Nanocomposite nc-TiAlSiN and nc-TiN-BN coatings: their application on substrates made of cemented carbide and results of cutting tests

Popis výsledku v původním jazyce

Nanocomposite coatings TiAlSiN and Ti/BN were deposited on indexable cutting inserts made of cemented carbide by plasma vapour deposition (PVD) and combined PVD/plasma activated chemical vapor deposition (PACVD) techniques. The Ti/BN coatings were prepare in two superhard forms: (1) TiN-BN nanocomposites with low residual internal stress and with the presence of a c-BN phase as determined by XRD; and (2) superhard Ti-B-N coatings with very high residual internal stress and with only one crystalline phase detected by XRD. Their properties were evaluated. Nanocomposite monolayer TiAlSiN and Ti-B-N layer applied on the indexable inserts were compared in cutting tests. The nanocomposite multilayer TiAlSiN showed the best performance under conditions of high cutting speed, whereas the Ti-B-N coatings were more successful at lower cutting speed.
