Chromium Nitride (CrN) PVD Coating


Calico CrN (chromium nitride) is an excellent coating that provides lubricity and superior wear and corrosion resistance. Calico CrN has a very low residual stress, which provides for the best adhesion and ductility of any of the PVD coatings. High hardness, low coefficient of friction and the low residual stress of Calico CrN combine to resist abrasive, metal-on-metal wear, and galling. Calico CrN is an excellent coating for applications such as automotive parts, molds and dies, pump parts, shafts, dry deep drawing and works especially well when used against copper.

Calico-CrN 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. The standard process temperature is 425°C/750°F and provides the toughest coating. Low deposition temperature possible (220°C/420°F).
