Abstract |
It has been found that the phase with the fcc lattice of the NaCl structural type is formed due to
the vacuumarc deposition of the nanostructured multicomponent (TiZrHfVNbTa)N coating. Implantation
of negative Au– ions with a dose of 1 × 1017 cm–2 leads to the formation of a disordered polycrystalline struc
ture without a preferred orientation of the fcc phase and nanocrystallites from 5–7 to 1–3 nm is size, which
are dispersed in a layer up to 35 nm in depth. Nanohardness increases to 33 GPa, and the Vickers hardness
reaches 51 GPa. Gold nanoclusters are formed in the nearsurface region, while the fcc lattice and the for
mation of local Au regions are observed in the coating itself. Fragments with the hcp lattice are formed at
depths above 180 nm because of the low nitrogen concentration. |
