Development of manufacturing technique of ceramic, metal-ceramic and metalopolimerceramic composite armor by using superstrength, superhard reinforced ceramic materials

The technology of manufacturing of ceramic and metal superstrength composites (40 GPa compressive strength) superhard (30 GPa) reinforced materials based on boron carbide and boride of titanium or aluminum, nanostructured B6O by hot pressing. It is established that changing technological parameters of hot pressing allows controlling chemical, phase composition and structure (grain size, the geometric dimensions of the reinforcing component). It is shown that the reinforced ceramic materials have high mechanical properties and the use of proven prospects for making a fundamentally new class of ceramic and metal composites, able to work effectively under high dynamic loads. Developed new reinforced Ti-TiB composite showed improved mechanical and functional properties in experimental trials in heavy abrasion and shock loads at high speeds. Due to the effect of reinforcement the strength of the developed composite increases in over twice, Moreover due to the reinforcement in the composite the self-sharpening effect was developed and observed. It can significantly increase the time of continuous operation of cutting parts and thus significantly improve the performance of cutting, which makes the material competitive in market of cutting materials.
