Abstract |
The effect of the pressure of the nitrogen atmosphere during the formation of vacuum arc nitride
coatings based on high entropy alloys of the Ti–Zr–Hf–V–Nb–Ta system on their structure, hardness, and
tribotechnical characteristics is considered. It is shown that strong nitride forming components lead to the
dependence of the structural state and properties on the pressure of the nitrogen atmosphere during coating
deposition. Deposition at a nitrogen pressure of 0.4 Pa results in the formation of a texture with the [111] axis
when the applied bias potential is –70 V and when the bias potential is equal to –150 V the textural structure
is biaxial ([111] and [110]) textures and high value of hardness of 51 GPa Along with that the highest value of
wear resistance (under oxidizing mechanical wear) is inherent to coatings formed under the pressure of nitro
gen of 0.09 Pa. The strongest microdeformation of coating crystallites corresponds to this pressure. |
