PVD Coating Technology
What is PVD Coating Technology?
PVD is the abbreviation of Physical Vapour Deposition. PVD coating is a plasma coating deposition technology.
Vacuum Coating
The materials are vaporized under vacuum coating conditions to obtain a PVD coating. A vacuum chamber is necessary to avoid reaction of the vaporized material with air.
Features
PVD coating is used to provide new, additional features to the product: PVD coatings can have a vivid colour, there are wear resistant PVD coatings or reduced friction PVD coatings. PVD coating technology is a thin film coating in an environmentally friendly process.
Process basics
