Black pvd

Black PVD (Physical Vapour Deposition) coating is applied onto SS316L body jewelry.

The jewelry is coated in a heated chamber under high vacuum.
Electric voltage applied will form a plasma in the chamber and the introduction of various gases produces an ion bombardment.
This bombardment atomizes the cathode material into tiny substances, which are deposited on the jewelry.
The result is a hardened layer, which is biocompatible. It can be autoclaved.
