Experimental data on densification dynamics, phase composition, morphology, mechanical properties, grain size distribution WC-10%wtCo using spark plasma sintering (SPS) within range 1000-1200 °C are presented. high quality product is provided by advanced high-speed powder mixture SPS-consolidation at achieving degree minimal calculated growth 1200 °C.
Reconstructive and regenerative bone surgery is based on the use of high-tech biocompatible implants needed to restore functions musculoskeletal system patients. Ti6Al4V one most widely used titanium alloys for a variety applications where low density excellent corrosion resistance are required, including biomechanical (implants prostheses). Calcium silicate or wollastonite (CaSiO3) calcium hydroxyapatite (HAp) bioceramic material in biomedicine due its bioactive properties, which can...
MXenes are of great practical interest. While the physical properties such a well-known MAX phase as Ti3AlC2 and Ti3C2 MXene that is based on it have been widely studied, extremely important to study new four-component MAX-phases them. To do this, first, necessary characterize obtained materials. In this work, Ti3-xNbxC2 was characterized. Since material fairly new, there no crystallographic data for systems in international databases. We proposed method determination main unit cell...
To study the material based on binary system Ti + Cu (50% atm), samples were produced from powders of commercially pure metals and additionally ground in a ball mill (final size about 12 µm) by spark plasma sintering. The following intermetallic phases obtained materials: CuTi2, TiCu, Ti3Cu4. materials have hardness 363 385 HV (800 900 °C), microhardness 393 397 µHV, density 4.24 5.23 kg/m3, resistance to corrosion acids (weight gain 0.002% after 24 h testing according ISO 16151 for sample...
