Beschreibungen/Notizen

• Multielement nitride coatings of quasi-equiatomic compositions, (NbMoCrTiAl)N and (NbZrCu-TiAl)N, are synthesized by deposition on a substrate in vacuum from a multicomponent gas-metal plasma. This plasma is generated by a simultaneous independent vacuum-arc evaporation of the cathodes of the selected elements in a plasma-assisted mode in a nitrogen atmosphere. It has been established that the synthesized coatings are single-phase materials with a face-centered cubic crystal lattice. For the (NbZrCuTiAl)N coating composition, the crystal lattice parameter a = 0.44288 nm and for (NbMoCrTiAl)N – a = 0.40540 nm. The resulting nitride coatings have a nanocrystalline multilayer structure. Their microhardness depends on concentration and type of chemical elements, as well as on nitrogen pressure in the gas-metal plasma; it reaches 43 and 46.5 GPa for the (NbMoCrTiAl)N and (NbZrCuTiAl)N coatings, respectively.
