Ceramic nanolaminates-Processing and application

摘要

The self-propagating high-temperature synthesis (SHS) has been used in authors' works for preparation of ceramic nanolaminates, namely Ti_3SiC_2, Ti_3 AlC_2 and Ti_2 AlN. The possibility of obtaining near-single-phase materials, processing of SHS products into sinterable powders and densification of the powders by sintering and hot-pressing are discussed. Finally, polycry stalline nanolaminate materials with controlled phase composition and microstructure have been obtained. The materials have been investigated as structure materials by testing their mechanical properties. The possibility of using of prepared powders to obtain ceramic composites, ceramic bonds and FGM materials, as well as their potential application are discussed.
