For over 30 years, voestalpine eifeler has created the most innovative PVD coatings on the global market today. Eifeler PVD coatings are ceramic thin films that help protect your substrate by adding hardness, lubricity, and a shield against high working temperatures.
PVD Coatings – HPDC
PVD COATINGS
Physical vapour deposition (PVD) is used to describe any of a variety of methods to deposit thin films by the condensation of a vaporized form of material onto various surfaces. The metallic elements of the layers consisting of titanium, chrome and aluminum, make a connection to nitrogen and carbon under the impact of a plasma and temperatures of 200 °C to 500 °C. They provide a strong ceramic in this way. The hardness of generated layers are in a range of 1000 to 3800 HV, the coating thickness is between 1 to 10 µm, depending on use.
The PVD hard material coating is carried out at eifeler almost exclusively by means of arc vapor deposition (electric arc vapor deposition ) with temperatures < 450 degrees centigrade. With the arc process technology an excellent adhesion is achieved without hardness loss, distortion or change of the micro-structure of the base material.

The following advantages result for you:
- Possible combinations with friction reducing layers
- Variable coating structure (nanostructures, multi-layer, monolayer)
- Decoating by chemical and mechanical means
- Very good adhesion on the substrate
- Very good reproduction of textured and polished surfaces
- Very good maintenance of dimensional accuracy and contour-true coating
- No hardness reduction
- No influencing of the crystalline structure of the steel with suitable material selection

TIGRAL – Abrasion resistance and high thermal resistivity
This coating, based on AlCrTiN, is characterized by its high hot hardness and its resistance towards oxidation and abrasion. These properties are the result of its nanostructure, which minimizes crack propagation within the coating, especially when subjected to shear loads.
