“…Although they offer a good ratio of hardness to fracture resistance [1], cemented carbide cutting tools cannot meet the needs of modern wood processing. These tools suffer from problems of high friction, considerable thermal shock, and high-temperature oxidation in the cutting area during the working process [2]. The cutting of wood is very complicated, as the cutting speed is 5 to 20 times higher than that of conventional metal, and the high density of cemented carbide cutting tools can be dangerous when cutting at high speed [3].…”

In this work, the diamond-like carbon and titanium nitride (DLC/TiN) multilayer coatings were prepared on a cemented tungsten carbide substrate (WC—3 wt.% Co) using the cathodic vacuum arc physical vapor deposition (Arc-PVD) method and pulsed Arc-PVD method with a graphite cathode for the deposition of TiN and carbon layers, respectively. The structural and mechanical properties of the prepared coatings were studied, and different techniques, such as scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), Raman spectroscopy, and microindentation techniques investigated their microstructure, composition, and phases. The prepared coatings had a multilayer structure with distinct phases of DLC, TiN, and carbide substrate. The potentiodynamic polarization method (PDP) was performed for the DLC/TiN multilayer coatings in 3% NaCl solution to evaluate the corrosion resistance of the prepared coatings. It has been shown that the DLC layer provided the coating with a polarization resistance of 564.46 kΩ. Moreover, it has been demonstrated that the DLC/TiN coatings had a high hardness of 38.7–40.4 GPa, which can help to extend the wood-cutting tools’ life.

“…As a hypoallergenic metal, it has been employed in jewelry and coin manufacturing technologies [1]. As a light-ductile metal, it has a wide range of applications in superconducting radio frequency (SCRF) technology [2,3], nuclear reactors, chemical processes [4], energy storage [5][6][7], cutting tool substrate in the form of carbide [8], etc. Niobium is usually covered with a dense layer of oxide, thereby providing a high level of corrosion resistance.…”

“…Basic hardmetals (also known as cemented carbides) and cermets consist of hard carbide phases (WC or TiCN) mixed with a ductile binder phase (Co/Ni/Fe). Extensive studies on monocarbide hardmetal compositions such as WC-Co, WC-Ni, NbC-Co, NbC-Ni, VC-Ni, Cr 3 C 2 -Ni, etc., exist in the literature [1][2][3][4][5][6]. Other carbides such as TiC, TaC, and NbC are also present as a mixed carbide composition, such as (Ti, Ta, Nb, W)C, for better wear resistance, hardness, and toughness [7].…”

Dense, high-entropy carbide cobalt-bonded hardmetals with two different compositions, namely (Hf-Ta-Ti-Nb-V)C-19.2 vol% Co and (Ta-Ti-Nb-V-W)C-19.2 vol% Co, were successfully manufactured by gas pressure sintering (SinterHIP) at 1400 °C and 100 bar Ar pressure. The microstructure of these hardmetals consists of a rigid skeletal carbide phase embedded in a tough Co binder phase. EDS mappings showed that the high-entropy carbide phase did not decompose and that a typical hardmetal microstructure was realized. Only in the case of the (Hf-Ta-Ti-Nb-V)C-Co hardmetal was some undissolved TaC and HfO2, as well as some clustered vanadium titanium carbide phase, found, resulting in a split-up of the HEC phase into two very similar HEC phases. This resulted in a reduced hardness to fracture toughness ratio for this composition. Measurements of magnetic saturation polarization showed values between 57.5% and 70% of theoretical magnetic saturation polarization, indicating marginal dissolution of the carbide-forming metal elements in the binder phase. The hardness value HV10 for (Hf-Ta-Ti-Nb-V)C-19.2 vol% Co was 1203 HV10 and 1432 HV10 for (Ta-Ti-Nb-V-W)C-19.2 vol% Co.
