The goal of the work: create new composite materials for the armor elements based on boron carbide activated by metal borides, oxides, and silicides. Methods of research: spark plasma sintering, differential thermal analysis, energy dispersive X-ray spectroscopy, scanning electron microscopy, X-ray phase analysis, X-ray crystal structure analysis, hydrostatic density measurement, Vickers hardness measurement. Obtained results: laboratory prototypes of ceramics for armor elements were synthesized by the spark plasma sintering method - new superhard ceramics of the initial compositions B4C, B4C+TiB2, B4C+CrB2, B4C+VB2, B4C+TiSi2, B4C+YB6, B4C+Y2O3, B4C+Nd2O3, which are characterized by high values of relative density (>96 %) and hardness (30-47.3 GPa). The products are promising materials for the development of elements for individual ballistic protection.   Product Description popup.authors Ivanushko Andriana Babizhetskyy Volodymyr Gnilitskyi Yaroslav Demchychyn Anatolij Zaremba Oksana Zelinskiy Anatoliy Miliyanchuk Khrystyna Yu. popup.nrat_date 2023-07-03 Close
