Proprieties and deposition technique for Nanostructured PVD coating The NANOSTRUCTURED coatings can be designed in such a way as to have very high values of hardness, wear resistance, corrosion, thermal oxidation and low friction coefficient. These and other properties (such as biocompatibility and catalytic ones) can be combined in a single multifunctional nanostructured coating. PRODUCTION TECHNIQUE Thermal Spray ( HVOF, Plasma, Arc) Sol Gel Physical Vapor Deposition ( Arc, Sputtering) Chemical Vapor Deposition Laser Deposition Elettrodeposition 3
