Authors: | Zgalat-Lozynskyy O.B. | |
Summary: | A market of wearproof ceramics analysis is conducted. Advantages of nanocomposites of the tribological application are shown by comparison to traditional coarse grains ceramics. The prospects of modern technologies introduction for the production of wearproof nanocomposites and implementation with products to the Ukrainian market of ceramic materials are considered. | |

060 Superplastic deformation of Si3N4 based nanocomposites reinforced by nanowhiskers |
Authors: | O. Zgalat-Lozynskyy, M. Andrzejczuk, V. Varchenko, M. Herrmann, A. Ragulya, A. Polotai | |
Summary: | A superplastic deformation of pre-sintered Si3N4-based nanocrystalline ceramics and Si3N4 nano-whisker reinforced composites has been investigated. Superplastic deformation tests have been carried out in the temperature range from 1500° to 1600°C under 56 kN compression in nitrogen. During the tests, nano-composites exhibited high rates of deformation (1.6-5.4 10-3 s–1) and the formation of a pore free and anisotropic microstructure. Mechanical and tribological properties of the nano-composites after superplastic deformation have been investigated. | |

060 Nanocomposites based on refractory compounds, consolidated by Rate-Controlled and Spark-Plasma Sintering (Review) |
Authors: | O Zgalat-Lozynskyy | |
Summary: | ate-controlled sintering and spark plasma sintering are considered the most promising methods to produce dense nanoctructured ceramics. Refractory compounds are used to demonstrate the application of methods for controlling the densification rate and nonlinear heating and loading conditions to produce dense nanocomposites with 30–70 nm grains. The mechanical and tribological properties of ceramics with grains from 50 to 500 nm in size are compared. The effect of increase in the mechanical (5–15%) and tribological (to 50%) characteristics of nanocomposites consolidated by rate-controlled sintering and modified nonlinear spark plasma sintering is studied. Nanocomposites based on refractory nitrides and borides are regarded as promising materials for creating a new generation of cutting tools, as well as wear-resistant ceramics for wide application. | |
