Calico D-2 (nACRo) PVD Coating


Calico D-2 is a Nanocomposite structure. This is accomplished by embedding nanocrystalline AlCrN grains into an amorphous matrix. This advanced Nanocomposite Technology has allowed the formation of a higher nanohardness coating with greater thermal stability than any conventional coating. Typically used in extreme environments and metal-on-metal wear. Calico D-2 is normally applied to steels and hardened steels materials where high wear resistance is needed. Can be stripped and recoated.

Calico D-2 is applied using lateral rotating cathode technology in a PVD (physical vapor deposition) process. Material is vaporized from a solid source in the form of atoms/molecules and then transported in the form of a vapor through a vacuum, low pressure gas/plasma to the substrate where it condenses. Calico-D-2 application temperature is 450°C.
