Abstract |
Multicomponent nanostructured coatings based on (TiZrNbAlYCr)N with a hardness as high as
47 GPa were obtained by cathodic arc deposition. The effect of partial nitrogen pressure PN (with constant
bias potential Ub = –200 V applied to the substrate) on the phase-composition variation, the size of crystallites,
and their relation to the microstructure and hardness was investigated. An increase in the nitrogen pressure
resulted in the formation of two phases with characteristic BCC (the lattice period is 0.342 nm) and FCC
lattices with averaged nanocrystallite sizes of 15 and 2 nm. At a high pressure of 0.5 Pa, crystallites in the FCC
phase with a lattice period of 0.437 nm grew in size to ~7 nm. The hardness of deposited coatings with larger
(3.5 nm) FCC-phase crystallites and smaller (7 nm) BCC-phase crystallites was enhanced considerably |
