“…It decreases regularly from C1 to C6 upon the increase in the carbon content ( Table 2). The SENB fracture toughness of C0 (10.3 MPa.m 1/2 - Table 2) is the highest among those reported for such a ceramic with an average grain size below 200 nm [9,[48][49][50], even when the measurements are made by the SEVNB method [15]. The fracture toughness of both C0.5 and C1 is still relatively high (about 7 MPa.m 1/2 ).…”

Double-walled carbon nanotube/yttria-stabilized zirconia composite powders with carbon contents up to 6.3 wt.% are prepared by soft covalent functionalization of carbon nanotubes (CNTs) followed by mixing with a nanometric yttria-stabilized zirconia (YSZ) powder. Composites are densified by spark plasma sintering (SPS). The composites present an electrical conductivity (0.09-0.88 S.cm -1 ) which is among the highest values reported in the literature. Both the fracture strength (V f ) and the single-edged notched beam fracture toughness (K Ic ) are measured for the first time on CNT/YSZ composites. The best mechanicalproperties (V f = 694 MPa; K Ic = 7 MPa.m 1/2 ), obtained for low carbon contents (up to 1.2 wt.%), are among the highest reported up to now. However, the fracture toughness is lower than that of the YSZ ceramic (K Ic = 10.3 MPa.m 1/2 ) whose mechanical properties are outstanding, taking into account its very fine microstructure.

“…Using the SPS process, research work on nanostructured materials and composite materials is very attractive and active to date. Many investigations on ceramics materials have been conducted [69][70][71][72][73]. Considering the effective SPS industrialization, as introduced in Figures 33, 35, 36 and 43, it is expected that the SPS 3D near-net/net shape forming method will be applied for parts production from R&D prototype level to practical mass production use in the near future [74].…”

The spark plasma sintering (SPS) method is of great interest to the powder and powder metallurgy industry and material researchers of academia for both product manufacturing and advanced material research and development. Today in Japan, a number of SPS products for different industries have already been realized. Today’s fifth-generation SPS systems are capable of producing parts of increasing size, offering improved functionality, reproducibility, productivity, and cost. For instance, pure nano-Tungsten Carbide WC powder (no additives) is fully densified with a nano-grain-sized structure for glass lens application in the optics industry. The SPS is now moving from scientific academia and/or R&D proto-type materials level usage to practical industry use product stage utilizing in the field of electronics, automotive, mold and die, cutting tools, fine ceramics, clean energy, biomaterials industries, and others. This paper reviews and introduces the peculiar phenomenon of SPS and the progress of SPS technology, method, development of SPS systems, and its industrial product applications.
