Microstructure and its defect analysis of titanium nitride and chromium nitride multilayer tribological systems
Multilayer tribological coatings on Ti/TiN; 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 µm. Microstructure was studied using conventional and high resolution transmission electron micro[...]
Optimization of Ti - Cr - N multilayer wear resistance coatings through microstructure control
In the current work, 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 . In the case of Cr/CrN, metallic layers are tough but soft and nitride layers are hard but [...]
