“…Hard nanocomposite coatings for cutting tools may generally be classified into two groups: [137], nc-TiC + a-C [138,139] Ti-Si-N [140,141], Ti-Si-B-C [142][143][144], Ti-Si-B-C-N [145], AlTiN-Ni [146], ZrN/SiN x [147], nc-W 2 N/a-Si 3 N 4 [148], (Zr-Ti-Cr-Nb)N [149,150], Mo 2 BC [151], nc-AlN/a-SiO 2 [152]. In particular, several of these coatings, such as Ti-Al-Si-N, Ti-Si-N and AlTiN-Ni, were deposited and tested on cemented carbide WC-Co-based substrates like in [135,136,140,146].…”
