PVD coating

PVD stands for "Physical Vapour Deposition“.

The Arc method is a commonly used Physical Vapor Deposition (PVD) process for depositing nitride hard coatings in industry.

In the Arc method, a high-purity metal such as titanium or chromium is evaporated by an electric arc and reacts with the reaction gas in a high vacuum to deposit a thin, extremely durable and hard wear protection layer on the substrate surface.

This PVD process is the final step in optimizing tools before they are used in the production process, and the low process temperature below 500°C ensures no influence on the microstructure of the tool steels, no deformation or hardness drop. For special low-alloy materials or non-ferrous metals, a further reduction in coating temperature is possible.

Advanced plant technology enables the deposition of duplex and hybrid coatings.

Technologie

Materials that can be PVD coated:

  1. Conductive materials
  2. Temperature and heat-resistant > 500°C (process temperature)

Examples: Cold- and hot-working steels, high-speed steels, powder metallurgical steels, hardening steels, corrosion-resistant steels and hard metal

On request:

  1. Low-alloy steels
  2. Reinforced tools
  3. Screwed or pressed tools
