“…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.…”

“…Wang et al 80 in 2020 studied the cutting performance and mechanisms of failure of ultrafine cemented carbides sintered by SPS in dry turning of Ti-6Al-4V on CNC lathe. The SPS fabricated tools with composition (WC-8wt%Co) and (WC-8wt%Co-0.2 wt%VC-1.0wt% cBN) showed better life and higher processed quality than the commercially used (WC-8 wt%Co) composite tool.…”

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.

“…Additionally, sharp cutting edges can be created using ultrafine cemented carbides, which lower cutting pressures and tool temperatures while enhancing surface smoothness. 26 Wang et al 27 investigated the cutting performance and failure mechanisms of ultrafine cemented carbide tools in the dry turning of titanium alloys. They discovered that employing ultrafine WC-Co tools resulted in better tool life and machined surface quality than conventional cemented carbide tool, with the cutting distance being 1.6-1.8 times longer than that.…”

Ultrafine tungsten carbide (WC)–cobalt (Co) and WC–(Ti,W)C–Co end mills were produced via spark plasma sintering. The wear mechanism of these end mills during machining of AISI H13 steel was investigated. WC–Co exhibits good mechanical properties (HV30: 2110 kg/mm2, KIC: 10.4 MPa/m1/2, TRS: 1990 MPa). Although the high hardness of WC–Co makes it show excellent resistance to abrasive wear, it suffers from a significant adhesion problem. As the cutting temperature increases, the oxidation of the WC–Co causes damage to the microstructure of tool materials, which deteriorates the grain boundary strength and promotes adhesive wear. This phenomenon causes large areas of tool materials to chip off and eventually results in cutting‐edge breakage. The high brittleness of (Ti,W)C causes cracks to propagate at low‐stress levels, reducing the mechanical properties of WC–(Ti,W)C–Co (KIC: 8.8 MPa/m1/2, TRS: 1090 MPa). However, (Ti,W)C addition enhances the resistance to oxidation and workpiece adhesion, which reduces the tool material loss caused by adhesive wear. The tool life of WC–(Ti,W)C–Co is three times longer than that of WC–Co in milling of AISI H13 at the same cutting speed. The key to maximizing the mechanical properties of ultrafine cemented carbide tools when machining AISI H13 is the modification of anti‐adhesive wear of surface.
