| Samenvatting: | Title screen The structure and defects self-healing mechanism of ceramic composite materials (ZrB[2] -ZrC-SiC)-ZrO[2] depending on the volume fraction of zirconia (0, 5, 10, 15 vol.%) werestudied. Increasing of ZrO[2] content led to higher composites compaction obtained by sintering under a pressure of 30 MPa at a temperature of 1900 °C, and to decreasing of the ceramic particles average size. Annealing in the air at 1200 °C led to (ZrB[2] -ZrC-SiC)-ZrO[2] composites oxidation with the formation of an oxide layer consisting of a porous ZrO[2] matrix impregnated with borosilicate (B[2]O[3]+SiO[2]) glass. The thickness of the oxide layer increased with the increasing of zirconia volume fraction. The percentage of defects self-healing after °C led to the complete defects healing with ZrO2 content above 10 vol. %. The effect of temperature of 1600 °C on ceramic composites led to the complete defects healing, regardless of the ZrO[2] content. Режим доступа: по договору с организацией-держателем ресурса |
