CrN (Chromium Nitride)
Anticorrosion
Chromium Nitride or CrN is able to express a considerable hardness. Together with a very tenacious structure, it is possible to obtain layers with much higher thicknesses than all other coatings (up to 15 microns). This advantage together with the excellent resistance to corrosion make CrN an extraordinary barrier to chemical aggression and oxidation. CrN is also biocompatible and suitable for food contact.
