“…This significant difference could be related to the spark, which produces 2000 °C for less than a millisecond in a random small area. This condition could prevent crystallite growth or sometimes breaks large crystallite [26][27][28]. Fig.…”

Spark plasma sintering (SPS) is an advanced process of sintering materials at low temperatures and short time by creating spark plasma at very high temperatures in the small points and short times, by which materials with high sintering temperature can sinter at lower temperatures. In this study, alumina-nickel-cobalt composites were sintered by SPS and RHP (rapid hot press) methods to investigate the effects of electric pulse on their microstructure and mechanical properties. To this end, sample powders containing alumina, nickel-cobalt aluminate spinel, and aluminum were sintered at 1380 °C under 30 MPa pressure for 10 min by SPS and RHP and then investigated. The densities of both samples were about 98% of theoretical density. Also, hardness and fracture toughness of both samples were about 11 GPa and 14 MPa.m0.5, respectively. The bending strengths of the SPS and RHP samples were 380 and 336 MPa, respectively.

“…Strictly speaking, the majority of nanocomposites investigated to date are composites with microcrystalline matrices and nanoscale secondary phases (Sergueeva et al, 2009;Tokita, 2013;Golla and Basu, 2014). Very few truly nano-nano composites have been investigated, and this presents a great opportunity to generate property and microstructural data for truly nano-nano composites using SPS technology.…”

“…The particle shape and size of the second phase play a crucial role in the determination of the extent of toughening or strengthening in most nanocomposite materials (Sergueeva et al, 2009;Tokita, 2013;Golla and Basu, 2014). A number of technologically important groups of ceramic nanocomposites have been studied to date.…”

“…Thus the percolating pulsed current creates fluctuating hot-spots which are characterized by high local current densities at the contact points (Guillon et al, 2014). These hot-spots momentarily induce partial melting, recrystallization, and impurity vapourization during the ON-time and subsequently these liquidized surfaces are bonded by forming 'necks' during the OFF-time; this is enhanced by application of a uniaxial force (Aalund, 2008;Kessel and Hennicke, 2007;Kessel et al, 2009;Tokita, 2013) (Figure 3).…”

The consolidation of nano-sized composite materials presents a challenge using conventional hot pressing methods. Spark plasma sintering (SPS) technology has shown great promise in the successful sintering of nanoreinforced composite materials. This qualitative review seeks to impart knowledge gathered, and progress made over the years on the consolidation of nanocomposite materials using SPS technology. The review is aimed at introducing this technology to the South African science and engineering community. Emphasis is on improving the mechanical properties of structural ceramic nanocomposite materials, which over the years have shown great promise in a wide range of applications, including transport, energy, mining, and the environment. Although success has been achieved within the laboratory for research purposes, there are still great opportunities to commercialize the technology for the production of larger components with more complex shapes. ceramic nanocomposites, structural materials, spark plasma sintering, fracture toughness, ceramic matrix composites.

“…SPS is based on the idea of high-rate heating (up to 2500 о С/min) of materials (powders, bulk materials, composites) in vacuum or inert atmosphere by means of passing millisecond highpower pulses (up to 5000 A) of direct pulse current through samples and simultaneous pressure application [10]. Such a combination enables high-density structures in metals, alloys and ceramics [11][12][13].…”
