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

Coating thickness        0.5 – 10 µm

Hardness              1,000 – 4,000 HV

Temperature resistance    300 – 1,150 °C

Deposition temperature   200 – 600 °C

Coating structures

  • Multilayer
  • Nanocomposite layer
  • Monolayer
  • Gradient layer
  • Micro alloyed layer

Advantages

  • Excellent coating adhesion even with low coating temperatures;

  • High production output, suitable for serial production;

  • Flexibility for different component shapes, sizes, and quantities;

  • Strong wear protection with low friction values;

  • Superior hardness, oxidation resistance, and reduced chemical reaction.

Typical applications

  • Cutting tools
  • Primary shaping, forming, and forging tools
  • Plastic processing tools
