Abstract |
Multilayer nanostructured coatings consisting of alternating MoN and CrN layers were obtained
by vacuum cathode evaporation under various conditions of deposition. The transition from micron sizes of
bilayers to the nanometer scale in the coatings under investigation leads to an increase in hardness from 15 to
35.5 GPa (with a layer thickness of about 35 nm). At the same time, when the number of bilayers in the coat-
ing decreases, the average Vickers hardness increases from 1267 HV0.05 to 3307 HV0.05. An increase in the
value of the potential supplied to the substrate from –20 to –150 V leads to the formation of growth textures
in coating layers with the [100] axis, and to an increase in the intensity of reflections with increasing bilayer
thickness. Elemental analysis carried out with the help of Rutherford backscattering, secondary ion mass
spectrometry and energy dispersion spectra showed a good separation of the MoN and CrN layers near the
surface of the coatings. |
