PVD coating

PVD (Physical Vapor Deposition) is a thin film coating process that produces finishes of pure metals, metal alloys and ceramics with a thickness, generally, between 0,3 to 1,5 μm.
This process is distinguished from others by its high quality and resistance to oxidation. In addition to the color and decorative appearance, the application of the PVD coating gives the pieces a thin ceramic layer of high purity, chemically inert and biocompatible.

As the name implies, this process involves the physical deposition of atoms through a cathodic arc, which consists of the evaporation of the material to be used as a coating through a high-power electric arc.
The combination of the three elements, gas, high temperature (150º C to 500º C) and electricity, provides materials with good adhesion to the substrate, increasing the durability and strength of the parts.
