The effect of the deposition parameters of nitrides of high-entropy alloys (TiZrHfVNb)N on their structure, composition, mechanical and tribological properties

Influence of residual pressure and ion implantation on the structure, elemental composition, and properties of (TiZrAlYNb)N nitrides

“…It is seen that the respective values differ substantially. Such a difference causes strong lattice distortions and thereby influences the stress-strain state of the nitride HEAs, as was shown in [4,8,26]. In addition, Table 2 gives the values of the enthalpy and entropy of forma tion of the binary nitrides [27].…”

“…They offer excellent physicome chanical properties (hardness and Young's modulus), tribological properties (wear resistance, low friction coefficient, etc. ), and high thermal stability [4][5][6][7][8][9][10][11]. This is explained by the deformation hardening effect observed in solid solutions, crystal lattice distortions, and the formation of a nanocomposite structure (as well as in the case of nitride systems with a smaller amount of elements) [12][13][14][15][16][17][18][19].…”

Improvement of energy efficiency in the operation of a thermal reactor with submerged combustion apparatus through the cyclic input of energy

“…This is the basis for the development of priority scientific practical direction in modern materials science -surface engineering [1]. Surface engineering combines methods of directed change in the physical and chemical properties of the surface layers of materials by deformation [2], modification [3], deposition of single-layered [4], multi-period [5], multi-element [6] coatings and protective layers by different combined methods [7]. Innovative character of the surface engineering development is determined by the fact that the main quality indicators of machines are reliability and performance efficiency.…”

Results of approbation of the innovative method of ion nitriding for steels with low temperatures of tempering

“…Practically all criteria of working ability are determined by the properties of surface layers -they in particular must be improved first of all [1,2]. In this case, high surface hardness in the presence of large tensile stresses leads to brittle failure and crumbling, thus enhancing abrasive wear [3], and large compressive stresses -to plastic deformation of the base and its flow [4].…”
