Phase composition and properties of wear resistant Ti-Al-Cr-Zr-Nb-N coatings manufactured by the arc-physical deposition method

The structure and properties of high-entropy alloys and nitride coatings based on them

“…38 A distinctive feature of this method consists in higher energy of particles deposited compared to magnetron sputtering. Studies of the phase composition of the coatings revealed two phases based on ZrN and on TiN; other metals (Al, Cr and Nb) seem to dissolve in these two nitrides.…”

“…38,42 The coatings (TiAlCrZrNb)N exhibited high hardness (H) which varied from 26.1 to 36.6 GPa as the negative substrate bias potential increased from 780 to 7120 V. As the bias potential changed to 7160 V, the hardness of the coatings decreased owing to relaxation of internal stress produced by increase in temperature caused by increase in energy of ions being deposited. These coatings were characterized by high wear resistance coefficients (up to 5.45).…”

Research of mechanical and cutting properties, wear and failure mechanisms of nano-structured multilayered composite coating Ti-TiN-(NbZrAl)N

“…A series of studies have tested the properties of multicomponent nano-structured coatings [9][10][11][12]. Braic et al [9,10] studied the properties of nitride system (TiZrNbHfTa)N, which composition, in addition to Zr, Nb and Ti, also includes Hf and Ta.…”

“…Braic et al [9,10] studied the properties of nitride system (TiZrNbHfTa)N, which composition, in addition to Zr, Nb and Ti, also includes Hf and Ta. Pogrebnjak et al [11] and Blinkov et al [12] considered the study of the properties of multi-composite coatings on the basis of nitride systems (TiHfZrVNb)N, which composition also includes Hf and V, as well as systems (TiAlCrZrNb)N and (TiAlCrZrNb)N, which composition is modified through introduction of Al and Cr. It should be noted that the above studies were focused only on coatings with mono-layered architecture, including coatings with nano-scale structure.…”

“…Out of various types of wear-resistant coatings, developed and implemented in recent years, multilayered composite coatingswith gradient structure, as well as multi-component coatings should be noted [1][2][3][4][5][6][7][8][9][10][11][12][13][14].…”
