At the nanometer scale multilayer nanostructured coatings show special properties due to the depositions
conditions. This paper presents results of TiN/MoN nanocomposites obtaining and their research.
Multilayer coatings based on TiN/MoN were deposited using vacuum arc evaporation cathode method (CPVD).
Total thickness range of obtained coatings was 2, 10, 20 and 40 nm. We used vacuum-arc device
“Bulat-6” for coatings deposition. Structure and properties of multilayer coatings were analyzed using XRD
(Bruker D-8 Advance) in Cu-Kα radiation, high resolution transmission electron microscopy (HRTEM system)
with diffraction CFEI EO Techai F200, SEM with EDX (JEOL-7001F). Scratch tests were carried out
using Rockwell-C diamond indenter (CSM Revetest Instruments) with a tip radius of 200 μm. Besides this,
ball-on-plate sliding test on UMT-3MT tribometer (CETR, USA) was used for additional investigation of
friction and wear.
This research allowed to reveal structural and properties depending on deposition conditions of
TiN/MoN multilayer coatings. The nanocomposite hardness value increases when monolayer thickness decreases.
This also reduced nanograins size. Measurement of the friction coefficient demonstrates smaller
values for multilayer system in comparison with TiN or MoN nanostructured coatings. Formation of a (Ti,
Mo)N solid solution and nanocrystals growing were observed during annealing.
