Abstract |
The formation of a phase with a FCC lattice of the NaCl structure type is observed following the
deposition of a multielement nanostructured (TiZrHfVNbTa)N coating. An increase in pressure results in a
change in the preferred orientation of crystallite growth from the [100] axis perpendicular to the growth plane
to [111]. The implantation of negative Au– ions with a dose of 1 × 1017 cm–2 and a concentration of 2.1 at %
leads to the formation of a disordered polycrystalline structure with no preferred orientation of the FCC
phase, reduces the size of nanocrystallites from 8 to 1–3 nm in a layer with a depth of up to 30–35 nm, and
increases the nanohardness to 33.0 GPa. The large difference in atomic radii of refractory metals and the
reduction in the size of nanograins in the coating contribute to an increase in hardness (51 GPa). |
