Deposition of monoatomic and compound metal layers by the dynamic ion mixing

The effect of nanolayer thickness on the structure and properties of multilayer TiN/MoN coatings

“…This can be attributed to the two stage pattern of for mation of the phase composition of nanostructured multilayer coatings [9][10][11][13][14][15]. At the onset of growth of Mo 2 N, the determining factor for nucle ation is the atomic sequence of the basic TiN lattice by local epitaxy.…”

“…At the onset of growth of Mo 2 N, the determining factor for nucle ation is the atomic sequence of the basic TiN lattice by local epitaxy. Thus, during growth of a molybdenum nitride layer, the cubic modification of γ Mo 2 N undergoes stabilization, which, under the action of structural macrostresses upon the achievement of a relatively large thickness, is accompanied by the removal of macrodeformation and the formation of an interface [9,10,15].…”

“…Therefore, the strength of the nanocomposite increases by pre venting grain boundary shearing (sliding). In terms of the Koehler model [9], valence charge transfer, nan ograin size reduction, and a decrease in the entropy of mixing is a possible mechanism for increasing the hardness of these heterostructures [3,8,[10][11][12][13][14][15]. The lowest wear was observed during deposition of layers with thicknesses of 2 and 10 nm; it was 0.148 and 2.327 × 10 -5 mm 3 N -1 mm -1 for the counterbody and the coating, respectively.…”
