“…In addition, (W,Ti)B 2 coatings have shown higher corrosion resistance than unalloyed WB 2 . The addition of zirconium [ 7 ] leads to an increase in the thermal stability without affecting the mechanical properties. Fuger et al [ 5 ] show that the addition of tantalum can increase the hardness up to 45 GPa while only lowering the fracture toughness to 3 MPa × m 1/2 , which is higher than for TiN coatings.…”

We present the deposition and characterization of tungsten-tantalum diboride (W,Ta)B2 coatings prepared by the high-power impulse magnetron sputtering technique. We evaluated the influence of pulse duration and substrate bias on the properties of (W,Ta)B2 films. A high hardness of up to 35 GPa measured by nanoindentation was simultaneously obtained with good elastic properties. Changing the pulse duration greatly affected the B/(W+Ta) atomic ratio, which influenced the properties of the coatings. The deposited films are thermally stable at up to 1000 °C in vacuum and are able to withstand oxidation at 500 °C.

“…Tungsten–iridium- and tungsten–iridium–boron-based materials are commonly demanded in the industry. These materials can be used for fabricating engines, cutting tools, wear-resistant and antioxidant coatings, as well as electrocatalysts due to the outstanding properties of both metals, including high melting points (2447 °C for Ir and 3422 °C for W), high level of mechanical properties, high hardness, and good oxidation resistance [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ]. There are numerous examples where the synergistic effect of both metals significantly improved the properties of designed materials.…”

In the present study, we perform a systematic examination of the products formed by mixing and heating of tungsten boride and iridium powders at different ratios in a broad temperature range using qualitative and quantitative X-ray analysis and time-of-flight neutron diffraction (TOF-ND), in combination with scanning electron microscopy/energy-dispersive spectroscopy (SEM/EDS) performed at different accelerating voltages. The well-known and unknown ternary W–Ir–B phases were detected. The Vickers microhardness value for the new ternary W2Ir5B2 boride was measured. Based on these findings, the ternary W2Ir5B2 boride can be considered hard.

Potentially superhard $$W_{1-x}Zr_{x}B_2$$ W 1 - x Z r x B 2 polymorphs, hP6-P6$$_{3}$$ 3 /mmc-WB$$_2$$ 2 and hP3-P6/mmm-WB$$_2$$ 2 , were thoroughly analyzed with zirconium doping in the range of x=0-25%, within the framework of the first-principles density functional theory, from both a structural and a mechanical point of view. The obtained results were subsequently compared with the properties of material deposited by the magnetron sputtering method. All predicted structures are mechanically and thermodynamically stable. Theoretical calculations suggest a decrease in hardness $$H_v$$ H v and fracture toughness $$K_{\text {IC}}$$ K IC of the hP6 phase with zirconium doping but no such effect on the hP3 phase. It was observed that an additional defect in the analyzed structure significantly weakens the hP6 phase but strengthens the hP3 phase. The deposited films are characterized by greater hardness but lower fracture toughness. The results of experiments show that not only is solid solution hardening responsible for strengthening the predicted new material but also the change in microstructure, the Hall–Petch effect and vacancies.
