PVD coating

In the PVD technique, the desired coating material is brought into a gaseous state and applied to the blade. After the material has then condensed, it forms the target layer, i.e. the additional surface layer. The coating ensures that the blade does not wear out too quickly and at the same time gives it corrosion resistance and improved hardness. PVD-coated blades also have better gliding properties because they have a lower coefficient of friction. Typical materials often used for PVD coatings are titanium carbonitride (TiCN), titanium nitride (TiN) and titanium aluminium nitride (TiAlN).
