“…3 that the addition of NbC or TaC results in a wear loss comparable to that of baseline TiCN–Ni cermet. Similarly, no observable influence of NbC/TaC addition on the erosion rate of TiCN–Co–Ni–WC cermets was reported in a previous work 17 . An important observation is that while considerable increase in erosive wear is measured for an increase in impact angle from 30° to 60°, such an increase is found to be relatively less for a further increase in impact angle to normal incidence.…”

“…In another interesting work, the hardness was not observed as a major factor in influencing erosion wear resistance of TiC‐based cermets; instead, the fracture resistance and modulus of elasticity were observed as important material properties affecting the erosive wear resistance 15,16 . However, D'Errico et al 17,18 . reported considerable influence of hardness on erosive wear of TiCN–Co–Ni–TaC/WC/NbC/MO 2 C cermets at both oblique and orthogonal impacts.…”

“…Because of potential tribological applications of cermet materials, research efforts have been invested to evaluate and understand the erosive wear properties of TiC‐, WC‐, Cr 3 C 2 ‐based cermets 10–18 . The erosion wear mechanisms of WC–Co and TiC‐based cermets are reported to be influenced by a combination of deformation and brittle fracture with more dominance of fracture behavior 11 .…”

The present communication reports the results of a first set of erosion wear experiments, conducted on TiCN-20 wt% Ni cermets containing different secondary carbides (WC, NbC, and TaC). The cermets are eroded by SiC particles (66 lm size) with a constant mass flow rate (2.33 g/s) at different angles of impingement (301, 601, 901) on an in-house fabricated erosion wear tester. An important experimental observation is that the investigated cermets exhibit behavior similar to ceramics, as evident from the systematic increase in erosion wear rate with impact angles. Among all investigated cermets, WC-added TiCN-20 wt% Ni cermets exhibit superior erosion wear resistance. SEM investigations of eroded surfaces (normal incidence) reveal grain pullout with intergranular fracture as the dominant material removal process.

“…7 is the average and standard deviation of three turning tests from three different inserts. The cutting performance of the NbC-Ti(C0.5N0.5) inserts is mainly driven by the Ti(C0.5N0.5) content, which controls the resistance to adhesive and abrasive wear [35]. The 32 and 42 Ti(C0.5N0.5) inserts exhibited a lower flank wear than the commercial Ti(C0.5N0.5) based insert.…”

In this study, Ni or Co + Ni bonded NbC matrix cermets with secondary carbides (Mo2C and WC) as well as Ti(C0.5N0.5) were prepared by liquid phase sintering at 1450°C in vacuum. Detailed microstructural investigation was performed by SEM, EPMA and XRD analysis. The microstructure, mechanical properties as well as the C45 (HB140) steel turning performance of the cermets were investigated, and compared with a commercial Ti(C0.5N0.5) based cutting insert. The sintering results indicated that the partial substitution of NbC by Ti(C0.5N0.5) had a significant effect on the core-rim microstructure and refinement of NbC solution grains, as well as improved mechanical properties of the NbC-Ti(C0.5N0.5) cermets. The phase constitution and composition of the cermets were supported by thermodynamic equilibrium calculations. All sintered cermets were composed of a fcc solid solution metal binder and a cubic core-rim (Nb,Ti,Mo,W)(C,N) solution phase, as well as an independent Nrich Ti(C,N) phase. The NbC-Ti(C0.5N0.5) and Ti(C0.5N0.5) matrix cermets had a comparable HV30 of 1500-1600 kg/mm 2 and a similar fracture toughness of 8.0 MPa m 1/2 .

“…Cermet tools have low affinities with work materials, but are mainly used for finish machining because they are low in toughness [9][10]. In terms of suppressing adhesion, the productivity of duplex stainless steel parts would be improved if cermet tools could be used effectively for rough or semi-finishing machining.…”

X2CrNiMoN25-7-3 duplex stainless steel is suitable for chloride-containing environments such as seawater because it has excellent pitting corrosion resistance. Duplex stainless cast steel is often used to accommodate the complexity of part geometry at joints. However, machining after casting is indispensable. This study evaluated the cutting characteristics of stainless cast steel. Adhesion of the cutting edge was weak at high cutting speeds, but tool wear was large. Diffusion and reactions between the work-pieces and the tool edge were investigated. Slight inter-diffusion and a reaction phase were observed, but the bond-ability was low.
