Abstract:

Multilayer coatings on Cr/CrN and TiN/CrN basis were deposited by the Pulsed Laser Deposition (PLD) technique at room temperature using an industrially designed 4-beam multi-spot PLD evaporator. Coatings were built of 2, 8, 32 and 64 layers with the total thickness of 1 m. Microstructure was studied using conventional and high resolution transmission electron microscopy (TEM, HRTEM). Examinations revealed that layers were built of columnar crystallites. Mechanical properties were analyzed using microhardness and scratch-test. Results showed that 8-layered coating exhibited optimal mechanical features in examined systems.
