| Summary: | Заглавие с экрана Zirconia ceramics reinforced with 0, 0.1, 0.5, and 1 wt.% single wall carbon nanotubes were fabricated by spark plasma sintering. The sintering was performed at 1500°C with a dwell time of 10 min, with heating and cooling rates of 100°C/min, and uniaxial pressure of 40 MPa was applied. Relative densities of the obtained pellets were calculated by weighing the pellets and measuring their dimensions. The highest value for microhardness was obtained for the pure ZrO[2] (14.72 GPa), and it decreased with the increase in the content of carbon nanotubes. On the other hand, fracture toughness of the obtained composites increased with the increase in carbon content. The highest value for fracture toughness was obtained for the composite with 1 wt.% of CNT (6.97 MPa·m{1/2}). |
