors as steel, transportation, oil & gas, aerospace & defence and renewables.

RINA develops high performing solutions for wear and friction, corrosion, thermal insulation, catalysis, radiation absorption and good-looking surfaces, up to the selective interaction with chemical compounds.

The rich provision of pilot scale equipment assures the possibility of handling and managing all classes of materials (metallic, composite, ceramics, semiconductor, etc.) and the adoption of the best-fitting process / material compromise for any specific application.

Finally, through our tribology laboratory, we provide organisations with a nimble testing structure designed to characterise materials and surfaces.

Focus on lab & facilities

We rely on advanced facilities for the surface modification of components and of presently developed structures. Some of these are:

Cold gas spray (CGS)

A deposition system using CGS has been installed at the research unit of Lamezia Terme (Calabria, Italy). The GCS technique allows to deposit metal coatings on mechanical components, to protect them from wear and corrosion.

Plasma spray (PS)

This facility handles any type of material, by selecting the best operational practice in terms of coating quality and adhesion to substrates.

Equipped with a process chamber which permits to create different operational conditions, the facility can be managed in four different ways: Air Plasma Spray (APS), Vacuum Plasma Spray (VPS), High Pressure Plasma Spray (HPPS) and Controlled Atmosphere Plasma Spray (CAPS). The coatings’ thickness normally ranges between 0.5-1 mm, although higher thickness is also achievable in a reliable way by adopting stress-relieving post-treatments.

High velocity oxy fuel (HVOF)

This is an industrial-sized deposition equipment, operated thanks to a multiaxial robot. Different from the plasma spray technology, HVOF uses kerosene combustion as its thermal source and produces process gas, reaching exit speeds of about 5 Mach, thus guaranteeing full-density coating. HVOF’s coating thickness ranges around 0.5-2mm and it can manage 500*500*500 mm sized pieces.

Plasma transferred act (PTA)

This facility allows to reach a coating thickness that ranges between 0.5-5 mm by handling both flat and cylindrical pieces whose maximum length and width (or diameter) can be, respectively, 1000 mm and 400 mm.

Plasma assisted physical vapour deposition (PA-PVD)

This facility is based on two source modes: arc and RF sputtering. It is able to deposit both stoichiometry- and microstructure-controlled single and multi-layer coatings, and co-deposited materials; nanostructured coatings can be synthetized, too. The coating thickness achievable through PA-PVD also depends on the source mode adopted.

Electron beam physical vapour deposition (EB-PVD)

This facility features a deposition chamber of 4.5 m3 in volume, and is endowed with such devices as an 80 KW electron gun, a max 10 KW magnetron sputtering and a 3 KW ionic gun.

Plasma-assisted chemical vapour deposition (PA-CVD)

This laboratory scale equipment features a low-volume reaction chamber, where the feed-gases are excited and ionized through a magnetron source largely employed for the development of DLC (Diamond-Like-Coating) and diamond coatings.

Tribological coatings
