PVD, which stands for Physical Vapour Deposition, gives the objects exceptional colours and shades. It consists of the deposition of metallic particles through vaporization in a vacuum chamber. The coating is welded on an atomic level to the stainless steel, giving the material greater hardness and resistance to rubbing and corrosion, thereby preventing the formation of rust or oxides. Thanks to the use of non-toxic materials such as titanium and zirconium, PVD is also used in the biomedical field as scalpels or surgical blades.
