Microstructural Evolution and Properties in Ti(CN)-Co/Ni Cermet Depending on the Starting Material for Incorporation of WC

Investigation into the microstructure and cutting performance of (Ti,Ta,W)(CN)–Co/Ni cermets

“…Similarly, it was reported that the room temperature hardness and fracture toughness of (Ti,W)(CN)-Co/Ni cermets were enhanced by the addition of WC up to 30 wt.% [6]. Fig.…”

“…WC is a primary additive for cermet because it can improve wettability, sinterability and mechanical properties [3][4][5][6][7][8]. There is, however, a lack of studies into the effects of different starting materials containing WC additives on the microstructures and mechanical properties of TiCN-based cermets.…”

“…The incorporation of nitrogen (TiN and TiCN) and/or other carbides (WC, TaC, Mo 2 C and NbC) besides the main components of cermet TiC has been employed to enhance chemical stability and mechanical properties, especially fracture toughness [3][4][5][6][7][8][9]. When the nitrogen is incorporated into a TiC-based cermet, the fine-grained structure of the carbonitride phase improves hardness and chemical stability [8,9].…”
