“…Cemented carbides based on WC and a ductile metal matrix (Co, Ni and/or Fe) are used in a wide range oftribological applications such as cutting, mining, metal forming, drilling and turning [1], because of their good combinations of mechanical properties such as hardness, toughness, wear resistance and strength [1,2]. These properties depend mainly on the WC grain size, type and amount of binder [3], and thus to improve on the operation life of these cemented carbides, successful manipulation of these factors is required.…”

“…The SPSed material is observed to be dense, the cBN particles are firmly bound with the cemented carbide matrix, and only a few micro-pores are visible. As seen clearly from [15] explained the formation of the micro-pores. Although Co was mixed with WC powder and cBN particles at a lower rotational speed for 2 h, particle deformation and agglomeration will inevitably occur, which promoted the appearance of micro-pores during sintering.…”

Composites containing ultrafine tungsten carbide/ cobalt (WC-Co) cemented carbides and 30 vol% cubic boron nitride (cBN) were fabricated by spark plasma sintering technique. The effect of cBN particles on the densification behavior, microstructure, and mechanical properties of the composites were investigated. According to SEM observation of microstructure, cBN particles are uniformly distributed and have excellent bonding with the cemented carbide matrix. Xray diffraction analysis shows that there is no indication of phase transformation from cBN to hBN. The addition of very hard dispersed cBN to the WC-Co promotes an increase of hardness, but a decrease of flexural strength. The density and the hardness of cBN-WC-Co composites increase with the increase of the sintering temperature. However, it has the highest hardness of 2,170 HV at 1,370°C and then the hardness decreases with the further increase of the sintering temperature.

“…WC-Co/cBN composites have been considered as a next-generation material for use in cutting-tool edges and are characterized by an optimal combination of hardness and toughness. The major challenge in sintering these composites is to produce a well-bonded interface between the WC-Co matrix and cBN particles [28][29][30][31].…”

The Critical Raw Materials in Cutting Tools for Machining Applications: A Review

A variety of cutting tool materials are used for the contact mode mechanical machining of components under extreme conditions of stress, temperature and/or corrosion, including operations such as drilling, milling turning and so on. These demanding conditions impose a seriously high strain rate (an order of magnitude higher than forming), and this limits the useful life of cutting tools, especially single-point cutting tools. Tungsten carbide is the most popularly used cutting tool material, and unfortunately its main ingredients of W and Co are at high risk in terms of material supply and are listed among critical raw materials (CRMs) for EU, for which sustainable use should be addressed. This paper highlights the evolution and the trend of use of CRMs) in cutting tools for mechanical machining through a timely review. The focus of this review and its motivation was driven by the four following themes: (i) the discussion of newly emerging hybrid machining processes offering performance enhancements and longevity in terms of tool life (laser and cryogenic incorporation); (ii) the development and synthesis of new CRM substitutes to minimise the use of tungsten; (iii) the improvement of the recycling of worn tools; and (iv) the accelerated use of modelling and simulation to design long-lasting tools in the Industry-4.0 framework, circular economy and cyber secure manufacturing. It may be noted that the scope of this paper is not to represent a completely exhaustive document concerning cutting tools for mechanical processing, but to raise awareness and pave the way for innovative thinking on the use of critical materials in mechanical processing tools with the aim of developing smart, timely control strategies and mitigation measures to suppress the use of CRMs.
