Physical Vapour Deposition (also known as PVD) has become widely used at deposit wear resistant, thin film coatings onto medical devices, including heart pacemakers, surgical instruments, and other implants. The main value of PVD technology rests in the ability to modify the surface properties of a ring without changing the underlying material's properties and biochemical functionality while you wear your Navel Ring in piercing.
