How Does The PVD Coating Process Work?

Layering these materials (alternating Tin and TiCN) creates a composite structure with
enhanced properties. Many little layers are currently referred to 'nano layers' (10-9 meter in
thickness) while older or specific processes call for monolithic or mono-layered materials.
Mono-layered material is a single layer of a specific material while multi-layered or
nano-composite structures have a few to dozens of specifically tailored layers of material
to enhance certain material properties including controlling internal stresses.

In summary: Titanium or other certain metals are vaporized from a solid source (cathode)
by means of an electric arc to form a plasma vapor. The resulting, highly charged, metal ions
from the plasma are then mixed with inert gas such as nitrogen. The positively charged plasma
is attracted to the negatively charged substrate (object being coated) producing a thin, uniform,
colored metallic film on its surface.
