Superlattice

Universal coating based on 1200 alternating nanolayers of chromium nitride and niobium nitride, for general molding

The Superlattice Lafer coating for molds is the CrN evolution, with an incredibly higher wear resistance.
Superlattice is the final patented result of a six-years project leaded by a group of thirteen European researchers, including Lafer, Bosch, Daimler Benz, Sheffield University, Manchester University and many others.
Characterised by a structure of 1200 alternating layers of chromium nitride (CrN) and Niobium nitride (NbN), has a hardness of over 2500HV, a friction coefficient of 0,4, a coating temperature of 280°C, and can be used in a variety of mechanical and molding applications, with working temperatures less than 850 C. Deposited at low temperature, Superlattice Lafer has the great advantage that it can be applied to practically any type of metallic substrate. Suitable for use of medical devices in accordance with the ISO 10993-5:2009 norm, it is also suitable for contact with food as per REG EU 1935/2004.
