“…The degree of consolidation improved with an increasing amount of BG, and the 20%HA–80%BG composition displayed a full consolidation. In another work, Bertolete et al [170] fabricated functionally graded ceramic cutting tools using SPS. Two different FGCMs (Al 2 O 3 –ZrO 2 + WC–Co and Al 2 O 3 –TiC + WC–Co) consisting of six different layers were fabricated.…”

Monolithic components are often insufficient when a combination of conflicting properties, or a variation in properties at different regions within a material is required. Functionally graded composite materials (FGCM) are a relatively new class of materials with a systematic variation of the composition, microstructure, and properties along one direction. The graded structure offers tailorable property combinations not achievable with monolithic composites and significant recent research has been carried out on their development. An effort has been made in this article to review the latest developments on bulk FGCMs since 2015. The different processing techniques used for their fabrication have been discussed, highlighting their advantages, limitations, and recent advancements pertaining to FGCM fabrication. Various physical, mechanical, and thermal properties of FGCMs have been treated separately, and wherever possible, summary plots combining data from various research articles have been developed. Finally, potential areas for directing future FGCM research have been identified.

“…According to reviews [20,21], the most common method for manufacturing ceramic FGMs is powder metallurgy. It is not only technologically simple and reliable but also allows the mixing of the widest range of materials and controlling the microstructure and shape of products [22]. The desire to combine mutually exclusive (for conventional materials) properties in FGM causes the continuous development of new compositions and ratios of components, as well as the development and improvement of technological approaches and modes of their production.…”

The paper studies the structural features, phase composition and complex mechanical properties of two-layer composite ceramics based on alumina-toughened zirconia with silica added (Ca-ATZ/Ca-ATZ+SiO 2 ). The ceramics under study were manufactured using a costeffective technology involving grinding and mixing powders, layering of powder mixtures (different compositions), uniaxial pressing and two-stage sintering. It was found that at the interface of the compositions, there is an abrupt increase in fracture toughness (by 33%) and a decrease in hardness and Young's modulus (by 8% and 7%, respectively). The possibility of manufacturing composite ceramics Ca-ATZ+SiO 2 (with a thin surface layer, not containing SiO 2 ) with a high ratio of hardness (not lower than 14 GPa) and fracture toughness (not lower than 12 MPa m 1/2 ) was shown. Given the increased resistance to lowtemperature degradation of the developed ceramics, this will increase the service life of products operated under high mechanical loads in a humid atmosphere.

“…Si 3 N 4 -TiC ceramic composites [ 40 ] were prepared by adding TiC particles and gas-pressure sintering at 1750 °C, which achieved a fracture toughness of 8.4 MPa.m 1/2 . However, compared with synergistic reinforcements [ 30 , 41 ], the individual reinforcing approach is limited in terms of the enhancement of mechanical properties, no longer able to meet the harsh service conditions of Si 3 N 4 ceramic tool materials [ 42 ]. As a result, synergistic reinforcement is an effective method for preparing Si 3 N 4 ceramic tool materials with outstanding mechanical properties via hot-pressed sintering under low temperature and short holding time.…”

Si3N4 ceramic as a tool material shows promising application prospects in high-speed machining fields; however, the required high mechanical properties and low-cost preparation of Si3N4 ceramic tool materials restrict its application. Herein, synergistic reinforced Si3N4 ceramic tool materials were fabricated by adding β-Si3N4 seeds, inexpensive Si3N4 whiskers and TiC particles into coarse commercial Si3N4 powder (D50 = 1.5 μm), then sintering by hot-pressing with low temperature and short holding time (1600 °C—30 min—40 MPa). The phase assemblage, microstructure evolution and toughening mechanisms were investigated. The results reveal that the sintered Si3N4 ceramics with synergistic reinforcement, compared to those with individual reinforcement, present an enhancement in relative density (from 94.92% to 97.15%), flexural strength (from 467.56 ± 36.48 to 809.10 ± 45.59 MPa), and fracture toughness (from 8.38 ± 0.19 to 10.67 ± 0.16 MPa·m1/2), as well as a fine Vickers hardness of 16.86 ± 0.19 GPa. Additionally, the various reinforcement modes of Si3N4 ceramics including intergranular fracture, crack deflection, crack bridging and whiskers extraction were observed in crack propagation, arising from the contributions of the added β-Si3N4 seeds, Si3N4 whiskers and TiC particles. This work is expected to serve as a reference for the production of ceramic cutting tools.
