“…The intensity of CrSi 2 was the highest in SN05 which has improved the hardness value and the intensity of CrSi 2 phase was less in SN10; as a result, the hardness value decreased. The SN05 has a greater hardness as compared to the value reported by Shankar et al [8] and Lv et al [19], Ragothuman et al [20] and Xavieret al [21]. The present cermet composition 85%TiCN-5%C-5%Cr 3 C 2 -5%Si 3 N 4 (SN05) showed outstanding hardness value.…”

A TiCN-Co-Cr 3 C 2 -based cermet, with the addition of 5wt. % and 10wt. %Si 3 N 4 and a reference sample without Si 3 N 4 addition were prepared by the spark plasma sintering technique. The average hardness and fracture toughness of the 90TiCN-5Co-5Cr 3 C 2 (SN00) cermet-sintered specimens were e14.85±3.11 GPa and 6.78±0.61 MPaÖm, respectively. The cermet composition 85TiCN-5Co-5Cr 3 C 2 -5 wt. % Si 3 N 4 (SN05) enhanced the hardness and fracture toughness to 20.90±0.825 GPa and 7.23±0.45 MPaÖm, respectively. Further addition of 10 wt%Si 3 N 4 with 80TiCN-5Co-5Cr 3 C 2 (SN10) decreased the hardness value to 16.18±0.279 GPa due to a decrease in the density of defects. However, the fracture toughness steadily increased to 9.34±3.10 MPaÖm. The cermet composition 85TiCN-5Co-5Cr 3 C 2 -5Si 3 N 4 (SN05) showed an appreciable improvement in hardness and toughness values due to the formation of a core-rim structure, with the core consisting of TiCN and the rim with TiN,

“…These cermets exhibit higher red hardness, higher wear resistance, and better thermal stability compared to conventional WC-Co cemented carbides, offering advantages in terms of resource reserves [5,6]. Therefore, Ti(C,N)-based cermets are considered an ideal alternative to WC-Co in the field of wear-resistant materials and tool materials [7,8]. However, the wide range of applications of cermets is limited by their low toughness.…”

The use of metal-coated ceramic powders not only effectively enhances the wettability of the metal–ceramic interface but also promotes a more uniform microstructure in Ti(C,N)-based cermets, which is advantageous for improving their mechanical properties. In this study, ultrafine Co- and Ni-coated (Ti,W,Mo,Ta)(C,N) powders were synthesized via the spray-drying-in-situ carbothermal reduction method. Subsequently, Ti(C,N)-based cermets were effectively fabricated using the as-prepared ultrafine Co- and Ni-coated (Ti,W,Mo,Ta)(C,N) powders. The impact of reaction temperature, heating rate, and isothermal time on the phase and microstructure of prepared powders was analyzed using X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Additionally, the microstructure of the as-sintered cermets was experimentally investigated. The findings reveal that the complete reduction of Co and Ni metal salts, pre-coated on the surface of (Ti,W,Mo,Ta)(C,N) particles, can be achieved through rapid heating (10 °C/min) in a specific temperature range (600–1000 °C) with an isothermal time of 3 h at a lower reduction temperature (1000 °C). The synthesized powders have only two phases: the (Ti,W,Mo,Ta)(C,N) phase and Co/Ni phase, and no other heterogeneous phases were observed with an oxygen content of 0.261 wt.%. Notably, the conventional core–rim structure was not dominant in the cermets obtained from the prepared Co- and Ni-coated (Ti,W,Mo,Ta)(C,N) powders. Moreover, the heterogeneous segregation effect of the Co/Ni coating on the ultrafine powder particles resulted in a finer microstructure than the traditional cermets with the same composition. However, the grain size is mainly in the range of 0.5–0.8 μm. The weaker residual stresses at the core and rim interfaces and the finer particle distributions could theoretically enhance the toughness of Ti(C,N)-based cermets, simultaneously.

Sintering kinetics of NiFe 2 O 4 -based ceramics inert anodes for aluminum electrolysis doped 7 wt% TiN nanoparticles were conducted to investigate densification and grain growth behaviors. The linear shrinkage increased gradually with the increasing sintering temperature between 1000 and 1450 • C, whereas the linear shrinkage rate exhibited a broad peak. The maximum linear shrinkage rate was obtained at 1189.4 • C, and the highest densification rate was achieved at the relative density of 75.20%. Based on the pressureless sintering kinetics window, the sintering process was divided into the initial stage, the intermediate stage, and the final stage. The grain growth exponent reduced with increased sintering temperature, whereas the grain growth activation energy decreased by increasing sintering temperature and shortening dwelling time. The grain growth was mainly controlled by atomic diffusion. NiFe 2 O 4 -based ceramics possessed hightemperature semiconductor essential characteristics. The electrical conductivity of NiFe 2 O 4 -based ceramics first increased and then decreased with increasing sintering temperature, reached their maximum value (960 • C) of 33.45 S/cm under 1300 • C, mainly attributed to the relatively dense and uniform microstructure. The thermal shock resistance of NiFe 2 O 4 -based ceramic was improved by a stronger grain boundary bonding strength and lower coefficient of linear thermal expansion.
