Abstract:
To enhance the properties of tungsten diboride, solid solutions of this ceramic with transition metals such as titanium, zirconium, and tantalum were synthesized by spark plasma sintering from the pure elements. The metallic content was in all cases 24 at.%. The specimens were characterized using scanning electron microscopy and energy-dispersive X-ray spectroscopy for microstructure analysis, X-ray diffraction for phase identification as well as measurements of density and electrical conductivity. Based on the analysis of sintering curves, two stages of reactive spark plasma sintering were observed. For instance, in the W0.76Ta0.24B2 sputtering target, the WB2 and TaB2 phases were synthesized. The density changes along the diameter from 8.99 in the center to 8.29 g|cm3 on the border of the disc. The usable properties of the obtained materials mean that W-TM-B compounds may be used such as sputtering targets for high-power impulse magnetron sputtering.
