Abstract |
The spark plasma sintering (SPS) technique keeps the leading edge position among contemporary consolidation methods suitable for manufacturing of nanostructured materials. Conventional ceramic paradigm itself represents a combination of particulate technologies methods, which include powder synthesis stage, powder consolidation, sintering, and treatment, if necessary. This approach is quite universal, but it has a number of restrictions, mostly because of difficulties to achieve uniform component distribution in the bodies of multiphase materials. The nanocomposites represent the most promising class of bulk nanomaterials. Engineering of nanocomposites creates unlimited resources to prevent grain growth during consolidation and marry the best combination of structural and functional properties, however, their manufacturing is a challenge. Recently developed TiN-TiB2, TiN-Si3N4, TiN-AlN, and other nanocomposites obtained by SPS techniques, their competitive mechanical properties will be illustrated. Numerous examples of experimental researches and characterizations of ceramic matrix nanocomposites obtained by both particle consolidation and polymer destruction methods under SPS conditions will be overviewed and potential applications of such materials described. |
