Abstract:
At this stage of industry development, composite nanostructure materials are widely used. Among them, materials containing carbides and borides of metals TiB<sub>2</sub> / TiC and ZrB<sub>2</sub> / ZrC are especially notable.<br />In this presented work, the task is to perform a complete thermodynamics analysis — FTA (Full thermodynamics analysis) [1] on the process of receiving carbides and boride of the titanium and zirconium (Ti-B-O-C, Zr-B-O-C), and on the basis of this analysis of experimental studies of nano-structured composite materials.<br />The innovation of the work is studying the physical and chemical bases of high-temperature processes of receiving carbides and borides of the specified systems, that will give the chance of carrying out the minimum quantity of experiments. <br />FTA of the Ti-B-O-C system in vacuum for the following structures is carried out: 2TiO<sub>2</sub>+B<sub>2</sub>O<sub>3</sub>+8C=TiB<sub>2</sub>+TiC+7CO (1); 2ZrO<sub>2</sub>+B<sub>2</sub>O<sub>3</sub>+8C=ZrB<sub>2</sub>+ZrC+7СО (2).<br />On the basis of this analysis, experimental research is carried out on receiving composite materials TiB<sub>2</sub> / TiC and ZrB<sub>2</sub> / ZrC. X-ray diffraction patterns of the obtained powders indicate that in general, mixes TiB<sub>2</sub>/TiC and ZrB<sub>2</sub>/ZrC result.
