“…The most commonly used molds/punches are considered to be of graphite for most of the composites and generally graphite sheets are used as a shroud between the sample and the mold-die punch to prevent the sticking of the sample and mold/punch for further use. 11,[68][69][70][71][72][73][74][78][79][80][81][82][83][84][85][86][87][88] The SPS process is entirely divided into four main stages which are (a) removal of gases from the chamber and generation of vacuum, (b) the two intermediate stages involves the simultaneous application of resistance heating and applied pressure, (c) cooling of sintered samples. 75 The existence of spark plasma and the occurrence of discharge have been a controversial issue and highly debatable in SPS sintering process.…”

“…SPS is an advanced and novel method of sintering process that offers many advantages over conventional sintering techniques such as higher heating rates, shorter holding times, and comparatively lower sintering temperatures. 73–94 The typical SPS system consists of a mechanical loading system, an electric current generator, vacuum/atmosphere chamber, and a water cooling apparatus as shown in Figure 3. 67…”

The high-performance tool materials have been inevitably used for most of the cutting tool applications where high reliability and difficult to cut materials are of major demand. The cemented carbides and its composites offer an excellent combination of the properties where it can be used for tool materials due to its high wear resistance, high hardness at elevated temperatures, and considerable fracture toughness. However to obtain optimum values of mechanical properties and uniformly distributed ultrafine grains, a number of new fabrication techniques, alteration in the content of cemented carbide composition, and variation in the parameters of fabrication process have been employed. This review paper will come in handy for researchers and scientists working on advanced cemented carbides and spark plasma sintering as it overviews the recent work done on tungsten carbide composites using the novel spark plasma sintering technique considering different process parameters in order to achieve ultrafine microstructures of sintered specimens, enhanced mechanical properties of composites in addition to energy as well as time saving considerations. The thorough review of various research papers revealed that the parameters of the sintering (sintering temperature, applied pressure, surrounding environment), additives in sintering (both content and composition), reinforcement of cemented carbide with other materials, nano-filler/whisker addition, partial or complete removal of metallic phase from the cemented carbide affect the properties of sintered specimens and their calculated as well as optimum setting can provide an excellent combination of properties desired in cutting tool operations.
