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
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.

CROSAL®-plus – That your tools withstand even highest temperatures
CROSAL®-plus is eifeler’s next generation AICrN based hard coating.
The new coating system is an advanced development of our well-established CROSAL® coating. As a result of optimized process parameters and a tailor-made coating microstructure this versatile high-performance coating covers all key requirements:
- High oxidation resistance.
- Outstanding hot hardness.
- Excellent coating adhesion.
Your plus in metal cutting
CROSAL®-plus is perfectly suited for challenging applications within the fields of dry cutting, punching and forming.
CROSAL®-plus is especially suited for the following applications:
Hardness: 3.200 ± 300 HV
Max. temperature of operation: 1100 °C / 2012 °F
Coefficient of friction against steel: 0.45
Coating thickness: 2-5 μm
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.
Hardness: 3,300 ± 300 HV
Max. application temperature: 900 °C / 1,652 °F
Coefficient of friction against steel: 0.6
Coating thicknesses: 3 – 5 µm
