Abstract	Increasing of the negative potential on the substrate during the deposition of high-entropy nitride coatings of (Ti-Zr-Hf-V-Nb)N system leads to formation of the texture along the [111] axis, followed by the growth of its excellence. Increasing of potential on the substrate also leads to increasing of the microhardness values of the coatings from 24.78 GPa to 27.36 GPa. Results of tribological tests showed that after applying the test nitride coatings on steel disc, its durability significantly increased. This suggests high protective properties of (Ti-Zr-Hf-V-Nb)N coatings. By varying the deposition parameters of highentropy nitride (Ti-Zr-Hf-V-Nb)N alloy, one can define structure and influence on the physical and mechanical properties of the investigated coatings.
