“…Hard nanocomposite coatings for cutting tools may generally be classified into two groups: [137], nc-TiC + a-C [138,139] Ti-Si-N [140,141], Ti-Si-B-C [142][143][144], Ti-Si-B-C-N [145], AlTiN-Ni [146], ZrN/SiN x [147], nc-W 2 N/a-Si 3 N 4 [148], (Zr-Ti-Cr-Nb)N [149,150], Mo 2 BC [151], nc-AlN/a-SiO 2 [152]. In particular, several of these coatings, such as Ti-Al-Si-N, Ti-Si-N and AlTiN-Ni, were deposited and tested on cemented carbide WC-Co-based substrates like in [135,136,140,146].…”

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.

“…Application of protective coatings may bring an increase of corrosion and chemical resistance [66,67], increase of working temperature of the products [68], improved wear resistance [69,70] and, thus, longer lifetime of the product. Very high interest nowadays is on multi-layered structures [71][72][73] and high entropy alloy (HEA) coatings [73,74].…”

Hybrid additive manufacturing is a relatively modern trend in the integration of different additive manufacturing techniques in the traditional manufacturing production chain. Here the AM-technique is used for producing a part on another substrate part, that is manufactured by traditional manufacturing like casting or milling. Such beneficial combination of additive and traditional manufacturing helps to overcome well-known issues, like limited maximum build size, low production rate, insufficient accuracy, and surface roughness. The current paper is devoted to the classification of different approaches in the hybrid additive manufacturing of steel components. Additional discussion is related to the benefits of Powder Bed Fusion (PBF) and Direct Energy Deposition (DED) approaches for hybrid additive manufacturing of steel components.* e-mail: vvp@technion.ac.il Rev. 7, 6 (2020) This is an Open Access article distributed under the terms of the Creative Commons Attribution License (https://creativecommons.org/licenses/by/4.0), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.

“…That's why for protective coatings it is both crucial to have high hardness and toughness. The nitrides of transition metals are the best candidates to occupy the leading positions in satisfying such requirements [33][34][35][36][37][38][39][40][41][42]. Their study and development is an actual task of material science and engineering.…”

The paper is focused on the deposition and study of multilayered transition metal nitride films CrN/MoN obtained by vacuum arc deposition (Arc-PVD). Samples have from 12 up to 354 layers with total thickness of 8-15 μm. Bilayer thickness of samples vary in range from 2.2 μ to 40 nm. Films have been studied by scanning electron microscopy (SEM) from crosssection view. Their elemental composition also has been studied by energy-dispersive X-ray spectroscopy (EDS). Characterization of the structure of multilayered CrN/MoN films have been performed using X-ray diffraction (XRD) analysis. Two main phases of cubic CrN and-Mo2N have been identified. Grain size distribution was calculated from XRD analysis data. It was observed the decreasing of average grain size with decreasing of individual layer thickness. This feature of studied films may be important for characterization and prediction of their mechanical properties, such as hardness, elasticity, toughness etc. According to the Hall-Petch strengthening, deposited films with lower values of individual layer thickness may have higher values of hardness and, hence, exhibit better toughness, wear resistance and improved performance of coated tools.
